How can the PHP code be modified to correctly retrieve and display the form input data?

The issue is that the PHP code is not correctly accessing the form input data. To solve this, we need to use the `$_POST` superglobal array to retrieve the form input data. We can then use the `echo` function to display the data on the page. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    echo "Name: " . $name . "<br>";
    echo "Email: " . $email;
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    Name: <input type="text" name="name"><br>
    Email: <input type="email" name="email"><br>
    <input type="submit" value="Submit">
</form>
