What is the best way to list all the parameters passed through a form on a new page in PHP?

When submitting a form in PHP, all the parameters passed through the form can be accessed using the $_POST or $_GET superglobal arrays. To list all the parameters on a new page, you can loop through these arrays and display the key-value pairs. 

<?php
foreach ($_POST as $key => $value) {
    echo $key . ': ' . $value . '<br>';
}

foreach ($_GET as $key => $value) {
    echo $key . ': ' . $value . '<br>';
}
?>
