What are the potential risks of manually sending cookies in PHP?

Manually sending cookies in PHP can pose security risks such as exposing sensitive information or allowing for cookie tampering. To mitigate these risks, it is recommended to use PHP's built-in setcookie() function, which handles the creation and sending of cookies securely. 

// Set a cookie using the setcookie() function
setcookie("cookie_name", "cookie_value", time() + 3600, "/", "example.com", true, true);
