How can one efficiently store and retrieve image paths for random display without using a database in PHP?

Storing and retrieving image paths for random display without using a database in PHP can be achieved by storing the paths in an array and then randomly selecting one for display. This can be done by using the `glob()` function to retrieve all image paths in a directory, storing them in an array, and then using `array_rand()` to randomly select one of the paths for display. 

<?php
// Directory where images are stored
$directory = 'images/';

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

// Randomly select an image path
$randomImagePath = $images[array_rand($images)];

// Display the image
echo '<img src="' . $randomImagePath . '" alt="Random Image">';
?>
