random select *2

[dagon]

I have the following svript which takes $dirr arras for picking an image. I want it to pick 2 images.

foreach ($dir as $key => $base_dir)
{
$i = 0;
$images = opendir ($DOCUMENT_ROOT.$base_dir);
while ($f = readdir($images))
{ if ($f != '.' && $f != '..')
{$img[$i++] = $f;}
}
closedir ($images);

$output = "/".$base_dir."/".$img[rand(0,sizeof($img)-1)];

unset ($img); //clear $img for next cycle

$h_w = GetImageSize ($DOCUMENT_ROOT.$output);

$$key = "<img border=\"0\" src=\"$output\" $h_w[3]" ;
}

the secound one should $$key2

how do i do that?
I considered just feeding the dir through twice but that would opendir and read it twice which seems inefficient.

Here is some code I wrote to get a list of images in a dir and display the thumbnails. I did this so the owner of the site could simply add / delete images to the image dir and the gallery page would show the chages.

       // Get list of photos
        $image_directory = ROOT_PATH."gallery";
        if ($dir = @opendir($image_directory)) {
        $count = 0;
                while (($imageThumb = readdir($dir)) !== false) {
                        If (eregi("_thumb.jpg$", $imageThumb)) {
                                If (file_exists($imageFull = "glry_".eregi_replace("_thumb", "", $imageThumb))) {
                                        //$thumbArray = getImageSize($image_directory."/".$imageThumb);
                                        If ($fullArray = getImageSize($image_directory."/".$imageFull)) {
                                                $photoList[$count]["thumbImage"] = "/gallery/".$imageThumb;
                                                $photoList[$count]["fullImage"] = "/gallery/".$imageFull;
                                                $photoList[$count]["fullWidth"] = $fullArray[0];
                                                $photoList[$count]["fullHeight"] = $fullArray[1];
                                                $photoList[$count]["windowWidth"] = ($fullArray[0]+50);
                                                $photoList[$count]["windowHeight"] = ($fullArray[1]+100);
                                                $count++;
                                        } //end If($fullArray)
                                } // end If(eregi_replace())
                        } //endIf(eregi())
                } // end While()
         closedir($dir);
        }// endIf

I create an array $photoList[] which has the file names for all the available (all images in the dir) images. There is a bunch more stuff going on in this code as I do more with the results later, but maybe this can help you develop the code you need to loop through the directory and get what you need.
