Description:
------------
---
From manual page: http://www.php.net/mysqli.connect-errno
---
i tested mysqli->$connect_errno.

This is written in docs "string $mysqli->connect_errno;".
meaning return type is string.
however, method returned integer.

Test script:
---------------
<?
//Test code
$this->objMySQLi = new mysqli(
   'localhost',
   'admin_hoge',
   'password_hoge',
   'hugeDatabase'
);
var_dump($this->objMySQLi->connect_errno);
exit;
?>

Expected result:
----------------
Test code showed var dump of some integer.
ex: int(0)
ex: int(1045)
