More details in Debugging Vim Scripts.

Answer 2

Here is a web tutorial on how to use vim as a PHP debugging environment.

Answer 3

See the link on using xdebug with vim that someone else posted for a full debugger, but as an extra tip you can do this from vim to run syntax check on the current PHP script:

:!php -l %

I have this assigned to my F5 key by putting this in my .vimrc file (in your home(~) directory):

nmap <F5> :! php5 -l %<CR>
