Quick solution, change these lines to the Sql Server data:

private static $dbtype = "sqlsrv"; //aquivo troca para sqlsrv
private static $host = "ip";
private static $port = "3306";
private static $user = "root";
private static $password = "";
private static $db = "banco";

private function connect() {
    try {
        $this->conexao = new PDO($this->getDBType() . ":Server=" . $this->getHost() . ";port=" . $this->getPort() . ";Database=" . $this->getDB(), $this->getUser(), $this->getPassword());
    } catch (PDOException $i) {
        //se houver exceção, exibe
        die("Erro: <code>" . $i->getMessage() . "</code>");
    }

    return ($this->conexao);
}

Solution slower but more extensible. It changes all private by protected, so classes that inherit their class can see and modify these methods, and all self :: by static :: (for you to change the value of properties and your child class to use modifying it). To better understand self :: and static :: click this link

Once these substitutions have been created, create a new class and use it to connect to the database

class sqlServerDatabase extends database
{
    private static $dbtype = "sqlsrv"; //aquivo troca para sqlsrv
    private static $host = "ip";
    private static $port = "3306";
    private static $user = "root";
    private static $password = "";
    private static $db = "banco";

private function connect() {
    try {
        $this->conexao = new PDO($this->getDBType() . ":Server=" . $this->getHost() . ";port=" . $this->getPort() . ";Database=" . $this->getDB(), $this->getUser(), $this->getPassword());
    } catch (PDOException $i) {
        //se houver exceção, exibe
        die("Erro: <code>" . $i->getMessage() . "</code>");
    }

    return ($this->conexao);
}
}

The second method allows you not to have to change your database class every time you connect to a new database, just inherit it. This is one of the principles of SOLID , more specifically O.

In case you do not find the driver, you should enable it in your php.ini, as it is Sql Server in general you will have to install the driver, I would start with this link
