How to align list items in vim [duplicate]

Question

Say I have PHP code which looks like this

$values = array(
    'foo' => 'bar',
    'longfoo' => 'otherbar',
    'baz' => 'foobar,
);

Is there a way in Vim to align the array values and format it like following?

$values = array(
    'foo'       => 'bar',
    'longfoo'   => 'otherbar',
    'baz'       => 'foobar,
);

Minor note: I use spaces, not tabs for indenting.

Answer 1

The tabular plugin would make that easy. After installing that you could simply run

:Tabularize /=>/

while on any of the lines which are to be aligned. If you use that same pattern often, you could even setup a mapping to do that even faster.
