What is the best way to display multiple images from a folder using PHP without the need for a MySQL database?

When displaying multiple images from a folder using PHP without the need for a MySQL database, you can use PHP's directory functions to scan the folder for images and then display them on the webpage using HTML image tags.

<?php
// Path to the folder containing images
$folder = "path/to/images/";

// Get all files in the folder
$files = scandir($folder);

// Loop through the files and display images
foreach($files as $file){
    if(in_array(pathinfo($file, PATHINFO_EXTENSION), array('jpg', 'jpeg', 'png', 'gif'))){
        echo '<img src="' . $folder . $file . '" alt="' . $file . '" />';
    }
}
?>
