What is the best practice for configuring social media links in PHP?

When configuring social media links in PHP, it is best practice to store the URLs in a separate configuration file or database table. This allows for easy management and updating of the links without having to modify the actual PHP code. Using constants or variables to store the URLs can also make it easier to access and use them throughout your application.

// Config file
define('FACEBOOK_URL', 'https://www.facebook.com/example');
define('TWITTER_URL', 'https://www.twitter.com/example');
define('INSTAGRAM_URL', 'https://www.instagram.com/example');

// Usage in PHP code
echo '<a href="' . FACEBOOK_URL . '">Facebook</a>';
echo '<a href="' . TWITTER_URL . '">Twitter</a>';
echo '<a href="' . INSTAGRAM_URL . '">Instagram</a>';
