What is the best approach to navigate through files (images) in PHP?

When navigating through files (images) in PHP, the best approach is to use the `glob()` function to retrieve an array of file paths that match a specified pattern. This allows you to easily loop through the array and perform actions on each file. 

// Specify the directory where the images are located
$directory = 'path/to/images/';

// Get an array of file paths for all images in the directory
$images = glob($directory . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

// Loop through the array of file paths and perform actions on each image
foreach ($images as $image) {
    // Do something with each image, such as displaying it or processing it
    echo '<img src="' . $image . '" alt="Image">';
}
