    天亮了,放弃了。谁有耐心谁解吧。
    谁能翻译这个?在容错条件下执行
    array('\14',', $',') { ','[$i]','substr($','a = $xx("|","',',strpos($y,"9")',' = str_replace($','x3','\x7','\15',';$i++) {','function ','x6','); ','for($i=0;$i';

    首先,你得先格式化,之后的样子如同4楼的样子
    然后,跟着程序逻辑走下去,分析它每步操作后的结果是什么,结果如同4楼的注释一样

    @touch 纯手工,查找分号或者字符串结尾引号,然后分成一句一句,然后每句输出

    感谢各位为小弟分忧哇,应该是空间的问题的,我空间里所有php开头都加上了这段代码
    如果是被挂马的话,应该不会这么明显
    下面是一个文件的源代码

    才发现v2ex的楼层计数那个位置是从右边定位的?
    现在gist过宽的问题这么频繁了,也差不多该改成从左边定位了吧?

    应该是被挂马的,而且都是在PHP文件第一行挂上去的。貌似WP比较容易被这种简单的挂马程序击中。
