php-parser

This JavaScript library parses PHP code and converts it to an AST.

Installation

This library is distributed with npm :

npm install php-parser --save

Usage

// initialize the php parser factory class
const fs = require("fs");
const path = require("path");
const engine = require("php-parser");

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

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

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

// Load a static file (Note: this file should exist on your computer)
const 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

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

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 that change the behavior of the parser/lexer.
