A PHP implementation of the aaencode.
$ composer require jfcherng/php-aacodecAfter executing the following PHP code,
<?php
use Jfcherng\AaCodec\Codec;
require_once __DIR__ . '/../vendor/autoload.php';
$jsCode = 'alert("hello world");';
$encodingLevel = 0; // larger to get a longer encoded js code
$encoded = Codec::encode($jsCode, $encodingLevel);
file_put_contents('encoded.js', $encoded);
$decoded = Codec::decode($encoded);
file_put_contents('decoded.js', $decoded);encoded.js is now:
