I ended up using an example from the PHP website.
<?php
$input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");
$rand_keys = array_rand($input, 2);
echo $input[$rand_keys[0]] . "\n";
echo $input[$rand_keys[1]] . "\n";
?>
Just extended the array to the number of lines I needed.
That works, but shuffle() is cleaner and then you can echo things
out with a foreach() expression.

If you're doing a shuffle inside a loop, it's going to be even slower.
Might not be an issue for the OP but after your array gets to a certain
size, doing that will be a problem.
