Q:

PHP Vim autocomplete

I can not get the autocomplete to work for php files. I added the following to my .vimrc file but when I type ctl + o nothing happnens. When I type ctl + x i get -- ^X mode (^]^D^E^F^I^K^L^N^O^Ps^U^V^Y) at the bottom of vim. 
filetype plugin on
autocmd FileType php set omnifunc=phpcomplete#CompletePHP

A:

What you probably want is Ctrl + xCtrl + o in succession.
Incidentally, I map this to Ctrl + Space so as not to feel like I'm using Emacs.
