How can multiple variables be extracted from HTML forms in PHP?

To extract multiple variables from HTML forms in PHP, you can use the $_POST superglobal array to access form data sent via the POST method. Each form input field should have a unique name attribute, which will then be used as the key to access the corresponding value in the $_POST array. 

// Assuming a form with input fields named 'username' and 'email'
$username = $_POST['username'];
$email = $_POST['email'];

// Now $username and $email variables contain the values submitted from the form
