Code for sorting two-dimensional arrays in PHP by letter

Copy codeThe Code is as follows:
<? Php
/**
* Sort an two-dimension array by some level two items use array_multisort () function.
*
* SysSortArray ($ Array, "Key1", "SORT_ASC", "SORT_RETULAR", "Key2 "......)
* @ Author Chunsheng Wang <wwccss@263.net>
* @ Param array $ ArrayData the array to sort.
* @ Param string $ KeyName1 the first item to sort.
* @ Param string $ SortOrder1 the order to sort by ("SORT_ASC" | "SORT_DESC ")
* @ Param string $ SortType1 the sort type ("SORT_REGULAR" | "SORT_NUMERIC" | "SORT_STRING ")
* @ Return array sorted array.
