How to get random value out of an array?

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.

php arrays random

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)];

php arrays random

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;}
