How to make emacs fontify a php buffer

[Harry Putnam]

I want emacs to fontify a certain file... I think it is *.php but not
really sure.

Just adding .php to it does not seem to cause emacs to fontify that file.  Of
coure I have syntax hilighting turned on.

I've posted the file here:

Anyone recognize what kind of code it is?
Can anyone tell how to make emacs fontify that file?
