推荐答案

下面是如何做到这一点。你告诉浏览器输出的前N个字符阅读，然后关闭连接，而你的脚本继续工作，直到它完成。

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(); // 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
include('other_script.php');

echo('Text user will never see');
?>
