Singleton
I'm trying to create a singleton class, but when I try the following code, it seems to create two instances instead of one..
class tessy{
function tessy(){
echo "tell it to queen doppelpopolis!";
}
function getInstance(){
static $instance;
if(!isset($instance)){
$instance =& new tessy();
}
return $instance;
}
}
tessy::getInstance();
tessy::getInstance();
