Multiple PHP version (self-compiled) on CentOS 6

I currently have 2 installations of PHP following your guide on how to install PHP 5.4 next to 5.3, which is great and all. Only problem is, those binaries are missing some features which I want compiled in, so I compiled my own new PHP version into /opt/php/5.4.23/ but I’m not exactly sure how to set up my one virtual host to use it.
Is it even possible?
