PHP二维数组排序问题详解(数组键值排序)
在php中数组排序一直是一个大家论证的话题,下面我来给各位朋友详细介绍关于在php中二维数组排序问题,有需要了解的数组排序的朋友可参考。
根据某个键值对二维数组进行排序是个常见问题,这里总结一个函数,可同时对两个键值分别排序,当然想要更多的话就自行解决吧。
但是如果需要排序的数组是一个二维数组,需要按照数组的键值排序,如下面这个二维数组,需要按照sort键名来排序,那么array_multisort() 就无法直接实现了:

代码如下 | 复制代码 |
|
这样array_multisort()不不能生效了,
我们可以对函数进行升级一下,根据指定键值进行排序
代码如下 | 复制代码 |
function array_sort($arr,$key1,$sort1='asc',$key2='',$sort2='asc'){ |
实例二
代码如下 | 复制代码 |
$array = array( $ShoppingList = array_sort($array,'price'); |
面是对$array这个二维数组按照'price'从低到高的排序。
