Description:
------------
require_once "DB.php";
$host = 'mysql.positive-internet.com';
$host = 'testhost.com';
$user = 'user1';
$pass ='mjasds';
$db_name ='dbtest';

$dsn = "mysql://$user:$pass@$host/$db_name";
$conn = &DB::connect($dsn);

if (DB::isError($conn)) 
{    
    echo 'Standard Message: ' . $conn->getMessage() . "\n";
    echo 'Standard Code: ' . $conn->getCode() . "\n";
    echo 'DBMS/User Message: ' . $conn->getUserInfo() . "\n";
    echo 'DBMS/Debug Message: ' . $conn->getDebugInfo() . "\n";
}

Reproduce code:
---------------
require_once "DB.php";
$host = 'mysql.positive-internet.com';
$host = 'testhost.com';
$user = 'user1';
$pass ='mjasds';
$db_name ='dbtest';

$dsn = "mysql://$user:$pass@$host/$db_name";
$conn = &DB::connect($dsn);

if (DB::isError($conn)) 
{    
    echo 'Standard Message: ' . $conn->getMessage() . "\n";
    echo 'Standard Code: ' . $conn->getCode() . "\n";
    echo 'DBMS/User Message: ' . $conn->getUserInfo() . "\n";
    echo 'DBMS/Debug Message: ' . $conn->getDebugInfo() . "\n";
}

Expected result:
----------------
would set a $conn as a usable connection object for mysql database

Actual result:
--------------
Standard Message: DB Error: extension not found Standard Code: -25 DBMS/User Message: [DB Error: extension not found] ** mysqli://user1:mjasds@testhost.com/dbtest DBMS/Debug Message: [DB Error: extension not found] ** mysqli://user1:mjasds@testhost.com/dbtest
