Posted 2021-02-26

This snippet will create an array of all images in a directory and sub-directories and display them randomly.

<?php
//path to directory to scan. i have included a wildcard for a subdirectory
$directory = "images/*/";
 
//get all image files with a .jpg extension.
$images = glob("" . $directory . "*.jpg");
 
$imgs = '';
// create array
foreach($images as $image){ $imgs[] = "$image"; }
 
//shuffle array
shuffle($imgs);
 
//select first 20 images in randomized array
$imgs = array_slice($imgs, 0, 20);
 
//display images
foreach ($imgs as $img) {
    echo "<img src='$img' /> ";
}
?>
