Goal

vim-php-namespace is a helper script for inserting "use" statements automatically.

Installation:

If you don't use tpope/pathogen:

Copy plugin/phpns.vim to ~/.vim/plugin/

Add your custom mapping:

Add this in ~/.vim/ftplugin/php.vim:

imap <buffer> <F5> <C-O>:call PhpInsertUse()<CR>
map <buffer> <F5> :call PhpInsertUse()<CR>

The script makes use of tag files. If you don't already use a tag file you may create one with the following command; after having installed ctags-exuberant:

ctags-exuberant -R --PHP-kinds=+cf

Usage:

When the cursor is on a classname, hit F5 to add the corresponding use statement.
