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));
