 if(!is_dir($dirname)){
  echo "{$dirname}不是一个有效的目录!";
  exit();
 }
 $handle = opendir($dirname);

 while(($fn = readdir($handle))!==false){

  if($fn!=&#39;.&#39;&&$fn!=&#39;..&#39;){
      echo "<br>将名为:".$fn."\n\r";
      $curDir = $dirname.&#39;/&#39;.$fn;
   if(is_dir($curDir)){
      fRename($curDir);
   }else{
      $path = pathinfo($curDir);
      //改成你自己想要的新名字

      echo "替换成:".$i.&#39;.&#39;.$path[&#39;extension&#39;]."\r\n";
      rename($curDir,$newname);
