php - Select random file from directory

Question

I'm trying to make a site where users can submit photos, and then randomly view others photos one by one on another page. I have a directory called "uploads" where the pictures are submitted. I'm having trouble reading the pictures from the file. I just want to randomly select a picture from the directory uploads and have it displayed on the page. Any suggestions appreciated.

You can use glob to get all files in a directory, and then take a random element from that array. A function like this would do it for you:

function random_pic($dir = 'uploads')
{
    $files = glob($dir . '/*.*');
    $file = array_rand($files);
    return $files[$file];
}
