Question

我希望将强制下载功能添加到下面的文件exploere脚本中。我需要强制用户在单击$ namehref时下载文件，而不是在broswer中打开文件。我如何将其添加到代码中？

        <?php





        // Adds pretty filesizes
        function pretty_filesize($file) {
            $size = filesize($file);
            if ($size < 1024) {
                $size = $size . " Bytes";
            } elseif (($size < 1048576) && ($size > 1023)) {
                $size = round($size / 1024, 1) . " KB";
            } elseif (($size < 1073741824) && ($size > 1048575)) {
                $size = round($size / 1048576, 1) . " MB";

Answer 1

使用这一行：

header("Content-Disposition: attachment;Filename={FILE_NAME}");

因为它修改了标题信息，所以它应该放在所有echo s

之上

Answer 2

    header('Content-type: application/ms-excel');   // file type 
    header('Content-Description: File Transfer');
    header("Content-Disposition: attachment; filename=\"" .$filename . "\"");
    header("Cache-control: private");
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: no-cache');
