Aligning PHP arrays with Emacs

PHP doesn’t require arrays to be aligned in a specific way, but certain coding standards will raise a warning if they’re aren’t aligned correctly. Doing this by hand can be a pain.

emacs-php-align is a small extension that can automatically align arrays. It’s not available on Melpa, but it’s fairly quick to setup.

Once it’s installed, calling M-x align-current will align an array and turn this:

$my_array = array(
    'key' => 'Value',
    'key_two' => 'Another value',
    'really_long_key' => 'Value',
    'k' => 'Value',
);

into this:

$my_array = array(
    'key'             => 'Value',
    'key_two'         => 'Another value',
    'really_long_key' => 'Value',
    'k'               => 'Value',
);
