php delete folder (temporary file) code

Sometimes we need to delete the newly generated temporary files. For example, when uploading or generating images, we need to store them locally and then upload them to the image server. After the image is uploaded to the server, the locally stored image is useless. In order to avoid the project file being too large, it becomes necessary to delete the local image file.

Share a piece of code directly:

//需要传两个参数，一个是我们需要删除的文件路径，比如：
  $path2= "./upload/picture/";
      $this->delDirAndFile($path,true);
//这是删除的方法
  public function delDirAndFile($path, $delDir = true) {
     if (is_array($path)) {
       foreach ($path as $subPath)
         $this->delDirAndFile($subPath, $delDir);
     }
     if (is_dir($path)) {
       $handle = opendir($path);
       if ($handle) {
         while (false !== ( $item = readdir($handle) )) {
           if ($item != "." && $item != "..")
             is_dir("$path/$item") ?  $this->delDirAndFile("$path/$item", $delDir) : unlink("$path/$item");
         }
         closedir($handle);
         if ($delDir)
           return rmdir($path);
       }
     } else {
       if (file_exists($path)) {
         return unlink($path);
       } else {
         return FALSE;
       }
     }
     clearstatcache();
   }

The above will delete the code part of the folder or file. (By the way, the editor’s code color looks really ugly...)
