problem with vim!

I'm having a major issue with vim. I'm using v6.4 I believe.
 The problem is... with my old version of vim, when I edited .php files....
it would auto-indent html elements, so that it looked something like...
 <html>
 <head>
 <title>
  etc. and it would line up all the closing elements automatically. now
however... it will not do this when I edit php files! it will do it for html
files though.
 So my question is how do I resolve this? In essence, I guess what I would
like is for .php files to have same indent / color / etc as .html, along
with also having indents / color / etc for .php files.
 Any help is very much appreciated!
