check the manual on the rand(); function ..
If you want to make sure this number is unique .. create an array storing
all the numbers you've used once and do some nice tricks with a loop and
stuff untill you get a nice unique random number ... like this:
?php
$UsedValues = Array();
function GetRandomNumber() {
while( $Rand = round( rand(0, 1000) ) ) {
# Using round() to round the float returned by rand()
if (!in_array($Rand, $UsedValues)) return $Rand;
array_push($UsedValues, $Rand);
}
};
?
