php连接access如何改为php连接mysql

<?php

//ACCESS执行类
class db{

var $db_path ;

//构造数据库路径
function dbpath($str)
{
$this->db_path=$str;
return $this->db_path;
}

//建立链接
function connect()
{
$db_link="DRIVER=Microsoft Access Driver (*.mdb);DBQ=".$this->db_path;
$db_result=odbc_connect($db_link,"","");
return $db_result;
}

//建立方法
function query($SQL)
{
$db_result=$this->connect();
$rs=odbc_exec($db_result,$SQL);
return $rs;
}

//断开链接
function db_close()
{
return odbc_close($this->connect());
}
}

//实例化类
$db = new db();
$db->dbpath($config["dbpath"]);
$db->charpage="GB2312";

?>

$conn=$db->connect("localhost"轮橘);
mysql_select_db("核桐空database",$conn); //选择数据库，我默认了database
$rs=$db->query("set names gb2312");
