I am working on an Red Hat Enterprise Linux 5.x (but I do not have a license with Red Hat, so I cannot use 'yum'). I installed a new version of php on the server, but apache is still using the old version (without the features enabled that I need). How do I get apache to recognize the new php build? Do I rebuild apache? If so, how do i rebuild apache non-destructively in order to retain all of my current servers settings and files?
