What are the advantages and disadvantages of using absolute URLs vs relative URLs in PHP, especially in the context of frameworks like Symfony?

When working with frameworks like Symfony in PHP, using absolute URLs can provide more flexibility and prevent issues with routing and linking between pages. However, absolute URLs can be longer and harder to maintain compared to relative URLs. In most cases, using Symfony's built-in functions to generate URLs dynamically based on routes is recommended to ensure consistency and flexibility in your application. 

// Using Symfony's built-in functions to generate absolute URLs
$url = $this->generateUrl('route_name', ['param' => 'value']);
echo $url;
