(Hello, Planet Ubuntu Users!  I’m looking for a second MOTU on my php-xdebug package as well as someone to revu my libapache-test-perl package.  Any takers?) Emacs CVS now includes XFT (i.e. smooth fonts) in the main branch, so I’m discontinuing my old emacs-xft-snapshot build.  Still, the other emacs-snapshot package is targeted to Debian and I’m running Ubuntu Gutsy.  So I’ve uploaded a snapshot build to my PPA on Launchpad. One thing that I included is flymake support for PHP.  Carl asked me earlier today if I knew how to get the compilation mode in Emacs to work with PHP’s lint function to find highlight problems.  I said flymake would be better, but didn’t know how to do that right off, either. After a bit of twiddling, I figured it out and, as a bonus, got compilation mode figured out, too. If you want to enable flymake for PHP-mode (yes, I have a Debian package for that, too) in a version of Emacs you already have installed, add the following code to your .emacs file:

;; Flymake PHP Extension (require 'flymake) (unless (fboundp 'flymake-php-init)   (defun flymake-php-init ()     (let* ((temp-file (flymake-init-create-temp-buffer-copy                        'flymake-create-temp-inplace))            (local-file (file-relative-name                         temp-file                         (file-name-directory buffer-file-name))))       (list "php" (list "-f" local-file "-l"))))) (let ((php-ext-re "\\.php[345]?\\'")       (php-error-re        "\\(?:Parse\\|Fatal\\) error: \\(.*\\) in \\(.*\\) on line \\([0-9]+\\)"))   (unless (assoc php-ext-re flymake-allowed-file-name-masks)     (add-to-list 'flymake-allowed-file-name-masks                  (list php-ext-re                    'flymake-php-init                    'flymake-simple-cleanup                    'flymake-get-real-file-name))     (add-to-list 'compilation-error-regexp-alist-alist                  (list 'compilation-php                    php-error-re  2 3 nil nil))     (add-to-list 'compilation-error-regexp-alist 'compilation-php)     (add-to-list 'flymake-err-line-patterns                  (list php-error-re 2 3 nil 1))))

Now, whether you’re using the emacs you started with or the latest emacs-snapshot, you need to tell emacs to use flymake on PHP files.  Add:

(add-hook 'php-mode-hook (lambda () (flymake-mode t)))

to your .emacs file and you’re good to go.
