clarkwinkelmann cokavar I'm not familiar with OpenLiteSpeed, but I don't know of any webserver that has PHP built-in. Usually you always need the PHP packages plus the webserver packages on the server. Or are you thinking of PHP-FPM?
rafaucau https://docs.openlitespeed.org/config/php/ Or if you are using the official Docker image (https://hub.docker.com/r/litespeedtech/openlitespeed/tags), it comes with PHP installed.
Nodeloc When you install OLS, LSPHP will install automatically. You can also compile your own PHP version in OLS CP.
