Critical to any installation using php is your php.ini file, which contains directives for you usage of php. This is especially true with respect to a number of moodle settings such as max upload and max post sizes with file upload
How php.ini is used
Sourcing
Search order and why that is important why phpinfo will not tell you what php.ini is being sourced site wide when you are suing php4
Invocation
Apached mod versus CGI Why you don't have to reread webserver files where you are using php via cgi
Manipulating php.ini
Editing the php.ini file generally
wrappers etc
Moodle specific php.ini settings
Common php.ini settings
register_globals = 0 ;(necessary)
safe_mode = 0 ;(necessary)
memory_limit = 40M ;(varies: minimum 16M, 32M Moodle v1.7, 40M Moodle v1.8, 128M large sites)
session.save_handler = files ;(unless you are using another handler, e.g. mm)
magic_quotes_gpc = 1 ;(preferred but not necessary, 0 will be highly recommended in 2.0)
magic_quotes_runtime = 0 ;(necessary)
file_uploads = 1
session.auto_start = 0 ;(necessary)
session.bug_compat_warn = 0
Max file size settings
You may also want to set other, optional php.ini file settings while you are already editing it. For instance, you may want to reset the maximum upload size of file attachments, which usually defaults to 2M(egabytes). For instance, to set these to 16 Megabytes:
post_max_size = 16M upload_max_filesize = 16M
