Description:
------------
I have found en error in Polish documentation each function 
(http://pl.php.net/manual/pl/function.each.php)

Error is in line 

"while (list ($key, $val) = each (_POST)) {"

there should be 

"while (list ($key, $val) = each ($_POST)) {" 

Reproduce code:

echo "Warto?ci wys?ane metod? POST: <br />\n";
reset ($_POST);
while (list ($key, $val) = each (_POST)) {
   echo "$key => $val<br />\n";
}
