how do i edit this, so it links to mySQL database customer table?

 

if($userName=="janet" && $passWord=="qwerty") {

      // Assign userName to a session variable to track and use on each page

      $_SESSION['userName']=$userName;

      // Assign valid string to a session variable to track session validity

$_SESSION['status']="valid";

  }

  else {

      // error state

      $_SESSION['status']="invalid";

  }
