General Qstn;

Is it best practice when dealing wit lots of session variables. to.

Insert them in array as such, because i cant see what advantage it would b.

$_SESSION['serv'] = array();
$_SESSION['date'] = $_POST['date'];
$_SESSION['service'] = $_POST['service'];

What you've shown there is exactly what I do. Whether it's "best practice" or not is open to opinion, I guess.

Well, in your example you haven't actually done anything different, you declared $_SESSION['serv'] as an array, but you never use it after. Maybe you meant:

$_SESSION['serv'] = array();
$_SESSION['serv']['date'] = $_POST['date'];
$_SESSION['serv']['service'] = $_POST['service'];

if so, I can see advantages of this, quick examples that pop into my head are when dealing with shopping carts.

If you meant as per Brandoe85's example then the advantage is that your are giving your variables a `namespace` of sorts , its really easy to end up with lots of session variables with names that may confuse ..


Is that the number of items in a cart or the number of login attempts or ..?
OK you can use $_SESSION['cart_num'] etc but personally I prefer the array access.

Variable naming conventions can save you hours of headaches for little effort, & I wish I had realised that the first time I was told so !
