phalcon 鏈接多個數據庫 phalcon multi-database

db:

//This service returns a MySQL database  
$di->set('dbMaster', function() {  
     return new \Phalcon\Db\Adapter\Pdo\Mysql(array(  
        "host" => "localhost",  
        "username" => "",  
        "password" => "",  
        "dbname" => ""  
    ));  
});  
  
//This service returns a PostgreSQL database  
$di->set('dbSlave', function() {  
     return new \Phalcon\Db\Adapter\Pdo\Mysql(array(  
        "host" => "localhost",  
        "username" => "",  
        "password" => "",  
        "dbname" => ""  
    ));  
}); 

　　

public function initialize()  
{  
    $this->setConnectionService('dbMaster');  
    //or  
    $this->setConnectionService('dbSlave');  
}  

　　

這是給出來的案例，在實際代碼環境，用的是默認生成的模板文件。

 

修改配置文件

'database' => array(  
    'adapter'     => 'Mysql',  
    'host'        => '127.0.0.1',  
    'username'    => 'root',  
    'password'    => 'toor',  
    'dbname'      => 'db1',  
    'charset'     => 'utf8',  
),  
'db2' => array(  
    'adapter'     => 'Mysql',  
    'host'        => '127.0.0.1',  
    'username'    => 'root',  
    'password'    => 'toor',  
    'dbname'      => 'db2',  
    'charset'     => 'utf8',  
),  

　　

$di->set('db', function () use ($config) {  
    return new DbAdapter($config->database->toArray());  
});  
$di->set('db2', function () use ($config) {  
    return new DbAdapter($config->db2->toArray());  

　　

在model中使用時，

class user  extends Model  
{  
    public function initialize()  
    {  
        $this->setConnectionService('db2');  
    }  
}
