Installation FAQ

{{FAQ}}

==PHP - is it installed and what version do I have?==

Make a new file on your web site called ''info.php'', containing the following text, and call it from your browser:

<?PHP phpinfo() ?>

If nothing happens then you don't have PHP installed or your webserver is not configured to handle .php files properly. See the installation docs for some information about where to download it for your computer. See the [[phpinfo]] page for details about the content of this page.

== System information needed for Installation Forum ==
When posting questions to the installation forum, try to provide as much background information as possible about your moodle system. Use this template to copy and paste into your post:
* Server OS name (version also if possible):
* Browser name (version also if possible):
* Moodle version:
* Moodle config.php attached?(Y/N):
* Phpinfo attached? (Y/N):

For the last two items, try to include the following in your post as an attachment:
* A copy of your phpinfo output as shown in your browser (see the instructions above for an explanation of how to obtain this).
* A copy of the Moodle configuration file. This is located in the directory moodle and is named config.php

Copy and paste both of these into a single text file (using vi, Notepad, etc) and attach this to your post.

If you cannot provide your phpinfo, try to copy & paste and complete these in your post:
* Apache version:
* MySQL version:
* PHP version:

For installation on web hosting accounts: contact your support desk who should be able to tell you this information.

: '''Security Warning''': Make sure you edit any files and delete any passwords before posting onto the forum.

==What & where are Moodle's configuration settings stored?==
Configuration settings are stored in the config.php file stored in your moodle folder. This file is created during the installation process. If there is a problem and the installation cannot create the file, you can try creating it manually from the [[Configuration file]] docs. Please remember that manually editing the file is not recommended and may lead to blank pages, especially if there are additional spaces and/or lines after the final php closing tag "?>".

==Running a health check==
Moodle contains a script that will help identify common php and webserver configuration problems as well as configuration problems. It is a good idea to run this script to check if you are having post-installation problems. Use your browser to run this file:

http://www.mymoodle.com/moodle/admin/health.php

Change the above line if you have installed moodle in the webroot instead of a folder inside the webroot.

==Downloading previous releases of Moodle==
* '''Generic Packages''': If your server does not meet the [[Installing_Moodle#Requirements | requirements]] for the current version of Moodle, you can download previous releases by using this URL:
http://download.moodle.org/stable[version_number]
:For example: to download Moodle version 1.5, use http://download.moodle.org/stable15. You'll see a directory tree with the files displayed. Click on the one you want and download as normal - if you require the latest update of the version, scroll to the end of the list and download the "moodle-latest" file. Changes made in the version in the last month are listed in the "CHANGES" file. The files contain Moodle code and are not the Windows or Mac packages - so you need to have a webserver, a database server and PHP already installed. The earliest version available is Moodle 1.3.
* '''Windows Packages''': To download previous releases of the Moodle packages for Windows, use this URL:
http://download.moodle.org/windows/MoodleWindowsInstaller-latest-[version_number].zip
* '''Mac Packages''': To download previous releases of the Mac pacakges, use either of these URLs (depending on whether you need the Intel or PPC package):
http://download.moodle.org/macosx/Moodle4Mac-Intel-[version_number].dmg
http://download.moodle.org/macosx/Moodle4Mac-PPC-[version_number}.dmg
* '''Using CVS''': You can also use CVS to download older releases and incremental releases of the Moodle generic packages, e.g. Moodle 1.5.4 - see the [[CVS_for_Administrators | CVS documentation]].

== How to enable and check PHP error logs==
PHP can be set up to log errors in a variety of different ways: two of these involve the use of the php.ini file and the ini_set command.
* '''Using the php.ini file''': The log settings are contained in the php.ini file stored on the server. If you don't know where that is, edit your Moodle ''config.php'' and add the following as the second line

phpinfo();

:then reload the web page. Look for the entry '''Configuration File (php.ini) Path'''.

:When you have located php.ini open it in your favorite text editor. Find the '''Error handling and logging''' section of the php.ini file. Make sure that both '''display_errors = On''', '''display_startup_errors = On''' and '''log_errors = On''' are present and uncommented. Check the value of '''error_log''' - this tells you the location of the file errors are logged to. If it is commented out then errors will be sent to the web server error log file. Remember, if you make any changes to this file you will need to restart the web server (or just reboot the server).

