array_multisort和动态变量选项 [英] array_multisort and dynamic variable options

问题描述

我正在尝试使用array_multisort对任何数组进行排序，并且一切正常.但是，根据脚本中的条件，我需要更改选项.所以到目前为止，我是这样的:

Im trying to sort any array with array_multisort and everything is working great. However, based on conditions in my script, I need to change the options. So What I have so far is this:

array_multisort(
 $sort1,SORT_ASC,
 $sort2,SORT_ASC,
 $sort3,SORT_ASC, 
 $arraytosort
);

我想拥有的是这样的东西:

and what I would like to have is something like this:

$dynamicSort = "$sort1,SORT_ASC,$sort2,SORT_ASC,$sort3,SORT_ASC,";

array_multisort(
 $dynamicSort, 
 $arraytosort
);

有什么建议吗?

推荐答案

您可以尝试使用

You could try to use call_user_func_array. But I've never tried it on a built-in function before. Here is an example:

$dynamicSort = "$sort1,SORT_ASC,$sort2,SORT_ASC,$sort3,SORT_ASC";
$param = array_merge(explode(",", $dynamicSort), array($arrayToSort))
call_user_func_array('array_multisort', $param)
