  • Sorry but it can be better! Nice script, made some tweaks.
    It now gets every photo out of the folder.. and shows them

    <?php
    # Credits: Rickdegraaff.nl

    // extensions to be checked

    $extensions = array('jpg','jpeg');

    // images folder

    $images_folder_path = 'images/projects/';

    // url to folder

    $url_to_folder = 'http://'.$_SERVER['SERVER_NAME'].'/porto/images/projects/';

    // Images Array (SRC value)

    $images = array();

    srand((float) microtime() * 10000000); // IF PHP Version < 4.2.0

    // Open directory and read images

    if ($handle = opendir($images_folder_path)) {
    while (false !== ($file = readdir($handle))) {
    if ($file != "." && $file != "..") {

    // get file extension
    $ext = strtolower(substr(strrchr($file, "."), 1));

    if(in_array($ext, $extensions))
    {
    $images[] = $url_to_folder.$file;
    }

    }
    }
    closedir($handle);
    }
    foreach ($images as $imgvalue) {
    print '
    ';
    }
    ?>

  • Good basic script.

    You can: Make your rand_key array equal to the number of images that you want to show, then create a loop to display each image. This simple change makes this much more versatile.

    Cheers

  • A lot less code? Could be, but think how many beginners would actually understand a similar script with less code. The current application is well commented and gives the user an idea of how this script is actually working (step by step).
