PHP 2D array sorting, php 2D Array

PHP 2D array sorting, php 2D Array

I. Problems

The hvals values retrieved from Redis are sorted randomly (see https://github.com/phpredis/phpredis#hvals the order is random and corresponds to redis 'own internal representation of The set structure .), as a result, the frontend display is inconsistent with the value retrieved from the database, so the hvals value is sorted in descending order.

Ii. Method

It mainly uses PHP's array_multisort-to sort multiple arrays or multi-dimensional arrays

$ Unread_policy = $ this-> redis-> hvals ('ushark: unread: Permission Y: 3'); foreach ($ unread_policy as & $ val) {$ val = json_decode ($ val, true);} $ time = array_column ($ unread_notify, 'newest _ Time'); array_multisort ($ time, SORT_DESC, $ unread_notify );!!! Key !!! Print_r ($ unread_notify );
