[经验求助] 分析一个php加密方法，想知道是什么加密的，如何解密

前两天在某破解看到此贴，想试着解，但是奈何本人技术较差无法还原，想求助佬提供思路

以下内容来自52pojie，仅研究算法解密！

基本思路：

• 使用PHP解析器，将PHP代码解析成抽象语法树(AST)
• 梯度遍历AST,根据预定义的规则修改节点
• 修改变量名和函数名
• 内联字符串调用
• 合并字符串
• 删除无用代码
• 格式化代码
• 从修改后的AST重新生成PHP代码
• PHP代码后的输出反混淆
• 关键点是解析出AST，并定义修改AST的规则

思路就这些，但是想要批量还原的话，目前没有看到这些库，又没有可以直接解的方法，ai工具都有试过，可能是我询问的方法问题，并没有给出相对应的解法

加密前：

<?php
namespace app\api\controller\v6;
class Update extends Base
{
    public function Index()
    {
        require_once 'apk/v16.php';
        $vsdata = get_url_up();
        $data = array('code' => $vsdata['code'], 'msg' => 'success', 'url' => $vsdata['url']);
        die(json_encode($data));
    }
}

加密后：

<?php
namespace app\api\controller\v6;
 
if (!defined("A_AA_AAAAAA_AAA__")) {
    define("A_AA_AAAAAA_AAA__", "A_AA_AAAAAA_AAA_A");
}

if (!defined("A_AA_AAAAAA_A___A")) {
    define("A_AA_AAAAAA_A___A", "A_AA_AAAAAA_A__A_");
}
$GLOBALS[A_AA_AAAAAA_A___A] = explode("|r|y||", "H*|r|y||61706B2F7631362E706870|r|y||636F6465|r|y||6D7367|r|y||73756363657373|r|y||75726C");
if (!defined(pack($GLOBALS[A_AA_AAAAAA_AAA__][0], $GLOBALS[A_AA_AAAAAA_AAA__][1]))) {
