Description:
------------
Hello,

the prototype of PDOStatement::fetchObject() say that the first
parameter ($class_name) is required.

But you can call it without specifying this parameter, and without any
error.

So, witch is wrong ?

Reproduce code:
---------------
<?php
// With E_STRICT this produce an error because $class_name is set as
optional here. 
class myPDOStatement extends PDOStatement
{
    protected function __construct()
    {
    }

    public function fetchObject( $class_name = NULL, $ctor_args = NULL
)
    {
        return parent::fetchObject();
    }
}

echo PHP_EOL;
// To verify the current prototype : 
Reflection::export(new ReflectionMethod('PDOStatement',
'fetchObject'));

$db = new PDO('sqlite::memory:');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$db->exec("create table test ( id integer not null )");
$db->exec("insert into test values ( 5 )");

// But as you can see, $class_name is not required
if( $res = $db->query( "select id from test" ) ){
    while( $row = $res->fetchObject() ){
        var_dump( $row );
    }
}

Expected result:
----------------
Method [ <internal:PDO> public method fetchObject ] {

  - Parameters [2] {
    Parameter #0 [ <optional> $class_name ]
    Parameter #1 [ <optional> $ctor_args ]
  }
}

object(stdClass)#3 (1) {
  ["id"]=>
  string(1) "5"
}


Actual result:
--------------
Strict Standards: Declaration of secondPDOStatement::fetchObject()
should be compatible with that of PDOStatement::fetchObject() in
/home/dev-olivier/pdoTest.php on line 13

Method [ <internal:PDO> public method fetchObject ] {

  - Parameters [2] {
    Parameter #0 [ <required> $class_name ]
    Parameter #1 [ <optional> $ctor_args ]
  }
}

object(stdClass)#3 (1) {
  ["id"]=>
  string(1) "5"
}
