Code: Select all: <?php class cars { public $cars = array("Saab","Volvo","BMW","Toyota"); public function array_cars(){ return $this->cars; } } $cars = new cars; $cars_array = $cars->array_cars(); for($i=0; $i<4;$i++) echo $cars_array[$i]; ?>

See if you can wrap your head around that. ;)

Old thread, but I'm bored so:

isset — Determine if a variable is set and is not NULL

http://www.php.net/manual/en/function.isset.php

All it is doing is making sure that $msg is not empty, and if it's not empty that print $msg.
