How to sort two-dimensional arrays in PHP

How to sort two-dimensional arrays in PHP
Title, because this employee array is taken out from the database after processing, not directly removed, so you can not use the MySQL statement to sort, and this array is a two-dimensional array to save the record, the requirements are sorted by different fields, PHP Multisort can not be directly used, There seems to be no function of matrix conversion. So about how this array is sorted and solved

------Solution--------------------
Two steps.
1. Remove the member in the original array as the sort key into the new array. It's equivalent to indexing.
2. Sort the two arrays with Array_multisort
