Description:
------------
get_resource_type() returns bool false on a valid resource handle.

Reproduce code:
---------------
<?php

$host = 'localhost';
$user = 'user';
$pass = 'pass';
$dbpn = 'database';

$connection = mysqli_connect ( $host, $user, $pass, $dbpn );

if ( ! $connection )
{
	echo 'bad connection';

	exit ();
}

var_dump ( get_resource_type ( $connection ) );

mysqli_close ( $connection );

?>



Expected result:
----------------
I expect...

string(unknown)


Because it seems that mysqli_() is not in the (List of Resource Types) supported. But it would be nice if mysqli_() and the rest of the database extensions that PHP supports were added to the (List of Resource Types) supported.





Actual result:
--------------
I get..

bool(false)

Which clearly states that $connection is not a valid resource, when it really is!
