php - OOPHP 连接两个数据库

Question

我需要知道的是如何同时连接两个数据库。 我正在做的是从一个数据库表中获取一些信息并将其传输到另一个数据库。

我已经尝试过以下方法。

public function sitelistingcron()
{

    $sqlk = mysql_query("SELECT * FROM customer_detail WHERE approvedforsite = 2 OR approvedforsite = 3");


    include_once('database2.php');
    $fet = new Dbase();
        $fet->Connect();
        $fet->DB();
    while($row = mysql_fetch_array($sqlk)){
        //ADD
        $this->customer_id = $row['customer_id'];
        $this->tradingname = $row['TradingName'];
        $this->phone        = $row['Phone'];
        $this->street       = $row['Street'];
        $this->city         = $row['City'];
        $this->state        = $row['State'];
        $this->postcode     = $row['PostCode'];
        $this->approved = $row['approvedforsite'];




        $this->description  = $row['Description'];

        if($this->approved = 2)
        {
            $sqk = mysql_query("INSERT INTO approved_business_info (id, tradingname, phonenumber, street, postcode, suburb, discription) VALUES ({$this->customer_id}, '{$this->tradingname}', '{$this->phone}', '{$this->street}', '{$this->city}', '{$this->postcode}', '{$this->description}') ON DUPLICATE KEY UPDATE id = {$this->customer_id}, tradingname ='{$this->tradingname}', phonenumber ='{$this->phone}', street = '{$this->street}', postcode = '{$this->postcode}', suburb = '{$this->city}', discription = '{$this->discription}'") or mysql_error();


        print "INSERT INTO approved_business_info (id, tradingname, phonenumber, street, postcode, suburb, discription) VALUES ({$this->customer_id}, '{$this->tradingname}', '{$this->phone}', '{$this->street}', '{$this->city}', '{$this->postcode}', '{$this->description}') ON DUPLICATE KEY UPDATE id = {$this->customer_id}, tradingname ='{$this->tradingname}', phonenumber ='{$this->phone}', street = '{$this->street}', postcode = '{$this->postcode}', suburb = '{$this->city}', discription = '{$this->discription}'";


        }

        //REMOVE
        if($this->approved = 3)
        {
            $sqk = mysql_query("DELETE FROM `approved_business_info` WHERE id = {$this->customer_id}");
        }
    }   
}

您可以使用 mysql_ 扩展来使用两个单独的数据库连接，只需跟踪连接资源并将其传递给每个 mysql_ 函数调用即可:

$db1 = mysql_connect(...);
$db2 = mysql_connect(...);

mysql_query('SELECT ...', $db1);
mysql_query('INSERT ...', $db2);

查看 http://www.php.net/mysql_connect 的文档以及其他 mysql_ 函数。
