If I have an array that is filled with stored $_GET variables how can I know the stored amount?

Would a simple count($_SESSION['cart']) work??

if $_SESSION['cart'] IS an array, then yes,
count($_SESSION['cart'])

will tell you how many items are stored in that array.

FYI: Using a foreach you can then iterate over its contents:
foreach( $_SESSION['cart'] as $i=>$value )
{
 echo $i . " " . $value . "<br />";
}
