Generate title tags using php

hi , i am looking for someone to implement some simple php code so that the and other meta tags can be generated depending on what page it is. At the momment , i only have one title tag and meta tag for every page on the site [login to view URL] i have done some research and it is possible for the to be generated by php according to what i set it. So each page would have a different set of tags especially title tag . I need to do this asap for SEO reasons.
