What is the significance of setting cookies in the client-side versus the server-side in PHP?

Setting cookies on the client-side allows for more control and flexibility in managing user data, as the cookies are stored on the user's browser. This can lead to faster load times and reduced server load. However, setting cookies on the server-side provides better security and control over the data being stored, as the server has more control over the cookie's expiration and access.

// Client-side cookie setting
setcookie('user_id', '12345', time() + 3600, '/');

// Server-side cookie setting
setcookie('user_id', '12345', time() + 3600, '/', 'example.com', true, true);
