Comece pegando uma apostila básica de PHP...

Tem que fazer a conexão com o banco de dados, para tanto

//Faz a query
$sql = mysql_query("SELECT id FROM usuarios WHERE id ='3'");

//Pega o resultado
$dado = mysql_result($sql,'0','id');

Ali onde diz que tem que fazer a conexão você deve usar:

http://br.php.net/mysql_connect <- Para fazer a conexão

http://br.php.net/mysql_select_db <- Para seleciona o BD que será usado
