for virtual servers, there is Resource Limit features for PHP settings. There is Default option to choose instead of typing memory limit and upload etc. I changed it to Default, for example memory_limit, then I can see it's 128M in phpinfo(). But I want to set a limit for default value, where should I change it? I tried /etc/php.ini, /opt/rh/rh-php72/register.content/etc/opt/rh/rh-php72/php.ini , and /etc/opt/rh/rh-php72/php.ini. It doesn't work. I just want to limit the virtual server owners from exceeding my limit.
