Say I have an array $order
containing the data of entire order and user as well.
To display the name of user; I use $order['users'][33]['firstname'];
. I do this in several parts of page.
Does it really matter to the memory and process to do this way (using associative array)? Or should I store user in a variable
$user = $order['users'][33]['firstname'];
and keep using $user where ever needed? Which method is prefered?
