$_POST['groups'] is an array. It's size is going to be dependant on how
many check boxes were checked.
So, in your example, if only blah2 is selected, you'll have
$_POST['groups'][0] == '2'
You can use count($_POST['groups']) to see how many boxes were checked.

This is just wrong.

This assigns the global groups array to one element in a local groups
array. So, if you then do the following, you'd see
$groups = $_POST['groups'];
or
if(isset($_POST['groups']) && is_array($_POST['groups']))
$groups = $_POST['groups'];
else
$groups = array();
so that groups is an (empty) array even if no checkboxes were checked
