PHP更快的提供文件下载

我们可以使用Apache的module mod_xsendfile, 让Apache直接发送这个文件给用户

1. $file = "/tmp/中文名.tar.gz";
    
       $filename = basename($file);
    
       header("Content-type: application/octet-stream");
    
       //处理中文文件名
       $ua = $_SERVER["HTTP_USER_AGENT"];
       $encoded_filename = urlencode($filename);
       $encoded_filename = str_replace("+", "%20", $encoded_filename);
       if (preg_match("/MSIE/", $ua)) {
        header('Content-Disposition: attachment; filename="' . $encoded_filename . '"');
       } else if (preg_match("/Firefox/", $ua)) {
        header("Content-Disposition: attachment; filename*=\"utf8''" . $filename . '"');
       } else {
        header('Content-Disposition: attachment; filename="' . $filename . '"');
       }
    
       header('Content-Disposition: attachment; filename="' . basename($file) . '"');
    
       //让Xsendfile发送文件
       header("X-Sendfile: $file");

X-Sendfile头将被Apache处理, 并且把响应的文件直接发送给Client.
