I am revising my old code and replacing mysql with mysqli. Here is what I previously had for a database connection:
$db = mysql_connect('host', 'username', 'password');
and here is what I have now:
$db = new mysqli('host', 'username', 'password', 'database');
It seems to be working fine but I just wanted to ask if there are things I should be aware of in converting from mysql to mysqli.
