How can PHP be used to retrieve and process form data submitted via POST method?

To retrieve and process form data submitted via the POST method in PHP, you can use the $_POST superglobal array. This array contains key-value pairs of all the form data submitted via POST. You can access the form data by using the name attribute of the form fields as keys in the $_POST array. 

// Retrieve form data submitted via POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];

    // Process the form data
    // For example, you can validate the input, perform database operations, etc.
}