* '''Using ini_set commands''': If you are using Moodle 1.8 or higher, the previous steps are not enough. In those versions error logging parameters are dependant on certain administrative settings that you specify in the debugging section. The problem is that if you can't access the administrative pages, you can't set the debugging options. So the only way to modify them is by adding the following lines to your config.php file, just before the last line (the one containing a single'?>' only):

ini_set ('display_errors', 'on');
ini_set ('log_errors', 'on');
ini_set ('display_startup_errors', 'on');

:This will enable the same settings specified above even if Moodle sets them otherwise.
:'''Important''': Remember to put them just before the last line of config.php.

==Any text I add with an apostrophe (') or a quote (") causes errors or comes up with a slash added==

Problems caused by apostrophes are caused by incorrect "magic quotes" settings. Moodle requires the following settings in the php.ini file (which are usually the default):

magic_quotes_gpc = On
magic_quotes_runtime = Off

Please see [[Installing Moodle]] for more details.

==Email copies are not being sent from my forums==

You ''must'' set up cron properly if you want Moodle to send out automatic email from forums, assignments etc. This same process also performs a number of clean-up tasks such as deleting old unconfirmed users, unenrolling old students and so on.

Basically, you need to set up a process to regularly call the script <code><nowiki>http://yoursite/admin/cron.php</nowiki></code>. Please refer to the [[Cron|cron instructions]].

'''Tip:''' Try the default setting in Moodle variables page. Leave the smtphost blank. This will be acceptable for the majority of users.

'''Tip:''' Make sure that allowuseremailcharset in Administration > Configuration > Variables > Mail is set to No. Setting this to Yes might cause this problem in some versions of Moodle.

==Error: database connection failed==

If you get errors like "database connection failed" or "could not connect to the database you specified", here are some possible reasons and some possible solutions.

* Your '''database server''' isn't installed or running. To check this for MySQL try typing the following command line
$telnet database_host_name 3306
:You should get a cryptic response which includes the version number of the MySQL server.
* If you are attempting to run '''two instances of Moodle on different ports''', use the ip address of the host (not localhost) in the $CFG->dbhost setting, e.g. $CFG->dbhost = 127.0.0.1:3308.
* You don't have the '''PHP mysql or postgresql extensions''' installed (please refer to FAQ re. whether PHP is installed).
* You haven't created a '''Moodle database and assigned a user''' with the correct privileges to access it.
* The '''Moodle database settings''' are incorrect. The database name, database user or database user password in your Moodle configuration file ''config.php'' are incorrect. Use phpMyAdmin to set up and check your MySQL installation.
* Check that there are '''no apostrophes or non-alphabetic letters''' in your MySQL username or password.
* You are using MySQL version 4.1 or higher but the PHP MySQL extension is pre-4.1 (check in your phpinfo output). In this case the '''default password hashing algorithm''' is incompatible with that available in the PHP mysql extension versions 4.x.x. Use these MySQL commands to change the passwords to the old format:

mysql>SET PASSWORD FOR 'root'@'localhost' = OLD_PASSWORD('password');
mysql>SET PASSWORD FOR 'moodleuser'@'localhost' = OLD_PASSWORD('password');

:Also, consider upgrading your PHP MySQL extension. See [http://dev.mysql.com/doc/mysql/en/old-client.html this MySQL document] for further information on how to deal with this problem.
* You are using Fedora core 3 or some other Linux system with '''SELinux installed''' and enabled. See the following URL for information on how to disable SELinux: http://fedora.redhat.com/projects/selinux/
* Mac OSX users -- if you are running MySQL on a Mac OSX, try changing '''$CFG->dbhost''' from 'localhost' to '127.0.0.1'
'''See also''': MySQL page on [http://dev.mysql.com/doc/refman/5.0/en/common-errors.html common errors] which lists several possible scenarios for connection failure, with advice on how to fix the problems.

==I can't log in - I just stay stuck on the login screen==

The most common cause for this is that your own computer (not your Moodle server) has a firewall that is stripping referrer information from the browser. Here are some instructions for fixing [http://service1.symantec.com/SUPPORT/nip.nsf/46f26a2d6dafb0a788256bc7005c3fa3/b9b47ad7eddd343b88256c6b006a85a8?OpenDocument&src=bar_sch_nam Norton firewall products].

