This javascript library parses PHP code and convert it to AST.
This library is distributed with npm :
npm install php-parser --save
// 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) );
{ '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.
