JetBrains PhpStorm is a commercial, cross-platform IDE for PHP built on JetBrains' IntelliJ IDEA platform.
PhpStorm provides an editor for PHP, HTML and JavaScript with on-the-fly code analysis, error prevention and automated refactorings for PHP and JavaScript code. PhpStorm's code completion supports PHP 5.3, 5.4, 5.5, 5.6 & 7.0 (modern and legacy projects), including generators, coroutines, the finally keyword, list in foreach, namespaces, closures, traits and short array syntax. It includes a full-fledged SQL editor with editable query results.
PhpStorm is built on IntelliJ IDEA, which is written in Java. Users can extend the IDE by installing plugins created for the IntelliJ Platform or write their own plugins.
All features available in WebStorm are included in PhpStorm, which adds support for PHP and databases. WebStorm ships with pre-installed JavaScript plugins (such as for Node.js), which are available for PhpStorm as well at no cost.
PhpStorm provides a rich code editor for PHP with syntax highlighting, extended code formatting configuration, on-the-fly error checking, and code completion.
PHP 5.3, 5.4, 5.5, 5.6, 7.0, 7.1 support, including generators, coroutines, the finally keyword, list in foreach, using empty() on the result of function calls and other expressions, traits, closures, class member access on instantiation, short array syntax, array dereferencing on function call, binary literals, expressions in static calls, it supports return types and scalar type hints and constant visibility, etc. It can be used for both modern and legacy PHP-based projects.
Code autocompletion finalizes classes, methods, variable names, and PHP keywords, plus commonly used names for fields and variables depending on their type.

Local History (tracks any changes in the code locally).
PHP UML (UML class diagrams for PHP code with refactorings invoked right from the diagram).
Phing support (autocompletion, checks standard tags, properties, target names, path attribute values in build files).
Issue tracker integration.
Support for Vagrant, SSH console & remote tools
Google App Engine for PHP Support
Debugging and testing
Easy-to-configure visual debugger (Xdebug, Zend Debugger) for inspecting context-relevant local variables and user-defined watches, including arrays and complex objects, and editing values on the fly.
Scripts can be profiled right from PhpStorm with either XDebug or Zend Debugger. An aggregated report is available, and the user can jump from the execution statistics directly to the function in PHP code.
PHPUnit tests can be developed in PhpStorm and run instantly from a directory, file or class using the context menu options) with code coverage.
JavaScript, CSS and HTML features

Licensing and updates policy
In November 2015 JetBrains switched to licensing PhpStorm on a subscription basis. Annual subscriptions, or monthly subscriptions maintained for 12 consecutive months also receive a "perpetual fallback license" to the major version available at time of purchase. PhpStorm is available for individual developers, and business and organisations. Additional discounted and complimentary licenses are available for startups, students and teachers, and non-commercial open source projects. These complimentary licenses require approval and do not include the perpetual fallback clause, i.e. they expire.
