如何使用php實現封裝數據庫的類文件

　　<?php

　　class dbname{ private $localhost; private $root; private $pass; private $db_name; public function __construct($localhost$root$pass$db_name){ $this>localhost=$localhost; $this>root=$root; $this>pass=$pass; $this>db_name=$db_name; $this>query(); } private function query(){ mysql_connect($this>localhost$this>root$this>pass); mysql_select_db($this>db_name); mysql_query("set names utf"); } } ?>
