You want array_rand()

or you could shuffle() and always just reference $array[0] which would also be "random"

You need array_rand function for that . the Parameters are array_rand ( array $input [, int $num_req = 1 ] ) . For your purpose , use it as $var_rand = array_rand($arr); as you want only 1 random number generated . For more help, refer to this

Also , for future questions , post your php version too. Some functions are not available in older versions . This one is available , though.

You can do that as following,

<?PHP

$numbers = array(1 => 1, 2 => 2, 3 => 3, 4 => 4, 5 => 5, 6 => 6);
$random_key = array_rand($numbers, 1);
print $random_key;

?>
