Laravel框架实现多数据库连接操作详解

<?php
return array(
  'default' => 'mysql',
  'connections' => array(
    # Our primary database connection
    'mysql' => array(
      'driver'  => 'mysql',
      'host'   => 'host1',
      'database' => 'database1',
      'username' => 'user1',
      'password' => 'pass1'
      'charset'  => 'utf8',
      'collation' => 'utf8_unicode_ci',
      'prefix'  => '',
    ),
    # Our secondary database connection
    'mysql2' => array(
      'driver'  => 'mysql',
      'host'   => 'host2',
      'database' => 'database2',
      'username' => 'user2',
      'password' => 'pass2'
      'charset'  => 'utf8',
      'collation' => 'utf8_unicode_ci',
      'prefix'  => '',
    ),
  ),
);

Schema::connection('mysql2')->create('some_table', function($table)
{
  $table->increments('id'):
});

$users = DB::connection('mysql2')->select(...);

<?php
class SomeModel extends Eloquent {
  protected $connection = 'mysql2';
}

<?php
class SomeController extends BaseController {
  public function someMethod()
  {
    $someModel = new SomeModel;
    $someModel->setConnection('mysql2');
    $something = $someModel->find(1);
    return $something;
  }
}