The server admin can also fix this for everyone by changing the ''secureforms'' variable to 'No' in the security section of Administration >> Configuration >> [[admin/config|Variables]].

Another possible cause of this problem is that sessions are not configured properly on the server. You can test this by calling the script <nowiki>http://yourserver/moodle/lib/session-test.php</nowiki>.

If you are still having problems, read the [[Can_not_log_in | Cannot log in]] page.

==I can't log in with message "Please verify that the current setting of session.save_path is correct" ==

This error occurs when PHP is having problems saving its session files. You may also see these other error messages displayed on the screen or in your log files:

Warning: Unknown: open(some-path/sessions/sess_acbf942a7399db3489ffa910e35d5242, O_RDWR)
failed: Permission denied (13) in Unknown on line 0

Warning: Unknown(): open(some-path/sessions/sess_acbf942a7399db3489ffa910e35d5242, O_RDWR)
failed: No space left on device (28) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current
setting of session.save_path is correct (some-path/sessions) in Unknown on line 0

To temporarily bypass these errors, '''use database sessions''' by editing your [[Configuration_file | moodle configuration file]] and adding this line:

$CFG->dbsessions = true;

Database sessions may overload your mysql database and are not ideal in a shared hosting environment, so if this solves the problem, you can start fixing the problem as follows:
* Check '''access rights'''. The session.save_path should be accessible by the apache user. Try this command:

chown -R apache:apache some-path/sessions

:This assumes that 'apache' is the name of the user your webserver runs under - it could also be 'nobody'.
* Check the '''permissions''' to the directory that PHP is trying to save to (session.save_path = some-path/sessions). Set the permissions initially to 0777 (everyone read, write, execute) with this command:

chmod -R 0777 some-path/sessions

:If this fixes the problem, reduce the permissions (700 is recommended).

'''See also''': Session problems can be specific to your server environment. As an example, see [http://moodle.org/mod/forum/discuss.php?d=55925#254596 this forum discussion] about session problems with Lycos hosting.

==I log in but the login link doesn't change. I am logged in and can navigate freely.==

Make sure the URL in your <code>$CFG->wwwroot</code> setting is exactly the same as the one you are actually using to access the site.

==I keep getting this error: A server error that affects your login session was detected.==

Please refer to the Using Moodle forum discussion [http://moodle.org/mod/forum/discuss.php?d=73716 A server error that affects your login session was detected. Please login again or restart your browser.].

==I keep getting this error: Failed opening required '/web/moodle/lib/setup.php'==

In your ''config.php'', the setting that you use for the dirroot variable must be the complete path from the root of your server's hard drive.

Sometimes people only use the path from their home directory, or relative to the root of the web server directory.

==My pages show fatal errors such as : Parse error, call to undefined function: get_string()==

If you see errors like:

Parse error: parse error, unexpected T_VARIABLE in /path/to/moodle/config.php on line 94
Fatal error: Call to undefined function: get_string() in /path/to/moodle/mod/resource/lib.php
on line 11

then you have probably left out a semi-colon or closing quote from a line in ''config.php'' (previous to line 94).

Another possibility is that you edited ''config.php'' in a program like Word and saved it as a HTML web page, instead of using a plain text editor like Notepad.

Another thing to check, particularly if you are using 3rd party modules or plugins, is whether any of the php scripts use short open tags (<? ?>) instead of proper ones (<?php ?>). Short tags are bad for various reasons, so first contact the author of that extension to tell them about the problem. Then either replace short tags with conventional ones, or set this line in php.ini:

short_open_tag = On

You should never find short tags in core moodle code. If you do, please file a bug in the bug tracker.

==Serious Error! Could not set up the site!==

Please refer to the Using Moodle forum discussion [http://moodle.org/mod/forum/discuss.php?d=32071 Serious Error! Could not set up the site!].

==Uploaded files give "File not found"==

For example: Not Found: The requested URL /moodle/file.php/2/myfile.jpg was not found on this server.

Your web server needs to be configured to allow the part of the URL after a script name to be passed directly to the script. This is usually enabled in Apache 1, but is usually disabled by default in Apache 2. To turn it on, add this line to your ''httpd.conf'', or to a ''.htaccess'' file in your local directory (see [[Installing Moodle]] for more details):

'''AcceptPathInfo''' on

Note, this will ONLY work for Apache versions 2.x.

