Description:
------------
construct Class error when used 2 parameters or more ;

The first parameter can't used the Default value !!


Reproduce code:
---------------
class Base
{.....}
class system_login extends Base
{
   var $db_conn; 
   var $user_table = 'user';
  function system_login( $DB = "", $mode = "http" )
  {.....}
}
$a = new system_login ("","Form");

Expected result:
----------------
I found the $mode == "http" always ;
but it will be $mode == "Form" when construct this class;

if I used :    $a = new system_login ("ss","Form");
the $mode == "Form" is OK!

The first parameter can't used the Default value !!

this code can used under PHP4 , it OK always !

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try avoid embedding huge scripts into the report.

More for code :

// file base.inc
<?php
class Base
{ var $test;
  var $info;
 function test()
  { //...anything..
  }
}
?>
//this is other file
<?php
require_once("base.inc");
class system_login extends Base
{
   private $db_conn; 
   private $user_table = 'user';
  function system_login( $DB = "", $mode = "http" )
  {
  global $Global_DB_Connection;
   if (empty($DB)) 
    $this->db_conn = $Global_DB_Connection;
   else
    $this->db_conn = $DB;
   if ($mode == 'http')
    {
    if (!isset($_SERVER['PHP_AUTH_USER'])) {
   header('WWW-Authenticate: Basic realm="My Realm"');
   header('HTTP/1.0 401 Unauthorized');
   echo 'please login at first !';
   exit;
  } else {
   Base::sys_login($_SERVER['PHP_AUTH_USER'],$_SERVER['PHP_AUTH_PW']);
   // ...anything..
  }
  }
 else
{
//... something for Form submit to login ...
}  
}
}

$a = new system_login ("","Form");
?>

if changed the :
function system_login( $DB = "", $mode = "http" )
to
function system_login( $DB, $mode )
used the
$a = new system_login ("","Form");
or
$a = new system_login ("","");

The PHP5 told me all the parameters missing !!

if I used an object to $DB , like :
$a = new system_login ($Global_DB_Connection, "Form");
I found the "Form" can't transfer to $mode also !

Can't reproduce it with your code. Works fine.
