How to get random value out of an array?

You can use mt_rand()

$random = $ran[mt_rand(0, count($ran) - 1)];

This comes in handy as a function as well if you need the value

function random_value($array, $default=null)
{
    $k = mt_rand(0, count($array) - 1);
    return isset($array[$k])? $array[$k]: $default;
}

PHP provides a function just for that: array_rand()
http://php.net/manual/en/function.array-rand.php

$ran = array(1,2,3,4);
$randomElement = $ran[array_rand($ran, 1)];

You can also do just:

$k = array_rand($array);
$v = $array[$k];

This is the way to do it when you have an associative array.

$value = $array[array_rand($array)];
