String of 5 unique random letters

[miraan]

Hi,
Right now I am working on creating a string of 5 random letters. I have already created the script, it does create a unique random letter but it repeats it 5 times. Here is what I have so far:

<?php
srand();
$random=chr(rand(ord("A"),ord("Z")));
$string="";
for ($i=1;$i<6;$i++) {
	$string .= $random;
}
echo $string;
?>

It diplays 5 of the same letters, I want unique letters.

By calling it as a function produces a unique letter:

srand();
function randletter()
{
	return  chr(rand(ord("A"),ord("Z")));
}
$string="";
for ($i=1;$i<6;$i++) {
	$string .= randletter();
}
echo $string;
