How can PHP be used to retrieve and process form data, like gender and birthdate selections, from a website's registration form?

To retrieve and process form data like gender and birthdate selections from a website's registration form using PHP, you can use the $_POST superglobal array to access the values submitted through the form. You can then store these values in variables and perform any necessary processing or validation before storing them in a database or displaying them on the website. 

// Retrieve form data
$gender = $_POST['gender'];
$birthdate = $_POST['birthdate'];

// Process the data (e.g., validate, sanitize)
// For example, you can check if the gender and birthdate values are valid

// Store the data in a database or display it on the website
// For example, you can insert the gender and birthdate into a database table
