What are the benefits of defining links as objects in PHP classes instead of using global variables for URL values?

Defining links as objects in PHP classes instead of using global variables for URL values helps in encapsulating the link data within the class, making it more organized and easier to manage. It also promotes code reusability and allows for better control over the link properties. Additionally, using objects allows for easier modification and maintenance of links throughout the codebase. 

class Link {
    private $url;

    public function __construct($url) {
        $this->url = $url;
    }

    public function getUrl() {
        return $this->url;
    }

    public function setUrl($url) {
        $this->url = $url;
    }
}

$link = new Link('https://www.example.com');
echo $link->getUrl(); // Output: https://www.example.com

$link->setUrl('https://www.newexample.com');
echo $link->getUrl(); // Output: https://www.newexample.com
