    $username = "root";
    $password = "sa";        

$phpConnect = mysqli_connect($host, $username, $db, $password);
    //checking the if connection.    
 if($phpConnect === false)
   {
      die("Error: Could not establish connection.".mysqli_connect_error());
   }
 ?>

Answer 1

The right syntax is: mysqli_connect("myhost","myuser","mypassw","mybd")

so try:

$phpConnect = mysqli_connect($host, $username, $password, $db);

refer this

Answer 2

Basically If you are the newbee in PHP so you should
1.first start the Xamp/Wamp service.
2.else db credentials for password should be $password = "".
