PHP编程：Yii2分页的使用及其扩展方法详解

PHP学习
use yii\data\Pagination;
$query = Article::find()->where(['status' => 1]);
$countQuery = clone $query;
$pages = new Pagination(['totalCount' => $countQuery->count()]);
$models = $query->offset($pages->offset)
  ->limit($pages->limit)
  ->all();
return $this->render('index', [
  'models' => $models,
  'pages' => $pages,
]);

PHP学习
use yii\widgets\LinkPager;
//循环展示数据
foreach ($models as $model) {
  // ......
}
//显示分页页码
echo LinkPager::widget([
  'pagination' => $pages,
])
