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

This library is distributed with npm :

npm install php-parser --save

// 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));

{
 '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/

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.

• AST nodes definition
• Sandbox
• List of options

• prettier/plugin-php : Prettier PHP Plugin
• babel-preset-php : Babel preset for converting PHP syntax to JavaScript. It can run subset of PHP in the browser or in Node.js
• wp-pot : Generate pot file for WordPress plugins and themes
• crane : PHP Intellisense/code-completion for VS Code
• php-unparser : Produce code that uses the style format recommended by PSR-1 and PSR-2.
