Drupal 7 drupal 7无法在ArchiverZip中打开->__建造

我用这段代码来解压缩zip文件

$file = "/sites/default/files/xml_files/file.zip";
$obj = new ArchiverZip($file);

但会抛出此错误：

Exception: Cannot open <em class="placeholder">/sites/default/files/xml_files/file.zip</em> in ArchiverZip->__construct()

但它抛出了相同的异常

有什么想法吗？ 谢谢

尝试使用以下方法：

$archive_file = 'public://xml_files/file.zip'
$directory = 'temporary:///extracted_files'    
$archiver = archiver_get_archiver($archive_file);
$archiver->extract($directory);

$archive_file = 'public://xml_files/file.zip'
$directory = 'temporary:///extracted_files'    
$archiver = archiver_get_archiver($archive_file);
$archiver->extract($directory);
