Without doing the rewrite for you, start by changing mysql to mysqli, in the code.

The connection signature changes to this:

mysqli_connect($mysql_host, $mysql_user, $mysql_pass, $mysql_db);

Also, I would move these to you mysql.conf file, it will save you 3 queries with every connection.

mysql_query("SET NAMES UTF8");
mysql_query("SET collation_connection = 'utf8_general_ci'");
mysql_query("SET sql_mode=''");

and you can remove this, as it's now part of the connection signature, saving another query with every connection.

mysql_select_db($mysql_db) or die('dbconn: mysql_select_db: ' + mysql_error());

Also, you will need to pass the database connection to mysqli_query like:

mysqli_query($db, $query);

You can make the $db connection a global or fetch it as needed.
