Question

Here is mysqli_connect() as defined in the PHP manual:

mysqli_connect([ string $host = ini_get("mysqli.default_host")
               [, string $username = ini_get("mysqli.default_user")
               [, string $passwd = ini_get("mysqli.default_pw")
               [, string $dbname = ""
               [, int $port = ini_get("mysqli.default_port")
               [, string $socket = ini_get("mysqli.default_socket") ]]]]]] )

Should I just do this for all the arguments?:

class MyClass {
    private $conn;

    public function __construct($host = '') {
        if($host == '') {
            $host = ini_get('mysqli.default_host');
        }

        $this->conn = mysqli_connect($host);
    }
}

If I do that for all the method arguments will it correctly wrap mysqli_connect()? Is there a more elegant may to do it?

EDIT:

After seeing Francios’s answer and thinking about it a little more this seems like the best way to do it:

class MyClass {
    private $conn;

    public function __construct($host = '',
                                $username = '',
                                $passwd = '',
                                $dbname = '',
                                $port = 0,
                                $socket = '') {
        $this->conn = call_user_func_array('mysqli_connect', func_get_args());
    }
}

Would that wrap it correctly? The only thing that worries me is the $port because it is not a string.

Answer 1

You could use call_user_func_array assuming that your class expects the parameters to be the exact same as mysqli_connect.

class MyClass
{
  private $conn;

  public function __construct()
  {
    $this->conn = call_user_func_array('mysqli_connect', func_get_args());
  }
}

With that said, the more elegant way is simply to extend the MySQLi class:

class MyClass extends MySQLi
{
  // Custom functions that extend the functionality of MySQLi can go here.
}
