Doesn't stop/start phpXX service

[jefflenz]

Should add a brew services stop phpXX; brew services start phpYY so we don't have to do this manually every time I switch.

stupid question: what is the php service / when's it needed?

Hello.
@bkdotcom PHP-FPM services. They need to be stopped and started.

@jefflenz Look at PR #36 maybe.
We are many people using php-fpm + nginx so merging this PR is required for phpswitch.sh to be useful at all.
