如何从本地计算机向远程数据库插入数据？

I am having shared server with cpanel.I have mysql database on server.I want to insert or update data to remote database by running php script on my local computer.Please give me solution. Thanks.

 /* mysql database properties */
    $host = 'mydomain.com'; // or I.P address of domain
    $user = 'database user name'; 
    $pass = 'database password';
    $database = 'database Name';
    $table = 'Table Name';

    /* Database Connection */
    $connection = mysql_connect($host,$user,$pass) or die (mysql_error());
    mysql_select_db($database, $connection) or die(mysql_error());
    $name = 'Amir Khan';
    $age = '27';
    /* Insert query */
    $sql_query = "INSERT INTO $table (name, age) VALUES ('$name', '$age');";
    $result = mysql_query($sql_query,$connection) or die(mysql_error());

    /*update query too same like above*/

    /* you can go mysqli or PDO  for better query structure*/
