PHP是网站服务端最流行的编程语言之一。PHP运行环境本身是开源的，服务器不加载插件时PHP脚本也无法加密。但是，总有人因为商业上的考虑，而将PHP程序通过各种方法进行混淆，使读者很难看到清晰易懂的代码。

然而，PHP运行环境的本质决定了，被混淆、编码的PHP脚本总是有办法恢复成可读的代码的。本文介绍了一种对含有eval和base64_decode的、被加密的PHP的解码方法。

在使用这种方法之前，你应该准备好：

  • 能运行PHP的Web服务器，例如 Apache 或 IIS
  • wget.exe命令行客户端 或 浏览器
  • 具备PHP语法高亮功能的文本编辑器，例如 Notepad2

下载每一步的源代码

待解密的PHP代码来自某WordPress模板，来源

运行上述代码。运行的方法是：将代码粘贴到一个PHP文件里，用浏览器访问并查看源代码，或者用wget下载。运行结果是：

前后加上 <?php 和 ?> ，加进来原来$o的定义，并将代码稍稍排版一下，可得：

将代码中的第一个eval改成echo，后面的语句删除：

将运行结果替换掉echo(base64_decode(...))部分，后面的语句粘贴回来：

类似的，反复进行三步操作：

  1. 将eval替换成echo，删除后面的语句
  2. 运行
  3. 用运行结果替换eval语句，恢复后面的语句

直到代码中不再出现eval。

没有eval了！9r.php就是真实代码。从功能上看，也不妨把9.txt看作真实代码。

下载每一步的源代码

解码过程的关键是：

  • 每次只能处理一个eval()块
  • eval不能在循环、条件分支内部，否则不适用本方法
  • eval替换成echo后，必须把后面的代码删除
  • 获得运行结果后，用运行结果替换原来的eval，必须保留之前、之后的所有代码

PHP解密的难点，并不是技术问题，而是耐心。PHP解码，需要你作好打持久战的准备，才能顺利完成。

如果你正被形如eval(base64_decode(...))的PHP代码困扰，祝您在阅读本文后能顺利解密PHP代码。
