foreach() vs HTTP_POST_VARS

[cs2314]

I'm getting the "Warning: Invalid argument supplied for foreach() in" error. I realize that it means that the variable I'm using in my foreach line is not of an array type. However I thought HTTP_POST_VARS was an array. Can anyone see what I'm doing wrong?

class paypal_ipn
{
var $paypal_post_vars = $HTTP_POST_VARS;

function send_response()
{
.....

foreach($this->paypal_post_vars as $key => $value) {
     if (@get_magic_quotes_gpc()) {
	$value = stripslashes($value);
	}
	$values[] = "$key" . "=" . urlencode($value);
}
          .....

for a start $HTTP_POST_VARS are depreciated and ar not a super global, you should be using $_POST, if your following anything that uses $HTTP_POST_VARS, its well out of date.
