WordPress提供了一个名为unzip_file()-- 在Google中键入“wordpress unzip”即可轻松找到。法典中有示例代码：

WP_Filesystem();
$destination = wp_upload_dir();
$destination_path = $destination[\'path\'];
$unzipfile = unzip_file( $destination_path.\'/filename.zip\', $destination_path);

if ( $unzipfile ) {
  echo \'Successfully unzipped the file!\';       
} else {
  echo \'There was an error unzipping the file.\';       
}
