Good tip! There is also the array_rand way. However, as I was trying it just now, it seems to love its zeros, so I decided to do a little test as well. This is the array_rand code:

php Code:

$aFilms = array("V For Vendetta", "Requiem For A Dream", "Jacob's Ladder");
echo $aFilms[array_rand($aFilms)];

And this is my test code as it appeared to be quite fond of returning zero:

php Code:

$aCount = array(0, 0, 0);
$aFilms = array("V For Vendetta", "Requiem For A Dream", "Jacob's Ladder");

for($iIndex = 0; $iIndex <= 5000; $iIndex++)
{
    $aCount[array_rand($aFilms)]++;
}

print_r($aCount);

Results were quite surprising as I thought zero would have been much more dominant:

[0] => 1701
[1] => 1637
[2] => 1663
