Declaring an array

Question

$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?

Answer 1

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

Answer 2

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.

Answer 3

Yes, It automatically increasing a index but start with '0'.

Answer 4

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();

Answer 5

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