How can PHP be used to extract and process data submitted through HTML forms?

To extract and process data submitted through HTML forms using PHP, you can use the $_POST superglobal array to access the form data that was sent via the POST method. You can then use this data to perform any necessary processing or validation before storing it in a database or displaying it on a webpage. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Process the form data as needed
    // For example, you can insert it into a database or send it in an email
    
    echo "Thank you for submitting the form, $name!";
}
?>
