Description:
------------
If passing NULL parameters in mysqli::__construct, as they are by default, the values are not actually taken from php.ini (or apache conf) file.

Tested with both 5.1.6 and 5.2 latest snapshot.

Reproduce code:
---------------
virtual host conf:
php_admin_value "mysqli.default_host" zorro
php_admin_value "mysqli.default_user" rootf
php_admin_value "mysqli.default_pw" ff

<?
$m = new mysqli(); echo mysqli_connect_error(), "\n";
$m = new mysqli(null); echo mysqli_connect_error(), "\n";
$m = new mysqli(null, null); echo mysqli_connect_error(), "\n";
$m = new mysqli(null, null, null); echo mysqli_connect_error(), "\n";
?>

Expected result:
----------------
Access denied for user 'rootf'@'zorro' (using password: YES) 
Access denied for user 'rootf'@'zorro' (using password: YES)
Access denied for user 'rootf'@'zorro' (using password: YES)
Access denied for user 'rootf'@'zorro' (using password: YES)

Actual result:
--------------
[empty]
Access denied for user 'rootf'@'localhost' (using password: YES) 
Access denied for user 'ODBC'@'localhost' (using password: YES) 
Access denied for user 'ODBC'@'localhost' (using password: NO)

NULL values passed as parameter to mysqli::__construct() have a special meaning, which are described in the docs.
 [2006-10-02 09:04 UTC] camka at email dot ee 
This does not describe, why the first case does not give an error at all, even if the host is not reachable or does not exist:

$m = mysqli(); // with no parameters

Calling the constructor without any argument is like calling mysqli_init() to create a mysqli object, it does not try to connect at all in this case but waits for an explicit call to mysqli::connect() or mysqli::real_connect() which allows to set mysqli::options() before connecting

Reclassified as documentation bug as the documentation on the mysqli constructor is not clear about this.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
