Sample codes or sites will do. Im using MySQL Command Client by the way.

Answer 1

Why don't you use a mysql wrapper. It has functions to add/update/delete and a lot more utitlity functions to fasten your development time by about 40%. Ofcourse it is fully object-oriented solution.

Answer 2

You're looking for MySQLi. It's a built-in extension since PHP 5 that you may use to query a MySQL database for data.

$mysql = new MySQLi('localhost', 'username', 'password', 'database')
$mysql->query("SELECT * FROM users");

Answer 3

If you're build an app from scratch, I would recommend using a PHP MVC framework package, like CakePHP or CodeIgniter. They both include a database abstraction layer which normalizes standard database functionality and keeps you from having to write SQL statements. The beauty of this is that it also allows you to change your db type later, from MySQL to say PostgreSQL, with a simple configuration change.

If you can't use an MVC, check out ADODB, which is a standalone database abstraction class:

Adodb mentioned by wmpjmurray is a good choice. You could also just create your own class that extends PDO. There are a few examples of how other people have done this in the PHP Manual.
