PHP 脚本能否诱使浏览器认为 HTTP 请求已结束?
我首先将脚本配置为即使在 HTTP 请求结束后也能运行
I first configure my script to run even after the HTTP request is over
ignore_user_abort(true);
然后刷新一些文本.
echo "Thats all folks!";
flush();
现在我怎样才能让浏览器认为 HTTP 请求已经结束?这样我就可以在浏览器不显示页面加载"的情况下继续做自己的工作.
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
以下是操作方法.您告诉浏览器读取输出的前 N 个字符，然后关闭连接，同时您的脚本继续运行直到完成.
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');
?>
