PHP code

$code = '解密代码'; // 你的txt的内容全部粘贴过来

do {

    $code = str_replace('eval', '$code =', $code);
    try{
        eval($code);
    } catch (Exception $e) {
        echo 'errro : ' . $code;
        echo $e->getMessage();
        break;
    }

    $code = trim($code, '?php');
// 这里也可以用 strpos($code, 'eval')
}while(substr(trim($code), 0, 4) == 'eval');

echo $code; <div class="clear">
                 
              
              
        
            </div>
