Help with setting variables

[fartsniff]

hello all,
this is some code that i am using that "loops" through all of the variables
that paypal
ships back to me via ipn.

for ($x=0; $x < count($postvars); $x++)
{ $y=$x+1;
$postkey = $postvars[$x];
$postval = $$postvars[$x];
$postipn.= "&" . $postkey . "=" . urlencode($postval);
$mailipn.= $postkey . " = " . $postval . "\r\n";
}

i then email myself a copy of $mailipn and it contains everything i need.
that part works fine.
however, is it possible to set a variable using the names that were
returned.
for example, paypal sends me back "business", so i would like to set the
value of $business
equal to the value from the paypal post.

normally i would do this:
@$business = $_POST['business'];
but since there are quite a few variables, and the names change (i.e.
shopping carts, etc.)
i would like to set them using the loop posted above (it returns them all).

using the loop above, the "business" line looks like this when echoed:
business = my********@paypal.com

so you see, it would nice to make a $business variable for later use in the
script
that contained my********@paypal.com

thanks.

paypal_post_vars_in_str = "";
foreach($paypal_post_arr as $key=>$value)
{
$value = urlencode(stripslashes($value));
paypal_post_vars_in_str .= "&$key=$value";
}

If you need the value of "business", you may use like
$paypal_post_arr['business']

Going one step further by using PHP's Variable Variables, you could do this:
<?
while (list($key, $val) = each($paypal_post_arr)) {
$$key = $val;
// ^^ - using a variable variable
}
?>

which results in $business being equal to whatever the actual value is.
The only problem is that you have to know what all the variable names
are in order to access them.
