Setting up PhpStorm

PhpStorm is a commercial IDE, it is arguably the best IDE for PHP developers with features such as code completion, code inspection, phpunit support, Behat support, database editor, debugger, etc.

Installation

OS X

You can optionally install latest Java JDK 1.7.x from Oracle (Java 1.6 from Apple is not maintained much). By default PhpStorm uses only older 1.6.x java, but you can hack PhpStorm 7 to be compatible with Java 1.7 by editing the "PhpStorm.app/Contents/Info.plist" file, set JVMOptions - JVMVersion = 1.7*

General settings

Disable missing @throws tag warning in "Preferences / Project Settings / Inspections / PHP / PHPDoc"
Strip trailing whitespace from "Modified Lines" in "Preferences / IDE Settings / Editor"
Show line numbers in "Preferences / IDE Settings / Editor / Appearance"

Bug tracker integration

Add tracker linking in "Preferences / Version control / Issue Navigation"
Set Issue ID to "MDL-\d+" and Issue link to "https://tracker.moodle.org/browse/$0"

Code formatting

Setup coding style to use all rules from Coding style in "Preferences / Project Settings / Code Style / PHP" - this will allow you to use automatic code formatting and it does nice code formatting on copy/paste.
Set line separator to Unix in "Preferences / Project Settings / Code Style / General".
Set right margin to 132 or 180 in "Preferences / Project Settings / Code Style / General".

Install PHPUnit via Composer
Tell PHPStorm where is composer - go to "Preferences / PHP / Composer", fill in "Path to PHP executable", "Path to composer.phar", "Path to composer.json" and make sure the option "Add packages as libraries" is enabled.
Go to "Run / Edit configurations"
Add PHPUnit configuration by clicking on "+"
Click "Use alternative configuration file" and select your phpunit.xml file
Go to "Run / Run ..." and select your new PHPUnit configuration to run

Database editor

Click on the "Database" tab to see the database window
Click "+" in the top left and add "Database source" for your database
