1.修改配置文件/.nev
DB_HOST=127.0.0.1 //数据库地址 DB_PORT=3306 //数据库端口 DB_DATABASE=database //数据库名称 DB_USERNAME=root //数据库账号 DB_PASSWORD=root //数据库密码
2.开始测试是否连接成功
/App/Http/routes.php 路由代码如下（可以自定义）
Route::get(‘dbtest‘,‘Admin\[email protected]‘);
3.新建IndexController控制器
/App/Http/Controllers/IndexController 控制器代码如下（可以自定义）
<?php
namespace App\Http\Controllers\Admin;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\DB;
class IndexController extends Controller{
public function dbcc(){
$pdo=DB::connection()->getPdo();
dd($pdo);
}
}
4.浏览访问测试
浏览器访问http://127.0.0.1/index.php/dbtest 成功提示如下图
PDO {#123 ▼

}}
遇到常见问题;
1.如果你的数据库表有前缀怎么处理
1.1/config/database.php找打如下代码
‘mysql‘ => [ ‘driver‘ => ‘mysql‘, ‘host‘ => env(‘DB_HOST‘, ‘localhost‘), ‘database‘ => env(‘DB_DATABASE‘, ‘forge‘), ‘username‘ => env(‘DB_USERNAME‘, ‘forge‘), ‘password‘ => env(‘DB_PASSWORD‘, ‘‘), ‘charset‘ => ‘utf8‘, ‘collation‘ => ‘utf8_unicode_ci‘, ‘strict‘ => false, ‘engine‘ => null, ],
1.2修改成如下代码
‘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‘, ‘‘), ‘prefix‘ => env(‘DB_PREFIX‘, ‘‘), ‘charset‘ => ‘utf8‘, ‘collation‘ => ‘utf8_unicode_ci‘, ‘strict‘ => false, ‘engine‘ => null, ],
1.3配置文件/.nev修改成如下代码
DB_HOST=127.0.0.1 //数据库地址 DB_PORT=3306 //数据库端口 DB_DATABASE=database //数据库名称 DB_PREFIX=unics_ //数据库表前缀名称 DB_USERNAME=root //数据库账号 DB_PASSWORD=root //数据库密码
