Equal spacing / lining up of variables

Is there a way natively or with a package add-on to evenly space variable definitions within PHP  to make them pretty?

e.g.

$this_is_a_variable = $my_value_array['something'];

$a_variable = $my_value_array['something-else'];

$another_variable = $my_value_array['something-more'];

and make it look like

$this_is_a_variable = $my_value_array['something'];

$a_variable            = $my_value_array['something-else'];

$another_variable   = $my_value_array['something-more'];
