Answer 1

The easiest way i always handle this Where

 $con = mysqli_connect($serverName,$dbusername,$dbpassword);

3 steps replacement in the following order

1. All "mysql_select_db(" with "mysqli_select_db($con,"
2. All "mysql_query(" with "mysqli_query($con," and
3. All "mysql_" with "mysqli_".

This works for me everytime
