You can use numeric values in the brackets to create a scalar array...
$array[0] = 'first';
$array[1] = 'second';
of you can create associative arrays for key/value pairs, such as ...
$array['age'] = 18;
$array['date'] = '2007-11-05';
Depending on your application, one may be more useful that the other.
