This is the snippets file for Laravel 4. You can use
:set ft=php.laravel
to enable it in current buffer, or just add the following line to .vimrc
autocmd FileType php set ft=php.laravel
to enable it for every php files.
Or, You also can set the filetype based on directory, like
autocmd BufNewFile,BufRead ~/proj/src/php/laravel/*.php setlocal filetype=php.laravel
BTW, you will need SnipMate or UltiSnips for using this snippets.
Most important is, this snippets based on laravel 4 for sublime text from @bliker
