How does PHP handle data types when extracting values from cookies?

PHP automatically converts the values extracted from cookies to the appropriate data types based on their content. However, to ensure that the data types are preserved as intended, you can explicitly cast the extracted values to the desired data type. 

// Extracting a cookie value and casting it to integer
$userId = (int)$_COOKIE['user_id'];

// Extracting a cookie value and casting it to float
$price = (float)$_COOKIE['product_price'];

// Extracting a cookie value and casting it to string
$username = (string)$_COOKIE['username'];
