如何从文件夹中获取图像？

Question

I have a folder named as images. I just want to fetch those images from the folder and show them randomly on web page. When the user refreshes the page, the image should change. Thank you.

Answer 1

An idea could be:

1. you fetch all the images names frome the images folder
2. you randomly pick one
3. you visualize that one

so you can go like this

<?
    $dir = '/my_directory_location'; 
    $files = scandir($dir);  
    $rand_img = array_rand($files, 2);
    $imcolumn = "<img src=$rand_img alt=$rand_img><br>";
?>

<?= $imcolumn ?>
