emacs php customization

Hi guys! I'm trying to get PHP syntax highlighting for GNU-emacs 21.1.1 (SuSE 8.0) to work. I found some html stuff and was able to get it to work. But if I have a file *.php it doesnt work. I found some html-helper-mode (via 10000 links on GNU.ORG) that supposingly gets php highlights also, but I can't get it to work... Anybody have any ideas/suggestions/tips? Thanks!!! Later HG
