To find out what this does, use a text editor and command-line php. Extract individual strings and throw them at PHP to de-obfuscate them (just be careful not to eval() them before you know what that would do). This part, for example:

要了解它的用途，请使用文本编辑器和命令行php。提取单独的字符串并将它们扔到PHP中去混淆它们(只是要注意不要在你知道它会做什么之前)。这一部分,例如:

$eva1tYldakBcVSir = "\x73\164\x72\162\x65\166";

...evaluates to 'strrev'.

…计算结果为“strrev”。

Once you've deciphered the 'safe' parts (those parts that merely assign string values to variables), you probably have an idea what the rest does. One of the other strings, for example, is 'edolpxe'; combine that with strrev and you have explode. I haven't followed this all the way through, but if you do, you'll be able to make some sense of it.

一旦您破译了“安全”部分(那些仅仅将字符串值赋给变量的部分)，您可能已经知道其余部分的功能了。例如，另一个字符串是“edolpxe”;把它和strrev结合，你就会爆炸。我并没有一直这么做，但是如果你这么做了，你就能对它有所了解了。

In any case, take your site down until you have sorted it all out, and make sure you have a backup somewhere (ideally an uncompromised one). If you're on shared hosting, you'll also want to inform your hosting provider, in case this thing can spread to other sites on the same server.

无论如何，把你的网站删除，直到你把它整理好，并确保你在某个地方有一个备份(最好是一个不妥协的备份)。如果您在共享主机上，您还需要通知您的主机提供商，以防这一事件可以传播到同一服务器上的其他站点。
