In what scenarios would it be necessary or beneficial to use multiple cookies in PHP, and how can they be managed effectively to avoid conflicts?

When dealing with multiple cookies in PHP, it may be necessary or beneficial to use them to store different types of information or settings for a user. To manage multiple cookies effectively and avoid conflicts, it is important to give each cookie a unique name and path to ensure they do not overwrite each other. Additionally, setting an appropriate expiration time for each cookie can help prevent conflicts. 

// Set multiple cookies with unique names and paths
setcookie('cookie1', 'value1', time() + 3600, '/');
setcookie('cookie2', 'value2', time() + 3600, '/admin');
setcookie('cookie3', 'value3', time() + 3600, '/settings');
