Random Images X 4 [solved]

Wanderer

I'm writing a PHP script that displays 4 random images (with links) and displays them in a 2 x 2 table like this.

Anyone have any sample scripts?

The main problem stumping me is that the random pics need to be selected randomly at the same time to avoid duplicates.

Cant you just select them at different times but make sure they havent been selected before? Run through a loop to select them and when one has been chosen add it to an array then check the selected image isnt in the array in future?

OK, that sounds like a plan, any examples?

$image = array();
for ($i = 1; $i <= 4; $i++) {
$newimage = SELECT RANDOM IMAGE;
while (in_array($newimage,$image)) {
$newimage = SELECT ANOTHER RANDOM IMAGE - IT's ALREADY BEEN USED
}
$image[$i] = $newimage
}

That's quickly thrown together in the middle of a busy workday and untested but you should get the jist..?

Thanks Minisweeper, your sample was a little cryptic considering my novice level with PHP but I am a tenacious bugger, I solved the problem.