If you are not using Apache 2 and you still have this problem (unlikely) then you can switch Moodle to use an alternative method. The disadvantages are a slight loss of performance for your users and you won't be able to use relative links within HTML resources.

To use this alternative method, you should change the ''slasharguments'' variable in the Operating System section of Administration >> Configuration >> [[admin/config|Variables]]. You should now be able to access your uploaded files.

==When I go to the admin page, I get told to make dirroot blank!==

If you see errors like this:

Please fix your settings in config.php:
You have: $CFG->dirroot = "/home/users/fred/public_html/moodle";
but it should be: $CFG->dirroot = "";

then you have encountered a small bug that occurs on some servers. The problem is with the error-checking mechanism, not with your actual path. To fix it, find this line (line 66) in the file ''admin/index.php'':

if ($dirroot != $CFG->dirroot) {

and change it to this:

if (!empty($dirroot) and $dirroot != $CFG->dirroot) {

==When trying to add a resource I receive error messages==

Assuming you are using Apache, then it's quite likely that your setting in ''config.php'' for <code>$CFG->wwwroot</code> is different from the actual URL you are using to access the site. Also try turning off the ''secureforms'' variable in the security section of Administration >> Configuration >> [[admin/config|Variables]].

==Why are all my pages blank?==

Check the dirroot variable in ''config.php''. You must use complete, absolute pathnames e.g.

$CFG->dirroot = "d:\inetpub\sites\www.yoursite.com\web\moodle";

Another reason might be that PHP has not been configured to support MySQL. This is common on Redhat and OpenBSD installations. In this case, an error is generated, but since error displays are often disabled by default, all that is seen on the browser is a blank screen. To enable PHP error displays, set these lines in your ''php.ini'' file and reload the web page.

display_errors = On
display_startup_errors = On

To determine if MySQL support is your problem, insert this as the second line in your ''config.php'' file

phpinfo();

then reload the web page. Examine the output closely to see if MySQL is supported. If not look for a package you are missing.

== Why is a particular page blank or incomplete? ==

*'''Check your web server log files!!'''
:If a particular page is blank or incomplete (it doesn't display the footer), before you do anything else [[Installation_FAQ#How_to_enable_and_check_PHP_error_logs | check your error logs]]. Having established that PHP error logging is working, reproduce the error. Immediately check the error log file right at the end. Hopefully you will see a PHP error message at or very near the end of the file. This may solve your problem directly or makes it a lot easier to diagnose the problem in the Moodle forums.

*If you are '''upgrading to a new version of Moodle''', check that you do not have an old version of a non-standard block or module installed. Remove any such blocks or modules installed remove them using the admin settings page and start the install process again.

*If you '''do not see any blocks listed''', turn editing on and remove any blocks that you have added to that page and try reloading.

==Installation hangs when setting-up database tables==
*Sometimes the installation will hang when setting up tables. This will be an abrupt hang with half the page displayed in the browser and/or other outputs removed, e.g. the “Scroll to continue” link is displayed but no “Continue” button is there. If this is the case, it is usually a mysql error and not a php error. Check that there is no limit placed on your mysql database, e.g. a "questions" limit.

*If the install is on a webhost, adding the following line to the .htaccess file in the moodle directory has been known to solve the problem.
AddType x-mapp-php5 .php

*Try also renaming the .htaccess file so that it is disabled.

*You may also want to look and see if you've customized any of your code. Look at the last successful table, and then look at the block, mod, or other code that is referenced by that table. For example, if your install hangs and continues to say that the forum tables were successful as the last message, look at /mod/forum/ for any custom code. If you have customized code, backup those files and replace with the correct files. You can then restart the install by renaming config.php or reinstalling your database from the backup. If your install is successful, you can make your code changes back into the stock Moodle code.

*It may also be that the "memory_limit" in your php.ini is set too low. Please check your php.ini file and allocate at least 40MB, as recommended, as the maximum amount of memory a script may consume (ver 1.8).

==Why can't I upload a new image into my profile?==

If you don't see anything on your user profile pages to let you upload user images then it's usually because GD is not enabled on your server. GD is a library that allows image processing.

1. Make sure '''GD has been included in your PHP installation'''. You can check this by going into Administration >> Configuration >> [[Variables]] and looking for the gdversion setting. This setting is chosen automatically every time you visit that page. If it shows GD version 1 or version 2 then everything should be fine. Save that configuration page and go back to your user profile.

