Just to give you something to chew on, try the code below.
<?php
$myResultsArray = array();
$numberOfRandNumbersToGet = 3;
$randomNumberRange = 20;
while(count($myResultsArray) < $numberOfRandNumbersToGet)
{
do {
$rand = rand(1, $randomNumberRange);
}while(in_array($rand, $myResultsArray));
$myResultsArray[] = $rand;
}
print_r($myResultsArray);
// If you really want $one, $two, $three for exactly three results:
list($one, $two, $three) = $myResultsArray;
echo "1: $one\n2: $two\n3: $three\n";
?>
It is slightly more generic, and you can change things a little
without having to modify a whole bunch of if() statements.

Subject: [PHP] Randomizing 3 different numbers.
I am tring to output 3 different random numbers between 1
and 20 into 3 different strings. Using Rand() for each
string isn't sufficient as I may get the same number
repeated for one of the other strings- eg 1,1,3 or 5,3,3 .
It's important that I get three different numbers outputted
into for example $one, $two, $three.
Can anyone help?
Ian
