What keys are generated when pushing an array element with empty square bracket syntax $array[]?

$a[]="Anna";
$a[]="Brittany";
$a[]="Cinderella";
$a[]="Diana";
$a[]="Eva";
$a[]="Fiona";
$a[]="Gunda";

When declaring it this way, does it automatically increase the index? Why is this ideal?

Yes its ideal, because if its not, then use an associative array.

Yes, it does. See the PHP arrays guide. Note that if you want to delete the array, you can use:

unset($a);

Or if you want to make $a become an empty array, you can use:

$a = array();

Yes, it does. It may not be 'ideal' - but considering that you're setting an array equal to a single value, adding to the array is better than overwriting the entire array, which I suppose would be the other option for that statement.

Yes it does. It may not be ideal for you, but it sure is convenient for most people.
