PHP layer

This layer adds PHP language support to Spacemacs.
Edit PHP files using php-mode
Edit Drupal files
Run tests with PHPUnit
Reformat code with PHP CBF
The gtags layer is recommended to benefit from better eldoc and
helm-gtags.
To use this configuration layer, add it to your ~/.spacemacs. You will need to
add php to the existing dotspacemacs-configuration-layers list in this
file.
