php递归遍历删除文件

php递归遍历删除文件，这个函数稍加修改就可以变成一个递归文件拷贝函数

<? 
function mover($src,$dst) { 
$handle=opendir($src);                      // Opens source dir. 
if (!is_dir($dst)) mkdir($dst,0755);       // Make dest dir. 
while ($file = readdir($handle)) { 
    if (($file!=".") and ($file!="..")) {       // Skips . and .. dirs 
        $srcm=$src."/".$file; 
        $dstm=$dst."/".$file; 
       if (is_dir($srcm)) {                      // If another dir is found 
          mover($srcm,$dstm);               // calls itself - recursive WTG 
       } else { 
          copy($srcm,$dstm); 
          unlink($srcm);                         // Is just a copy procedure is needed 
       }                                             // comment out this line 
    } 
} 
closedir($handle); 
rmdir($src);                                     // and this one also :) 
} 
?>
