我没有得到任何解决方案，所以在这里尝试问一下，也许有人可以指出我，为什么下面的这个脚本在 NGINX + php5.3.21 上不起作用，但在 apache + php5.2.17 上工作正常，也许它在 php.ini 中还是我在 nginx.conf 中遗漏了什么？

它应该强制标头下载文件并跟踪它是否被取消或完成，然后做一些事情。

为了让它开始在 nginx 中下载，我必须取消注释 last flush(); 但如果取消或完成，它仍然不会跟踪文件“进度”。阿帕奇很好:((谢谢！

<?php
$FOLDER_PROGRESS = 'progress/';
$FOLDER_FILES = 'files/';

switch($_REQUEST['acc']){

case 'download':

    $file = trim($_REQUEST['n']);

    if(!file_exists($FOLDER_FILES.$file)){
        echo '<script>alert("Error: The file do not exists.");</script>';
    } else {
        $continue = 'OK';
    }

    if($continue=='OK'){

        $result = fopen($FOLDER_FILES.$file,'r');
        $bytes = filesize($FOLDER_FILES.$file);

        if($bytes<1){
            //header('Location: /');
            echo '<script>alert("Error: The file bytes length is 0.");</script>';
        } else {

            $fp1 = fopen($FOLDER_PROGRESS.trim($_REQUEST['tmp']).'.html','w');
            fwrite($fp1,'Downloading');

php 工作正常， phpinfo() 返回所有正面信息。nginx.conf

和 mysite.conf

            error_log /var/log/nginx/mysite.error_log;

            root /var/www/www.mysite.com;
            index index.php index.htm index.html;

            location ~ \.php$ {
              fastcgi_pass   127.0.0.1:9000;
              fastcgi_index  index.php;
              fastcgi_param  SCRIPT_FILENAME /var/www/www.mysite.com$fastcgi_script_name;
              include fastcgi_params;
            }

   }

解决了！一切都在进行 fastcgi 设置！FastCGI 在完成处理之前不会向客户端输出缓冲区；所以像flush这样的东西是“未知的”。对于其他有同样问题的人：您需要设置以下设置

 fastcgi_keep_conn on;
 fastcgi_read_timeout 600;
 fastcgi_buffer_size 1k;
 fastcgi_buffers 128 1k;
 fastcgi_max_temp_file_size 0;
 gzip off;
