Ouputting $_POST element name instead of value

[ekung]

How can I output the element name (instead of the value) of a $_POST array?

I am trying to foreach-loop through the array to get the HTML form's text box names but I have no idea how to do this, however much I research.

Thanks in advance.

The snippet below is what I have so far but I know it only outputs the value of the element, rather than the name, which is what I need as the parameter for my function "makeButtons()". Also, I would want to use the element name of "submit" instead of the value "Create Buttons" below:

foreach ($_POST as $user_attribute){
	if ($user_attribute!="Create Buttons"){
		makeButtons($user_attribute);
}
}

as usual, there's more than one way to skin a cat.

reset($_POST);
foreach ( $_POST as $key => $value ){
    print "$key => $value<br>\n";
}//end foreach
