复制代码 代码如下:

//delfile("upload",10);
function delfile($dir,$n) //删除当DIR路径下N分钟前创建的所有文件;
{
if(is_dir($dir))
  {
 if($dh=opendir($dir))
   {
    while (false !== ($file = readdir($dh)))
    {
     if($file!="." && $file!="..")     
      {
       $fullpath=$dir."/".$file;
       if(!is_dir($fullpath))
       {
        //$filedate=date("Y-m-d", filemtime($fullpath));    
        $filedate=date("Y-m-d h:i:s", filemtime($fullpath));
  //$d1=strtotime(date("Y-m-d"));
        $d1=strtotime(date("Y-m-d h:i:s"));
        $d2=strtotime($filedate);
        //$Days=round(($d1-$d2)/3600/24);
        $Days=round(($d1-$d2)/60);   
        if($Days>$n)
        unlink($fullpath);  ////删除文件

         }
     }     
    }
   }
   closedir($dh);
