CentOS just builds whatever they release for as long as they release it. If they extend their lifetimes and continue to release the code, then we will continue to build and release it too. Also, the type of package you are talking about impacts the answer too. Please see the backporting blurb here: https://access.redhat.com/security/updates/backporting/ For Server type packages, like in your example php, the answer is that they almost always maintain the same Major/Minor version and just backport security fixes. But, for desktop applications, like OpenOffice, Firefox, Thunderbird, etc., they will move to newer items. As an example, CentOS 5.0 had firefox-1.5.0.9-10.el5.centos.src.rpm ... and now we have firefox-10.0.3-1.el5.centos.src.rpm. So some things, necessary for workstation type installs, will move ahead during the period. But server packages will generally maintain ABI/API compatibility (so basically php-5.3.x and httpd-2.2.x, etc will be maintained the whole time). Sometimes they will add new things on top of the old ... like when they added php53-5.3.x as well as php-5.1.9 to CentOS-5. Hopefully this answers your question.
