What potential issues can arise when setting multiple cookies in PHP using setcookie()?
Setting multiple cookies in PHP using setcookie() can lead to unexpected behavior if the cookies are not properly separated by using different keys. To avoid conflicts, ensure each cookie has a unique name. This can be achieved by appending a unique identifier to the cookie name for each setcookie() call.
// Set multiple cookies with unique names
setcookie('cookie1', 'value1', time() + 3600);
setcookie('cookie2', 'value2', time() + 3600);
