利用yii2分页插件，成对取出数组数据

数组太大不好处理，切割出来处理

$ids = [1, 2, 3, 4, 5, 6, 7, 8, 9];
$count = count($ids);
$size = 2;
$pages = new Pagination(['totalCount' => $count, 'defaultPageSize' => $size]);

for ($i = 1; $i <= $pages->pageCount; $i++) {
$idArr = array_slice($ids, ($i - 1) * $size, $size);
    var_export($idArr);
}
