如何在php中制作下载脚本[关闭]

You need to set up headers properly then print the file contents.

You need to get the mime type and file size, then set the correct headers before sending the file. Try this:

function sendFile($file) {
    $finfo = finfo_open(FILEINFO_MIME_TYPE);
    header('Content-type: ' . finfo_file($finfo, $file));
    header('Content-length: ' . filesize($file));
    $filename = basename($file);
    header("Content-Disposition: attachment; filename='$filename'");
    fpassthru($file);
    finfo_close($finfo);
}
