PHP Code Editor

Intelligent Code Editor

PhpStorm features a rich and intelligent code editor for PHP that actually "gets" your code and deeply understands its structure, supporting PHP 5.3, 5.4, 5.5, 5.6, 7.0, 7.1 for modern and legacy projects. The IDE provides smart code completion, syntax highlighting, extended code formatting configuration, on-the-fly error checking, code folding, supports language mixtures and more.

Language Features Support

The latest PHP 7 is supported including support of anonymous classes, return type declarations, null coalesce operator, group use declarations, context sensitive lexer, and more. PHP 7.1 compatibility inspections will help update your project to the latest PHP version. PHP 5.3, 5.4, 5.5, 5.6, and 7.0 are supported as well.

PHP Refactoring

The Rename and Move refactorings work for files, functions, constants, classes, properties, methods, parameters, and local and global variables. Make global project changes easily and safely. Local changes are made instantly in-place.

The following refactorings are also available: Extract Variable / Constant / Field / Method / Interface, Inline variable, Push members Up / Pull members Down, Change signature, Move class to another namespace, Move static member, Make Static refactoring.

Code Completion

Automatic code completion (invoked on typing) finalizes classes, methods, variable names, and PHP keywords, plus commonly used names for fields and variables depending on their type. Code completion also supports array indexes in PHP code.

Code Formatting

Code formatter with code style configuration and other features help you write neat code that's easy to maintain. PhpStorm contains built-in code formatting that is compliant with PSR1/PSR2, Symfony2, Zend, Drupal & other standards.

Code (Re)arranger

Code (re)arranger is a powerful tool to control the structure of your existing and generated code. For example, you can specify methods to be ordered after fields or keep dependent methods together.

PHPDoc Support

PhpStorm editor respects PHPDoc in your code and provides appropriate code completion suggestions based on annotations. When you edit PHPDoc for your code, variable names and types are auto-completed from the corresponding code blocks. PHP code refactorings also consider PHPDocs to keep them up to date.

Parameter Hints

With Parameter hints in PhpStorm, code becomes more readable and easier to understand. Parameter hints are showed for literals and nulls used as method arguments, helping you better understand the semantics of specific methods.

Code Quality Analysis

Hundreds of code inspections verify your code as you type and inspect the whole project for possible errors or code smells.

Quick-fixes for most inspections make it easy to fix or improve the code instantly. Alt+Enter shows appropriate options for each inspection.

PHP Code Sniffer & Mess Detector

Check your code on the fly with PHP Code Sniffer (phpcs) and PHP Mess Detector (phpmd), 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 & PHP Mess Detector.

Twig, Blade & Smarty Templates

Use the Twig, Blade or Smarty template engine to take advantage of productivity features when working with template files: configurable syntax highlighting for different constructs; syntax errors highlighting; functions and attributes completion; automatic insertion of paired braces, quotes and closing tags; and more.

Phar Packages

PhpStorm transparently recognizes Phar-packaged code.

Smart Duplicated Code Detector

Added for all major supported languages including PHP, HTML and CSS. Use Code | Locate Duplicates to start your quest against copy/paste coding. You'll be presented with a list of candidates for refactoring — and with the help of refactorings it's easy to keep your code DRY.

Callback References

Code editor understands callback references within string literals, and provides advanced assistance such as usages search and rename refactoring.


PhpStorm provides smart handling of namespaces, with Auto-Import, Optimize Imports, folding for imports, and more.

Efficient Project Analysis and Navigation

Its thorough source code analysis allows PhpStorm to provide sophisticated code completion even for unannotated code, for example when the function return type is deducted from its body and return statements or class property types (and declarations) are extracted from the constructor code.

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

Dataflow Analysis

Dataflow Analysis helps you understand you project code better, interpret complicated parts of code, find bottlenecks in the source code, and more.

Easy Code Navigation & Search

Go to class / file / symbol — crucial operations for fast project navigation. Use wild-cards and abbreviations to locate needed items faster.

Go to declaration — navigates to where the function, variable or label in question is declared with a simple hotkey or Ctrl+Click / ⌘Click.

Find Usages — helps you locate usages of any symbol (e.g., class, method, field, etc.) in your code, in the current file or in the whole project.
