PHP文件下载脚本不适用于iOS7设备吗? [英] php file download script doesn't work with iOS7 device?

问题描述

我有以下php脚本来触发自动下载.

I have the follow php script to trigger auto downlad.

<?php
    ob_start();

    $file = 'sample.jpg';

    if (file_exists($file)) {
        header('Content-Description: File Transfer');
        header('Content-Type:  application/octet-stream');
        header('Content-Disposition: attachment; filename='.basename($file));
        header('Content-Transfer-Encoding: binary');
        header('Expires: 0');
        header('Cache-Control: must-revalidate');
        header('Pragma: public');
        header('Content-Length: ' . filesize($file));
        ob_clean();
        flush();
        readfile($file);
        exit;
    }
?>

它可以在台式机和Android手机上正常运行，但不能在iPad和iPhone上正常运行.

it works properly on desktop and my android phone, but not on my iPad and iPhone.

我应该怎么做才能使其在iPad&iPhone?

what should I do to get it works on iPad & iphone?

谢谢.

推荐答案

尝试注释掉设置Content-Length的行，如下所示:

Try commenting out the line where you set the Content-Length, like this:

    //header('Content-Length: ' . filesize($file));

...我没有更深入地研究，但现在在iPad iOS 7.0.4上对我来说有效

... I haven't dug deeper but right now that's working for me on iPad iOS 7.0.4
