<p align="center">This javascript library parses PHP code and convert it to AST.</p>

Installation
------------

This library is distributed with [npm](https://www.npmjs.com/package/php-parser) :

```sh
npm install php-parser --save
```

Usage
-----

```js
// initialize the php parser factory class
var fs = require('fs');
var path = require('path');
var engine = require('php-parser');

// initialize a new parser instance
var parser = new engine({
  // some options :
  parser: {
    extractDoc: true,
    php7: true
  },
  ast: {
    withPositions: true
  }
});

// Retrieve the AST from the specified source
var eval = parser.parseEval('echo "Hello World";');

// Retrieve an array of tokens (same as php function token_get_all)
var tokens = parser.tokenGetAll('<?php echo "Hello World";');

// Load a static file (Note: this file should exist on your computer)
var phpFile = fs.readFileSync( './example.php' );

// Log out results
console.log( 'Eval parse:', eval );
console.log( 'Tokens parse:', tokens );
console.log( 'File parse:', parser.parseCode(phpFile) );

```

Sample AST output
-----------------

```js
{
  'kind': 'program',
  'children': [
    {
      'kind': 'echo',
      'arguments': [
        {
          'kind': 'string',
          'isDoubleQuote': true,
          'value': 'Hello World'
        }
      ]
    }
  ]
}
```

- Try it online (demo) : http://glayzzle.com/php-parser/
- Or from AST Explorer : https://astexplorer.net/


API Overview
------------

The main API exposes a class with the following methods :

- **parseEval**(String|Buffer) : parse a PHP code in eval style mode (without php open tags)
- **parseCode**(String|Buffer, String filename) : parse a PHP code by using php open tags.
- **tokenGetAll**(String|Buffer) : retrieves a list of all tokens from the specified input.

You can also [pass options](https://github.com/glayzzle/php-parser/wiki/Options) that change the behavior of the parser/lexer.
