解决php接收shell返回的结果中文乱码问题_PHP

//这个函数接收的都是路径，所以判断了文件扩展名 
function shell2txt($a){ 
$ary = explode('/', $a); 
foreach($ary as $k => $v){ 
if(strpos($v, '?\\') !== false){ 
$_ary = explode('?\\', $v); 

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

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

$a = implode('/', $ary); 
return urldecode($a); 
}
