I would like to know how if it's possible to validate if a PHP file is valid in VIM without closing VIM every time?

Thank you

You can execute shell commands in vim. This is the same as calling php -l filename.php from the shell: 

:!php -l %

I have this mapped into my ~/.vim/after/ftplugin/php.vim file so that I only have to press F5: 

map <F5> :!php -l %<CR>

Note this will validate the saved file, so if you have unsaved changes, it won't see them. –  Useless Sep 1 '11 at 14:55
    
Can we use a different key for mapping like: CTRL+P? –  Tech4Wilco Sep 21 '11 at 17:37

@Jimmy, I think it would be something like map <C-P> :!php -l %<CR>. –  gpojd Sep 22 '11 at 15:58

Use :make with the following php specific settings:

:set makeprg=php\ -l\ %
:set errorformat=%m\ in\ %f\ on\ line\ %l,%-GErrors\ parsing\ %f,%-G

Your syntax errors will be in the Quickfix window. You can open this buffer with :copen or :cope for short. If you only want to open the window only if their are errors use :cwindow.

You can use :cnext and :cprev to move through the quickfix list to jump to the corresponding errors. I suggest Tim Pope's excellent unimpared.vim plugin to make moving through the list as simple as [q and ]q.

To simplify the workflow I suggest a mapping like this one:

nnoremap <f5> :update<bar>make<bar>cwindow<cr>

Now you can just hit <f5> and the buffer will be updated (if necessary), linted, and any errors will appear in the quickfix window.

To make this a bit more robust, add these commands to ~/.vim/after/ftplugin/php.vim. Example ~/.vim/after/ftplugin/php.vim

setlocal makeprg=php\ -l\ %
setlocal errorformat=%m\ in\ %f\ on\ line\ %l,%-GErrors\ parsing\ %f,%-G
nnoremap <buffer> <silent> <f5> :update<bar>sil! make<bar>cwindow<cr>

For more information:

:h quickfix
:h makeprg
:h errorformat

When I run this code, it works but makes the buffer completely blank. –  Allain Lalonde May 17 '12 at 15:44
    
The mapping provided will only write the buffer *if needed), lint via the makeprg, and then show the quickfix window if there are errors. It does not make any changes to the buffer in any way other than possibly writing it to disk. Is there a chance you are looking at a blank quickfix window? –  Peter Rincker May 17 '12 at 16:04

Try http://www.vim.org/scripts/script.php?script_id=2736 it's very good.

seems complicated to me –  Tech4Wilco Sep 1 '11 at 15:11
    
Worked flawlessly for me. –  Allain Lalonde May 17 '12 at 15:48

To check PHP syntax without having to save first you can use:

map :w !php -l

There is another plugin called vim-phpqa that marks the line:
