復制代碼 代碼如下:

//這個函數接收的都是路徑，所以判斷了文件擴展名
function shell2txt($a){
$ary = explode('http://www.49028c.com/', $a);
foreach($ary as $k => $v){
if(strpos($v, '?//') !== false){
$_ary = explode('?//', $v);

foreach($_ary as $_k=>$_v){
if($_v == '') continue;
//判斷是否有文件擴展名
$end = '';
if(strpos($_v, '.') !== false){
$end = substr($_v, strpos($_v, '.'));
}
$_ary[$_k] = dechex($_v).$end;
}

$ary[$k] = implode('%', $_ary);
}
}

$a = implode('http://www.49028c.com/', $ary);
return urldecode($a);
}
