I was looking up the php function array_merge on php.net and came across this example. Somebody's a Clerks fan. :)

Example 3. array_merge() example

$array_one = array(0 => "jay", 1 => "bob", 2 => "randal", 3 => "dante");
$array_two = array("jay" => "bob", "randal" => "dante", "jay" => "jason");

unset($array_one[2]);

$result_one = array_merge($array_one);
$result_two = array_merge($array_two);

print_r($result_one);
print_r($result_two);
?>

The above example will output:

Array
(
[0] => jay
[1] => bob
[2] => dante
)
Array
(
[jay] => jason
[randal] => dante
)
