;;; Commentary:
;; PHP Mode is a major mode for editing PHP script. It's an extension;; of CC mode; thus it inherits all C mode's navigation functionality.;; But it colors according to the PHP syntax and indents according to the;; PSR-2 coding guidelines. It also includes a couple handy IDE-type;; features such as documentation search and a source and class browser.
;; Please read the manual for setting items compatible with CC Mode.;; https://www.gnu.org/software/emacs/manual/html_mono/ccmode.html
;; This mode is designed for PHP scripts consisting of a single <?php block.;; We recommend the introduction of Web Mode for HTML and Blade templates combined with PHP.;; http://web-mode.org/
;; Modern PHP Mode can be set on a project basis by .dir-locals.el.;; Please read php-project.el for details of directory local variables.
;; If you are using a package manager, you do not need (require 'php-mode) in;; your ~/.emacs.d/init.el. Read the README for installation instructions.;; https://github.com/emacs-php/php-mode
