How can PHP developers handle different server configurations for development and live environments when including files with links and images?

When including files with links and images in PHP, developers can use relative paths to ensure that the links and images are correctly displayed in both development and live environments. By using relative paths, developers can avoid hardcoding specific server configurations and adapt to different environments seamlessly.

<?php
// Define the base URL for links and images
$base_url = "http://example.com/";

// Include a file with a link using a relative path
include "header.php";

// Display an image using a relative path
echo "<img src='" . $base_url . "images/example.jpg' alt='Example Image'>";
?>
