How can PHP be used to dynamically generate image paths without using domain names?

When dynamically generating image paths in PHP, it is common to use domain names to construct the full URL. However, if you want to generate image paths without relying on domain names, you can use the $_SERVER['HTTP_HOST'] variable to get the current domain and construct the image path relative to that. 

<?php
// Get the current domain
$domain = $_SERVER['HTTP_HOST'];

// Define the image directory path relative to the domain
$imagePath = '/images/';

// Concatenate the domain and image path to generate the full image URL
$imageUrl = 'http://' . $domain . $imagePath . 'example.jpg';

echo $imageUrl;
?>
