I'm unhappy with the default coloring scheme in vim and would like to change it. I tried to follow the accepted answer on [this page][1], but I think my vim version (7.4) is different. 

Inside `/usr/share/vim/vim74/syntax` I have tons of files, so I decided to edit `php.vim`. But I find that the format in the file isn't like the one in the link I mentioned. Here's my [php.vim][2] file. 

Can someone help me figure out how to customize vi syntax highlighting?
