Its purpose is to simplify static code analysis and +manipulation. + +[**Documentation for version 3.x**][doc_master] (stable; for running on PHP >= 5.5; for parsing PHP 5.2 to PHP 7.1). + +[Documentation for version 2.x][doc_2_x] (stable; for running on PHP >= 5.4; for parsing PHP 5.2 to PHP 7.0). + +[Documentation for version 1.x][doc_1_x] (unsupported; for running on PHP >= 5.3; for parsing PHP 5.2 to PHP 5.6). + +In a Nutshell +------------- + +The parser turns PHP source code into an abstract syntax tree. For example, if you pass the following code into the +parser: + +```php +<?php +echo 'Hi', 'World'; +hello\world('foo', 'bar' . 'baz'); +``` + +You'll get a syntax tree looking roughly like this: + +```php +array( + 0: Stmt_Echo( + exprs: array( + 0: Scalar_String( + value: Hi + ) + 1: Scalar_String( + value: World + ) + ) + ) + 1: Expr_FuncCall( + name: Name( + parts: array( + 0: hello + 1: world + ) + ) + args: array( + 0: Arg( + value: Scalar_String( + value: foo + ) + byRef: false + ) + 1: Arg( + value: Expr_Concat( + left: Scalar_String( + value: bar + ) + right: Scalar_String( + value: baz + ) + ) + byRef: false + ) + ) + ) +) +``` + +You can then work with this syntax tree, for example to statically analyze the code (e.g. to find +programming errors or security issues). + +Additionally, you can convert a syntax tree back to PHP code. This allows you to do code preprocessing +(like automatedly porting code to older PHP versions). + +Installation +------------ + +The preferred installation method is [composer](https://getcomposer.org): + + php composer.phar require nikic/php-parser + +Documentation +------------- + + 1.
