How does the method attribute in the HTML form tag affect how PHP receives the form data?

The method attribute in the HTML form tag specifies the HTTP method used to send form data to the server. The two most common methods are GET and POST. When using PHP to process form data, the method attribute determines how the form data is received by the server-side script. If the method is set to GET, the form data is sent in the URL and can be accessed using the $_GET superglobal array in PHP. If the method is set to POST, the form data is sent in the request body and can be accessed using the $_POST superglobal array in PHP. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Access form data sent using POST method
    $username = $_POST['username'];
    $password = $_POST['password'];

    // Process the form data as needed
}
?>
