RPM Installation Did Not Install PHP Modules

I installed PHP/Apache/MySQL via the Red Hat installation process (7.2), but Apache isn't processing PHP files, they show up as plain text in the browser. I checked with the FAQ and related documentation which said to ensure that the AddModule and LoadModule directives where there and not commented out. They are there, although they are within <IfDefine HAVE_PHP> tags. When I followed the path the modules are supposed to be in (modules/mod_php.so for example), I discovered there were no php modules in /etc/httpd/modules, nor any other place on my system (after a find...). Why were these modules not installed? What should I do? I tried to build from the source, but then I got some error after ./configure that says lex command not found. What's lex?
