The mistake is in your select database line, you did mix it with mysql_* when you should use mysqli_*

Your should use mysqli_select_db for selecting database using mysqli_* extension.

Your final code would be something like this:

$connect = mysqli_connect($servername, $username, $password);
mysqli_select_db($connect, $dbname);
