GitHub - glayzzle/php-parser: 🌿 NodeJS PHP Parser - extract AST or tokens (original) (raw)

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' } ] } ] }

• 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 that change the behavior of the parser/lexer.