2. If Moodle thinks GD is not installed, then you will need to '''install the GD library'''.
*On Unix you may need to re-compile PHP with arguments something like this:

./configure --with-apxs=/usr/local/apache/bin/apxs --with-xml --with-gd
--with-jpeg-dir=/usr/local --with-png-dir=/usr --with-ttf --enable-gd-native-ttf
--enable-magic-quotes --with-mysql --enable-sockets --enable-track-vars
--enable-versioning --with-zlib

* On Windows this is usually a matter of "turning on" the extension in PHP by editing your php.ini file. To do this remove the semicolon for the php_gd2.dll extension - check that this file is actually present in your php extensions folder first (search your php.ini for extension_dir to determine where this points to on your hard disk). You should then have a line that looks like this:
extension=php_gd2.dll

:Windows users should see the [[Installing AMP|installation instructions]] for further help.

3. Remember to '''restart your webserver''' (if possible) and re-visit the Moodle configuration page after making any changes to PHP so it can pick up the correct version of GD.

==Why do I keep getting error messages about "headers already sent"?==

If you see errors like this:

Warning: Cannot add header information - headers already sent by
(output started at /webs/moodle/config.php:87) in /webs/moodle/lib/moodlelib.php
on line 1322

Warning: Cannot add header information - headers already sent by
(output started at /webs/moodle/config.php:87) in /webs/moodle/lib/moodlelib.php
on line 1323

Warning: Cannot add header information - headers already sent by
(output started at /webs/moodle/config.php:87) in /webs/moodle/login/index.php
on line 54

you have blank lines or spaces after the final <code>?></code> in your ''config.php'' file. Sometimes text editors add these - for example Notepad on Windows - so you may have to try a different text editor to remove these spaces or blank lines completely.

== Why doesn't my Moodle site display the time and date correctly? ==

Each language requires a specific language code (called a '''locale''' code) to allow dates to be displayed correctly. The language packs contain default standard codes, but sometimes these don't work on Windows servers.

You can find the correct locale codes for Windows on these two pages: [http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_language_strings.asp Language codes] and [http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_country_strings.asp Country/region] codes (e.g. "esp_esp" for spanish)

These new locale codes can be entered on the Administration >> Configuration >> [[admin/config|Variables]] page, where they override the ones in the currently chosen language pack.

==I receive this error "500:Internal Server Error"==
You'll get this error message if there is a syntax error in your .htaccess or httpd.conf files. You will also see this error if your server does not support .htaccess files, especially if it is running PHPsuexec. Also, you may have a directive in your .htaccess or httpd.conf files which are not compatible with your web server version.

==How do I uninstall Moodle?==
'''Moodle package installation''': If you have downloaded a Moodle package, simply uninstall using your system commands. On Windows PCs, you should access the Control Panel -> Add/Remove Programs. Select the package name and click Change or Remove Programs.

'''Webhost/manual installation''': If you have installed Moodle manually or have installed onto a webhost, follow these steps:
*Delete the moodle database using this mysql command (or delete using your mysql client, e.g. PHPMyAdmin):
<pre>sql>DROP DATABASE moodle;</pre>
:In the above example replace 'moodle' with the name of the moodle database you created when installing.
*Delete the moodledata directory. If you, or your users, have uploaded materials into this directory take a copy of these before deleting this directory.
*Delete the moodle directory itself. This will delete all of the moodle PHP script files.

==How do I upgrade Moodle? Do I just overwrite the files?==
Do not overwrite files, it may cause strange errors. You should read the [[Upgrade]] documentation before proceeding.

==Migrating Moodle to a new site or server==
Migrating Moodle means that you have to move the current installation to a new server, and so may have to change IP addresses or DNS entries. To do this you will need to change the $CFG->wwwroot value in the config.php on the new server. You will also have to change any absolute links stored in the database backup file (before restoring the file on the new server) either using the admin/replace.php script, your text editor or another "search and replace" tool, e.g. sed. For more details see the [[Moodle_migration | Moodle Migration]] page.

