As these are shared between Php5 and Php7 parsers they should be
in some common place, otherwise we'd have to always reference either
one or the other.

PHP Parser

This is a PHP 5.2 to PHP 5.6 parser written in PHP. Its purpose is to simplify static code analysis and manipulation.

Documentation for version 1.x (stable; for running on PHP >= 5.3).

Documentation for version 2.x-dev (dev; for running on PHP >= 5.4).

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

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

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).
