PHP脚本可以欺骗浏览器认为HTTP请求结束了吗？ [英] Can a PHP script trick the browser into thinking the HTTP request is over?

问题描述

我首先将脚本配置为在HTTP请求结束后运行

I first configure my script to run even after the HTTP request is over

 ignore_user_abort(true);

然后清除一些文字。

 echo "Thats all folks!";
 flush();

现在我怎么欺骗浏览器认为HTTP请求结束了？所以我可以继续做自己的工作，而浏览器没有显示页面加载。

Now how can I trick the browser into thinking the HTTP request is over? so I can continue doing my own work without the browser showing "page loading".

 header(??) // something like this?

推荐答案

以下是如何操作的。您告诉浏览器读取输出的前N个字符，然后关闭连接，同时脚本一直运行直到完成。

Here's how to do it. You tell the browser to read in the first N characters of output and then close the connection, while your script keeps running until it's done.

<?php
ob_end_clean();
header("Connection: close");
ignore_user_abort(true); // optional
ob_start();
echo ('Text the user will see');
$size = ob_get_length();
header("Content-Length: $size");
ob_end_flush();     // Will not work
flush();            // Unless both are called !

// At this point, the browser has closed connection to the web server

// Do processing here
echo('Text user will never see');
?>
