Answer 1

'submitbutton' is the name of your submit button. you can get the names of super global $_POST array elements with array_keys() function

$postnames = array_keys($_POST);

Answer 2

You will find the name in the $_POST array.

<?php
print_r($_POST);
?>

This way you will see everything in the $_POST array.

You can iterate through the array with:

foreach($_POST as $name => $content) { // Most people refer to $key => $value
   echo "The HTML name: $name <br>";
   echo "The content of it: $content <br>";
}

Its like any other POST variable, the name will be in the $_POST array. The name is the key in the $_POST array.