==Fatal error allowed memory size exhausted. How do I increase my php memory limit?==
You will sometimes see an error message something like this:
Fatal error: Allowed memory size of 67108864 bytes exhausted
(tried to allocate xx bytes) in /var/www/moodle/yyyy.php
This error means that the php memory_limit value is not enough for the php script. The memory_limit value is the "allowed memory size" - 64M in the example above (67108864 bytes / 1024 = 65536 KB. 65536 KB / 1024 = 64 MB). You will need to increase the php memory_limit value until this message is not shown anymore. There are two methods of doing this.
*On a hosted installation, add the following line to your .htaccess file (or create one in the moodle directory if it does not already exist):
php_value memory_limit <value>M
Example: php_value memory_limit 40M
*If you have your own server with shell access, edit your php.ini file (make sure it's the correct one by checking in your phpinfo output) as follows:
memory_limit <value>M
Example: memory_limit 40M
Remember that you need to restart your web server to make changes to php.ini effective. An alternative is to disable the memory_limit by using the command ''memory_limit 0''.

----
==Why does my new installation display correctly on the server, but when I view it from a different machine, styles and images are missing?==
In the installation instructions, one of the suggested settings for 'webroot' is 'localhost'. This is fine if all you want to do is some local testing of your new Moodle installation. If, however, you want to view your new installation from another machine on the same local area network, or view your site on the internet, you will have to change this setting:
*For local testing, 'localhost' is fine for the webroot.
*If you want to test your site from other machines on the same local area network (LAN), then you will have to use the private ip address of the serving machine, (e.g. 192.168.1.2/moodle) or the network name of the serving computer (e.g. network_name_of_serving_machine/moodle) as the web root. Depening on your LAN setup, it may be better to use the network name of the computer rather than its (private) ip address, because the ip address can and will change from time to time. If you don't want to use the network name, then you will have to speak to your network administrator and have them assign a permanent ip address to the serving machine.
*Finally, if you want to test your new installation across the internet, you will have to use either a domain name or a permanent (public) ip address/moodle as your web root.

Installing AMP

Moodle is written in a scripting language called PHP and stores most of its data in a database. The recommendrd database is MySQL. Before installing Moodle you must have a working PHP installation and a working database to turn your computer into a functional web server platform. These packages can be tricky to set up for average computer users, so this page has been written to try to make this process as simple as possible for different platforms:

== Hosting Service ==

Unfortunately hosting services vary quite a lot in the way they work. Some will even install Moodle for you.

Most will offer a web-based control panel to control your site, create databases and set up cron. Some may also offer terminal access via ssh, so that you can use the command shell to do things.

You should work your way through the [[Installing Moodle|Installation guide]] and take each step at a time. Ask your hosting provider if you get stuck.

== Mac OS X ==

The easiest way to do this is use the Apache server that Apple provides, and add PHP and MySQL using Marc Liyanage's packages. Both of the pages below come with good instructions that we won't duplicate here:

* '''PHP''': Download from here: http://www.entropy.ch/software/macosx/php/
* '''MySQL''': Download here: http://www.entropy.ch/software/macosx/mysql/

Once these are installed the standard [[Installing Moodle|Installation guide]] should be fairly straightforward.

== Red Hat Linux ==

You should install all available RPM packages for Apache, PHP and MySQL. One package that people frequently forget is the php-mysql package which is necessary for PHP to talk to MySQL.

Once these are installed the standard [[Installing Moodle|Installation guide]] should be fairly straightforward.

A more detailed walkthrough is here: [[RedHat Linux installation]]

== Windows ==

The easiest way to do this is use one of the complete install packages available from the Downloads page at Moodle.org. [http://download.moodle.org/?lang=en]

Alternatively, use a package like EasyPHP that bundles all the software you need into a single Windows application. Note that the EasyPHP 1.7 uses the following somewhat older versions:

# apache 1.3.27 (currnet relases is 2.2.0)
# php 4.3.3 (current stable release is 5.1.3)
# mysql 4.0.15 (current release is 5.0.18)
# phpmyadmin 2.5.3

It should be noted that these are not the current releases. Also many menus for EasyPHP are still in French. Here are the steps from start to finish for this approach, XAMPP or Windows 2003 with IIS: [[Windows installation]].

==Testing PHP==
Once you have installed your web server and PHP you should be able to create a file (for example phpinfo.php in the document root) with the following in it:

<?phpinfo()?>

You should be able to open this file in a web browser by going to to the URL '''localhost/phpinfo''' and see a web page that has PHP status information in it such as [[phpinfo|this]].
