You can use array_rand to get a random element from an array:

$strings= array('one', 'two', 'yes', 'no', 'yeaa');
$random_str = $strings[array_rand($strings)];

Or you can just use the rand() function.

$strings= array('one', 'two', 'yes', 'no', 'yeaa');
$random_str = $strings[rand(0,4)];

You can use:

<?php

mt_srand(time() * 1000);

$strings= array('one', 'two', 'yes', 'no', 'yeaa');
$ramdom_str = $strings[mt_rand(0, sizeof($strings)-1)];

?>

mt_srand and mt_rand are better implementations of rand and srand
