php-parser

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

Installation

This library is distributed with npm :

``sh
npm install php-parser --save
`

Usage

`js
// 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('

// 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

`js
{
'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.
