这成为我的解决方案，来自HamZa的提示（谢谢！）
我创建了一个脚本，它遍历选择的目录（在 中指定$dir）
我们还可以通过以下方式说出我们在文件中要查找的内容$lookFor
我在代码中添加了一些注释，因此您可以按照我的操作进行操作。这不会解决function-db 的问题。
因此，如果您有带有 DB 连接的类，则必须为函数添加一些东西。
现在这个脚本不会改变你的文件（我把它注释掉了，所以你可以用它来浏览你的代码和“推荐”的改变）
而且..我还没有做到，所以脚本准备了语句。
（这是第二步，这只是为了修复mysql_*被移除时会损坏的东西）
结果将如下所示：（实际上显示了我谈到的缺少的功能..我必须添加global $__db;到每个function
然后终于！这是代码。
