What is the purpose of checking if a user's browser allows cookies in PHP?

Checking if a user's browser allows cookies in PHP is important because cookies are commonly used to store user-specific information or session data. If a user's browser does not allow cookies, certain functionalities of a website may not work as expected. To address this issue, you can check if cookies are enabled in the user's browser using PHP and provide appropriate messaging or alternative solutions if cookies are disabled. 

if(isset($_COOKIE['test_cookie'])) {
    echo "Cookies are enabled.";
} else {
    echo "Cookies are disabled. Please enable cookies in your browser for the best experience.";
}
