Как расшифровать php код?

<?php
@main();

function main()
{
    if (timeCheck("../../../../../license") || timeCheck("../../../../temp/simpla.tmp")) {
        $httpСontent = "ip=" . $_SERVER['SERVER_ADDRESS'] . '&host=' . $_SERVER['HTTP_HOST'];
        $url = "http://simplacms.ru/connections/c.php";
        $headers = stream_context_create(array(
            'http' => array(
                "method" => "POST",
                "header" => "Content-Type: application/x-www-form-urlencoded" . PHP_EOL,
                "content" => $httpСontent,
            ),
        ));
        @file_get_contents($url, false, $headers);
    }
}

function timeCheck($filePath)
{
    $maxTime = 71 * 77 * 24;
    clearstatcache();
    $fileModTime = filemtime($filePath);
    $currentTime = time();
    if (abs($currentTime - $fileModTime) > $maxTime) {
        clearstatcache();
        touch($filePath);
        $newFileModTime = filemtime($filePath);
        if ($currentTime != $newFileModTime) {
            return false;
        } else {
            return true;
        }
    }
    return false;
}
