有时，我们开发项目的时候需要用到多个数据库，在thinkphp中可以使用多个数据库连接，Laravel也可以。Laravel 连接多个数据库及使用方法
配置.env 文件
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=shop DB_USERNAME=root DB_PASSWORD=root DB_HOST_TEST=127.0.0.1 DB_PORT_TEST=3306 DB_DATABASE_TEST=picture_test DB_USERNAME_TEST=root DB_PASSWORD_TEST=root
配置 config/database.php
//默认
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => 'lv_',
'prefix_indexes' => true,
'strict' => false,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
'picture_test' => [
'driver' => 'mysql',
'host' => env('DB_HOST_TEST', '127.0.0.1'),
'port' => env('DB_PORT_TEST', '3306'),
'database' => env('DB_DATABASE_TEST', 'picture_test'),
'username' => env('DB_USERNAME_TEST', 'root'),
'password' => env('DB_PASSWORD_TEST', 'root'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],model实例(这个model将使用picture_test连接)
<?php
namespace App\Model;
use Illuminate\Database\Eloquent\Model;
class Test extends Model
{
// 数据库'database_test'中的test表
public $table = 'test';
public $timestamps = false;
protected $connection = 'picture_test';
}调用model实例
// 以下是调用方法 Test::get();
DB直接连接数据库
// 连接picture_test库
DB::connection('picture_test')->table('test')->where('id',1)->first();
