PHP Editor

IntelliJ IDEA provides PHP support via a dedicated PHP plugin. Plugin functionality is similar to that of PhpStorm, a specialized PHP IDE built on IntelliJ platform.

We've collected some of the most exciting features that, in our opinion, the IDE provides. Just the top of the iceberg. Read the sections below, scan the screenshots and download the product to try it in action.

Intelligent Editor

Web IDE provides rich and intelligent code editor for PHP with syntax highlighting, on-the-fly error checking, and smart code completion.

Thorough source code analysis allows us to provide code completion even to an unannotated code, for example:

  • function return type is deducted from its body and return statements
    PHP: deduce function return type from return statements
  • class property types (and even declarations) are extracted from constructor code PHP code analysis
  • code completion for array indexes in PHP code.

File structure view and class, method and call hierarchy views allow for faster code review and navigation.

PHPDoc support

PHPDoc: @property & @method declarations completion & resolution

IDE editor considers PHPDoc for providing code completion based on @property, @method and @var annotations.

Variables name and types are completed when writing PHPDoc.

PHP code refactorings also consider PHPDocs to keep them up to date.

PHP 5.4 Language Features Support

PHP 5.4 is now fully supported, including traits and all the new syntax improvements: class member access on instantiation, short array syntax, array dereferencing on function call, binary literals, expressions in static calls, etc.:

PHP Code Sniffer

PhpStorm 4.0 allows you to check your code on the fly with PHP Code Sniffer (phpcs), just by opening a PHP file. The check is triggered every time you change something in the file, so it's extremely easy to fix problems reported by PHP Code Sniffer.

Visual PHP Debugger

The IDE provides numerous options for debugging your PHP code, so you can:

  • Inspect context-relevant local variables and user-defined watches, including arrays and complex objects, and edit values on the fly.
  • Setup remote debugging for your server.
  • Evaluate an expression in runtime.
  • Debug a page in multiple sessions simultaneously.
  • Keep a debugging session alive while moving between pages.

You can use our browser bookmarklets, Zend Toolbar or XDebug toolbar to initiate debugging directly from any page in a modern browser such as Firefox, IE, Google Chrome or Safari.

Rename refactoring works for files, functions, constants, classes, properties, methods, parameters, local and global variables. Make global project changes easily and safely. Local changes are made inplace.

PHP Unit Testing Support

Run/Debug PHPUnit tests right from code

Develop PHPUnit tests in Web IDE and run them instantly from directory, file or class using the context menu options.
