The "best" (easiest) way to do this would be to use array_rand, this 
can be done as such :
    <?php
        $array = array('a','b','c','d','e','f','g','h','i','j','k','l');
        srand ((double) microtime() * 1000000); 
        $key = array_rand($array,3); 
        $array[$key[0]]; 
        $array[$key[1]]; 
        $array[$key[2]]; 
    ?>
