What is the best way to debug the existence of cookies in PHP?

To debug the existence of cookies in PHP, you can use the isset() function to check if a specific cookie is set. If the cookie is set, you can then use the $_COOKIE superglobal to access its value. This can help you determine if the cookie exists and contains the expected data. 

// Check if a specific cookie is set
if(isset($_COOKIE['cookie_name'])) {
    // Access the cookie value
    $cookie_value = $_COOKIE['cookie_name'];
    echo "Cookie 'cookie_name' exists with value: " . $cookie_value;
} else {
    echo "Cookie 'cookie_name' does not exist";
}
