本文实例讲述了Yii2.0框架模型添加/修改/删除数据操作。分享给大家供大家参考，具体如下：
添加数据
|
1
2
3
4
5
6
|
$user = new User();$user->name = 'zhang';$user->age = 28;$data = $user->save();//添加数据$data = $user->insert();//添加数据$id = $user->attributes['id'];//获取当前添加数据后的自增id |
修改数据
|
1
2
3
4
5
6
|
$user = $User::findOne(1);$user->name = 'zhang';$data = $user->update();//修改$data = $user->save();//修改//修改单个字段$data = Uesr::updateAllCounters(['name' => 'li'],['id' => 1]);//参数1为要修改的字段，参数2为修改条件 |
删除数据
|
1
2
3
4
5
6
7
8
9
10
|
//删除数据$user = User::find()->where(['id' => 2])->one();//获取id为2的数据$data = $user->delete();//删除数据$uer = User::find()->where(['id' => 2])->all();//获取id为2的数据$data = $user[0]->delete();//删除数据//删除所有数据$user = User::deleteAll();$user = User::deleteAll('id=2');//删除id为2的数据//多个条件删除$data = User::deleteAll('id>:id AND num<:num',[':id' => 2,':num' => 100]); |
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
