php-packer

A PHP version of Packer, JavaScript obfuscation library originally created by Dean Edwards, ported to PHP by Nicolas Martin. Packed for composer and slightly extended by Thomas Lutz.

Installation

Simply run composer require tholu/php-packer.

Usage (slightly changed from previous used implementation!)

<?php
require 'vendor/autoload.php';

$js = file_get_contents('test.js');

/*
 * params of the constructor :
 * $script:           the JavaScript to pack, string.
 * $encoding:         level of encoding, int or string :
 *                    0,10,62,95 or 'None', 'Numeric', 'Normal', 'High ASCII'.
 *                    default: 62 ('Normal').
 * $fastDecode:       include the fast decoder in the packed result, boolean.
 *                    default: true.
 * $specialChars:     if you have flagged your private and local variables
 *                    in the script, boolean.
 *                    default: false.
 * $removeSemicolons: whether to remove semicolons from the source script.
 *                    default: true.
 */

// $packer = new Tholu\Packer\Packer($script, $encoding, $fastDecode, $specialChars, $removeSemicolons);
$packer = new Tholu\Packer\Packer($js, 'Normal', true, false, true);
$packed_js = $packer->pack();
echo $packed_js;

UTF8

If you have UTF8 characters in your JavaScript like here, avoid using the "High ASCII" encoding and use "Normal" instead. Also make sure, that the file is saved and read with proper UTF8 encoding.
