What is the correct syntax for checking a cookie value in PHP?

To check a cookie value in PHP, you need to use the isset() function to determine if the cookie is set, and then access the cookie value using the $_COOKIE superglobal array. This allows you to retrieve and verify the value stored in the cookie. 

if(isset($_COOKIE['cookie_name'])) {
    $cookie_value = $_COOKIE['cookie_name'];
    // Check the value of the cookie here
    echo "Cookie value: " . $cookie_value;
} else {
    echo "Cookie not set";
}
