How can the PHP $_POST superglobal be properly utilized to retrieve form data?

To properly utilize the PHP $_POST superglobal to retrieve form data, you need to ensure that the form method is set to "post" and that the input fields in the form have a "name" attribute. Then, in the PHP script that processes the form data, you can access the submitted values using $_POST['input_name']. 

<form method="post">
    <input type="text" name="username">
    <input type="password" name="password">
    <input type="submit" value="Submit">
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Process the form data
}
?>
