本文例項講述了laravel框架資料庫配置及操作資料庫。分享給大家供大家參考，具體如下：

laravel 資料庫配置

資料庫配置檔案為專案根目錄下的config/database.php

//預設資料庫為mysql
'default' => env('DB_CONNECTION', 'mysql'), 
'mysql' => [
'driver' => 'mysql',
'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' => '',
'strict' => true,
'engine' => null,
],

發現都在呼叫env函式，找到env檔案，即根目錄下的.env檔案，

開啟修改配置引數

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

修改為本地的資料庫資訊：

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=laravel
DB_USERNAME=root
DB_PASSWORD=123456

laravel 操作資料庫

建立student控制器，控制器程式碼

namespace App\Http\Controllers;
use Illuminate\Support\Facades\DB;
class StudentController extends Controller
{
  //新增
  public function addstudent(){
    $student = DB::insert('insert into student(name,age,gender) values(?,?,?)',['張三',12,2]);
    var_dump($student);//成功返回bloo值true
  }
  //獲取
  public function getall(){
//    $student = DB::select('select * from student');
    $student = DB::select('select * from student where id>?',[1]);
    return $student;//陣列
  }
  //修改
  public function updstudent(){
    $student = DB::update('update student set age= ? where name=?',[10,'張三']);
    var_dump($student);//成功返回bloo值true
  }
  //修改
  public function delstudent(){
    $student = DB::delete('delete from student where id=?',[10]);
    var_dump($student);
  }
}

注意 laravel中return true會報錯：

(1/1) UnexpectedValueException
The Response content must be a string or object implementing __toString(), "boolean" given.
