How can PHP developers ensure their scripts are more universally applicable, considering differences in server configurations and variables like $_SERVER["HTTP_HOST"]?

PHP developers can ensure their scripts are more universally applicable by using server-agnostic functions and variables instead of relying on specific server configurations like $_SERVER["HTTP_HOST"]. One way to achieve this is by using PHP's built-in functions like $_SERVER["SERVER_NAME"] or $_SERVER["REQUEST_URI"] which are more consistent across different server environments. 

$serverName = $_SERVER["SERVER_NAME"];
$requestUri = $_SERVER["REQUEST_URI"];

// Use $serverName and $requestUri in your script instead of $_SERVER["HTTP_HOST"]
