How can one check if a user's browser is properly configured to accept cookies in PHP?

To check if a user's browser is properly configured to accept cookies in PHP, you can use the `setcookie()` function to set a test cookie and then check if it is successfully set by checking if it exists in the `$_COOKIE` superglobal. If the test cookie is not set, it means the user's browser is not configured to accept cookies. 

// Set a test cookie
setcookie('test_cookie', 'test', time() + 3600);

// Check if the test cookie is set
if(isset($_COOKIE['test_cookie'])) {
    echo 'Cookies are enabled.';
} else {
    echo 'Cookies are disabled.';
}
