How to continue processing after PHP access ends

Today I saw someone in dewen asking how to use php to continue executing the subsequent code after the browser access is completed, I wrote a demo, it is very easy to implement in the php-fpm environment, fastcgi_finish_request is enough. If it is another container, I think the jump can only be achieved by outputting javascript to the client, and then continuing execution in the background.

The demo is as follows, php-fpm test is available, apache php-cgi is not tested because there is no environment. (Recommended learning: PHP video tutorial)

<?php
// 你要跳转的url
$url = "http://www.baidu.com/";
 
// 如果使用的是php-fpm
if(function_exists(&#39;fastcgi_finish_request&#39;)){
    header("Location: $url");
    ob_flush();
    flush();
    fastcgi_finish_request();
// Apache ?
}else{
    header( &#39;Content-type: text/html; charset=utf-8&#39; );
    if(function_exists(&#39;apache_setenv&#39;))apache_setenv(&#39;no-gzip&#39;, &#39;1&#39;);
    ini_set(&#39;zlib.output_compression&#39;, 0);
    ini_set(&#39;implicit_flush&#39;, 1);
    echo "<script>location=&#39;$url&#39;</script>";
    ob_flush();
    flush();
}
 
    // 这里是模拟你的耗时逻辑
    sleep(2);
    file_put_contents(&#39;/tmp/test.log&#39;, &#39;ok&#39;);
