Cleaner way to do this?

[Robert Sossomon <robert_sossomon@xxxxxxxx>]

foreach ( $_POST as $key => $value )
{
 while ($key != "submit")
 {
  \$$key = $value;
  $addtocart .= ",'\$$key'";
 }
}

The problem is that it seems to be hanging at the while loop.  Is there a 
cleaner way to write the foreach loop so that it will dump out the "submit" key? 
 I've been trying different combinations, and am sure it is something simple I 
have boffed.

Thanks,
Robert
