You can use any of the apache mods e.g. mod_auth_openidc or mod_mellon . These mods are agnostic to any programming language/platform and keycloak has a very good support for them.

The PHP is running over a simple Apache HTTPD, therefore we cannot use any of the Out Of The Box client adapters available for Keycloak. What should we do in this case? Is there any documentation or guide that we should follow?
