help with a random number generator.

slapdashwebdesign · February 1, 2008

I have created a script to attempt to make random images appear.

to see it in action go to http://slapdash.grimhq.com/imagerotater/imagerotator.php.

the problem i am having is the repeating of images.

i have tried to create it so it would not repeat but it does not work. there must be a better way.

here is my script.

help please.

<?php
//create a random value for each circle
$cir1 = rand(1,5);
$cir2 = rand(1,5);
$cir3 = rand(1,5);
$cir4 = rand(1,5);
$cir5 = rand(1,5);
//we now need to check to make sure it is not equal to any other value so we do not have repetitive circles
//cir1
while ($cir1 == $cir2) {
$cir2 = rand(1,5);
}
while ($cir1 == $cir3) {
$cir3 = rand(1,5);
}
while ($cir1 == $cir4) {
$cir4 = rand(1,5);
}
while ($cir1 == $cir5) {
$cir5 = rand(1,5);
}
//cir2
while ($cir2 == $cir1) {
$cir1 = rand(1,5);
}
while ($cir2 == $cir3) {
$cir3 = rand(1,5);
}
while ($cir2 == $cir4) {
$cir4 = rand(1,5);
}
while ($cir2 == $cir5) {
$cir5 = rand(1,5);
}
//cir3
while ($cir3 == $cir1) {
$cir1 = rand(1,5);
}
while ($cir3 == $cir2) {
$cir2 = rand(1,5);
}
while ($cir3 == $cir4) {
$cir4 = rand(1,5);
}
while ($cir3 == $cir5) {
$cir5 = rand(1,5);
}
//cir4
while ($cir4 == $cir1) {
$cir1 = rand(1,5);
}
while ($cir4 == $cir2) {
$cir2 = rand(1,5);
}
while ($cir4 == $cir3) {
$cir3 = rand(1,5);
}
while ($cir4 == $cir5) {
$cir5 = rand(1,5);
}
//cir5
while ($cir5 == $cir1) {
$cir1 = rand(1,5);

}
while ($cir5 == $cir3) {
$cir3 = rand(1,5);
}
while ($cir5 == $cir4) {
$cir4 = rand(1,5);
}
//there might be a better way but i just did this quick
//now we must assign the values of 1-4 to the source of an image

It looks random, there are only 5 images anyway and no two images get displayed. What is wrong?
