I have an array called $ran = array(1,2,3,4);
I need to get a random value out of this array and store it in a variable, how can I do this?
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 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)];
