i am creating a simple authentication, acl script. i wonder if its ok to store a PDO database handle in a global variable?
whats the bad effects of using a global variable? anyone can edit from anywhere?
if i create a singleton like in zend framework Zend_Registry how will it make things any better?
It’s fine. It will be destroyed when the request is over anyway so no other process will edit it or anything. Just make sure you use include_once so it doesn’t connect every time.
