Potřebuji vypsat 3 výsledky, ale aby nemohl být ani jeden stejný jako jiný:

<?php
$RandomList = array();
$RandomList[] = "Discount: 20%";
$RandomList[] = "Discount: 25%";
$RandomList[] = "Discount: 30%";
$RandomList[] = "Discount: 35%";
$RandomList[] = "Discount: 40%";
$RandomList[] = "Discount: 45%";
// Leave next line as is.
echo $RandomList[rand(0,count($RandomList)-1)];
echo $RandomList[rand(0,count($RandomList)-1)];
echo $RandomList[rand(0,count($RandomList)-1)];
?>
