PHP Parser

Build Status Coverage Status

This is a PHP 5.2 to PHP 7.1 parser written in PHP. Its purpose is to simplify static code analysis and manipulation.

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:

echo 'Hi', 'World';
hello\world('foo', 'bar' . 'baz');

You'll get a syntax tree looking roughly like this:

    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).


The preferred installation method is composer:

php composer.phar require nikic/php-parser
