This is not entirely true.

The following code, which doesn't rely on register_globals will generate 
a Notice.

<?php
   error_reporting(E_ALL);
   echo $_POST['x'];
?>

However, slightly modified, it produces no Notices:

<?php
   error_reporting(E_ALL);
   echo @$_POST['x'];

   //Another -- better way

   if ($_SERVER['REQUEST_METHOD'] == "POST")
   {
      echo $_POST['x'];
   }
?>
