php returns directly without waiting for the result

Sometimes we request a php just to trigger an event, but not Regardless of the execution time and results, you need to immediately return a message to the browser and disconnect, for example, return: The task has started! How to achieve this? You can use fastcgi_finish_request() to disconnect from the browser. The specific implementation is as follows:

<?php
echo "这个是输出到浏览器的内容";
// =======这部分是将输出内容刷新到用户浏览器并断开和浏览器的连接=====
// 如果使用的是php-fpm
if(function_exists(&#39;fastcgi_finish_request&#39;)){
    // 刷新buffer
    ob_flush();
    flush();
    // 断开浏览器连接
    fastcgi_finish_request();
}
// 后台继续执行任务
sleep(2);
file_put_contents(&#39;/tmp/test.log&#39;, &#39;ok&#39;);
