Can I increase Apache's TimeOut directive for specific PHP script?

Question

I have a PHP script that will be executed by requests from the application admins. It does lots of stuff and takes at least 20 minutes(depending on the database size)

the Apache TimeOut directive is set to 300(5 minutes) which closes the connection and returns 500 status code after my PHP script is finished if it takes longer time to execute

Setting the PHP ini max_execution_time for long time for this script is useless.

<?php
// long script
ini_set("max_execution_time", 3600);// 1 hour
// Apache still responses with the same "Connection: close" header and 500 status code

And I don't want to change the entire Apache TimeOut directive just for those couple of scripts, because if I did, any request will be able to take very long time which makes a scope for DDOS vulnerabilities, is this right?

Is there any way to allow this script only to run longer at the Apache level ?

@rkosegi thank you for the helpful answer in the link, but as I mentioned I can't set the entire server timeout for 1 hour for any request, I only want this specific script to be allowed for longer execution times. — Accountant م

The Timeout directive cannot be configured in .htaccess. Its scope is server configuration and virtual host configuration (httpd.apache.org/docs/2.4/mod/core.html#timeout). Also the error you are getting may not be related to the Timeout directive. Please post the contents of your Apache error log file — Nadir Latif

Can you try to enable the error reporting in your php script. You can do this by adding the lines: error_reporting(E_ALL); ini_set("display_errors", '1'); to the top of your php script — Nadir Latif

Have you tried PHP's set_time_limit() method?

https://www.php.net/manual/en/function.set-time-limit.php

In addition to setting the initial execution time, the manual says that calling it resets the time expended to zero when called, and starts the counter again to the limit provided.

So if you want to be sure, you could just call set_time_limit(0) (0 == no limit) regularly throughout your script to make sure that you don't ever hit a limit (even though you're setting an infinite limit by passing in 0).
