摘要：laravel、TP3.2

TP中配置多个数据库连接

1、config.php中进行配置

if(APP_DEBUG){
    return array(
        'DB_TYPE'               =>  'sqlsrv',
        'DB_HOST'               =>  '127.0.0.1',
        'DB_NAME'               =>  'xxx',
        'DB_USER'               =>  'xxx',
        'DB_PWD'                =>  'xxx$',
        'DB_PORT'               =>  'xxx',
         'DB_TWO' => array(
            'DB_TYPE'               =>  'sqlsrv',
            'DB_HOST'               =>  'xxx',
            'DB_NAME'               =>  'xxx',
            'DB_USER'               =>  'xxx',
            'DB_PWD'                =>  'xxx',
            'DB_PORT'               =>  'xxx',
         ),

2、代码中使用

 M('table','prefix','DB_TWO')

laravel中配置多数据库

1、配置.env文件

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=root
DB_PASSWORD=

DB_HOST_CENTER=127.0.0.1
DB_PORT_CENTER=3306
DB_DATABASE_CENTER=database_center
DB_USERNAME_CENTER=root
DB_PASSWORD_CENTER=

2、配置config/database.php

'mysql' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'charset' => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix' => '',
        'strict' => false,
        'engine' => null,
],
'mysql_center' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST_CENTER', 'localhost'),
        'port' => env('DB_PORT_CENTER', '3306'),
        'database' => env('DB_DATABASE_CENTER', 'forge'),
        'username' => env('DB_USERNAME_CENTER', 'forge'),
        'password' => env('DB_PASSWORD_CENTER', ''),
        'charset' => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix' => '',
        'strict' => false,
        'engine' => null,
],

3、创建model

a、这个model将采用默认的'mysql'连接
class UserModel extends Model
{
        // 数据库'database'中的users表
        protected $table = "users";
}

b、 这个model将使用mysql_center连接
class UserModel extends Model
{
    // 数据库'dadtabase_center'中的users表
        protected $connection = 'mysql_center';
        protected $table = "users";

}
