Thinkphp5.0 框架使用模型Model添加、更新、删除数据操作详解_php实例_

 $res = TestUser::create([ 'name' => 'zhao liu', 'password' => md5(123456), 'email' => 'zhaoliu@qq.com' ]); dump($res); 

 $userModel = new TestUser; $userModel->name = 'ya ya'; $userModel->email = 'yaya@139.com'; $res = $userModel->save(); dump($res);//影响的行数 dump($userModel->id);//新纪录的id 

 $userModel = new TestUser; $userModel->name = 'hei hei'; $userModel->email = 'heihei@139.com'; $userModel->yes = '不存在字段'; $res = $userModel->allowField(true)->save(); dump($res);//影响的行数 dump($userModel->id);//新纪录的id 

 $userModel = new TestUser; $data = array( ['name'=>'ga ga','email'=>'gaga@sina.com'], ['name'=>'you you','email'=>'youyou@163.com'] ); //返回结果是个多维的数组 $res = $userModel->saveAll($data); //如果需要得到添加的数据的每个id，需要遍历 foreach($res as $v){ dump($v->id); } 

 $res = User::update([ 'id' => 2, 'email' => '121@qq.com' ]); //返回修改之后model的整个对象信息 dump($res); 

 $res = User::update([ 'email' => '123@qq.com' ],['id'=>2]); //返回修改之后model的整个对象信息 dump($res); 

 $res = User::update([ 'email' => '555@qq.com' ],function($query){ $query->where(['id'=>2]); }); //返回修改之后model的整个对象信息 dump($res); 

 $res = User::where('id','=',2)->update([ 'email'=>'666@qq.com' ]); //返回影响的行数 dump($res); 

 $model = User::get(2); $model->email = '777@qq.com'; $res = $model->save(); //返回影响的行数 dump($res); 

 $model = new User(); $res2 = $model->save([ 'email' => '999@qq.com' ],['id'=>2]); //返回影响的行数 dump($res2); 

 $model = new User(); $res = $model->save([ 'email' => '000@qq.com' ],function($query){ $query->where(['id'=>2]); }); //返回影响的行数 dump($res); 

 $model = new User(); $res = $model->saveAll([ ['id' => 2,'email' => '122@qq.com'], ['id' => 3,'email' => '123@qq.com'], ['id' => 4,'email' => '124@qq.com'] ]); //返回数组 dump($res); 

 //删除id为3的记录 $res = User::destroy(3); //返回影响的行数 dump($res); 

 //删除id为3的记录 $model = User::get(3); $res = $model->delete(); //返回影响的行数 dump($res); 

 //删除id为4的记录 $res = User::where('id','=',4)->delete(); //返回影响的行数 dump($res);
