Image only seen once

    Hello,

    I am trying to come up with a way so a series of random images will only appear once using sessions. I've been struggling with this for awhile and I just can't figure out how to do this.

    so maybe like when an Image first showed up I would have $_SESSION[$random_image] = 1; //1 representing that it has been viewed

    However I don't know where to go from there, any ideas?

    Thank You!

    if(empty($_SESSION['in_progress']))
{
   $_SESSION['in_progress'] = 1;
   $_SESSION['images'] = generate_images();
}

if(count($_SESSION['images']) > 0)
{
   work_with(array_pop($_SESSION['images']));
}
    Code (markup):

    joebert your script is almost right
    You can try this

    
$list = array();//Your list of files

foreach($_SESSION['shown'] as $v){
unset($list[$v]);
}

//Then select a random file
$toshow = current($list);
$_SESSION['shown'][$toshow] = $toshow; //Mark as shown
