Question: What is the best way of doing this ?

```
rand('Helloworld','Hi world');

```

I know this is not working as rand needs a min and max number, but what is the solution for this ?

Answer: 
Use [array\_rand](http://php.net/manual/en/function.array-rand.php).
Something likes that:

```
<?php
$array = array(1, 2, 3);
$array[ mt_rand( 0, count($array) -1 ) ];
?>

```
