forms - PHP: Possible to automatically get all POSTed data?

Question

Simple question: Is it possible to get all the data POSTed to a page, even if you don't know all the fields?

For example, I want to write a simple script that collects any POSTed data and emails it. I can foresee that the fields in the form are likely to change a lot over time, and so to save myself some time in the long run, I was wondering if I could write something that automatically gathered everything?

Is it possible?

Sure. Just walk through the $_POST array:

foreach ($_POST as $key => $value) {
    echo "Field ".htmlspecialchars($key)." is ".htmlspecialchars($value)."<br>";
}
