You can also put your results into a separate array - then just use the rand fucntion..
here is some code ---
$sayings = array("saying one", "saying two", "saying three");
srand(time());
$i = rand(0,count($sayings));
echo $sayings[$i];
I wish they made this box a bit wider --
I could do some more test. I hope this helps ya. I am ok at coding..
