How to force reload of configuration after modifying LocalSettings.php file in MediaWiki

I need to reload configuration after modifying LocalSettings.php without restarting Apache.

How is it possible?

Kind regards

If your LocalSettings.php is cached with opcache, you need to flush it. How it is done, is told here. In a nutshell:

• mod_php: apachectl graceful,
• php-fpm: service php-fpm reload,
• CGI or FastCGI: no need.

If you have APC: this answer.
