上面的代码有问题。
试试这个代码：

$get_url = "x.zip";
ob_end_clean();
header("Content-Type: application/force-download");
header("Content-Transfer-Encoding: binary");
header('Content-Type: application/zip');
header('Content-Disposition: attachment; filename='.'123_'.$get_url);
header('Content-Length: '.filesize($get_url));
error_reporting(0);
readfile($get_url);
flush();
ob_flush();
exit;
?>

我稍微修改了 一点儿，就可以正常下载。

你这个是IE下载设置的问题，不是程序的问题，设置IE就可以解决了
