PHP实现递归复制整个文件夹的类实例

<"." && $f1!=".."){
      $path2="{$fromFile}/{$f1}";
      if(is_file($path2)){  
        $file = $path2;
        $newfile = "{$toFile}/{$f1}";
        copy($file, $newfile);
      }elseif(is_dir($path2)){
        $toFiles = $toFile.'/'.$f1;
        $this->copyFile($path2,$toFiles);
      }
    }
  }
}
/*
 * 递归创建文件夹
 */
function CreateFolder($dir, $mode = 0777){
  if (is_dir($dir) || @mkdir($dir,$mode)){
    return true;
  }  
 if (!$this->CreateFolder(dirname($dir),$mode)){
   return false;
 }
  return @mkdir($dir, $mode);
}
}
//使用方法
//引入本类，直接new copyFile('要复制谁','复制到那');
//$file = new CopyFile('aaaa/aaaaa','bbbbb/bbbb');
?>
