Thinkphp5.0 框架使用模型Model添加、更新、删除数据(2)

$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);
