Here's the simplest way I've found to get random something without the need for an external file. Simple, but effective.

<?php
 function func(){
  //Randomize selection. In this case, 5 (0,1,2,3,4,5).
  $x = rand()&4; 
  $vars = array(
   //Insert your data into array.
   0 => "var1",
   1 => "var2",
   2 => "var3",
   3 => "var4",
   4 => "var5"
  );
  echo $vars[$x];
 }
?>

The only problem with that is that it's not really random, and that you sometimes get the same result several times. I've seen sollutions to this using microtime(), but I can't think of them off the top of my head.
