数组排序
$sort = array_column($list, ‘uv‘);
array_multisort($sort, SORT_DESC, $list);


数组分页（用tp分页）

$list_print = $list;
$count = count($list);
$page_num = 20;
$Page = new ThinkPage($count, $page_num);
$list = array_slice($list, $Page->firstRow, $Page->listRows);


根据数组中相同的某些指定的值去重

$list = 你查询出来得数据有重复值;
$result = array();
foreach ($list as $val) {
    $key = $val[‘app_id‘] . $val[‘app_name‘] . $val[‘date‘] . $val[‘pv‘] . $val[‘uv‘] . $val[‘new_user‘];
    if (!isset($result[$key])) {
        $result[$key] = $val;
    }
}
$list = array_values($result);
