Array
id Name Age Language
1 Novel 16 90
2 Xiaomeng 18 93
2 Kitten 17 92
Question:
This is a table.
1: How to sort by age from smallest to largest?
2: How to sort by Chinese language from smallest to largest?
3: ID sorting is the default, so don’t use it╮(￣▽￣"")╭
Simply put, the associative array is sorted by a certain key.

Learn about this function: array_multisort()

function arr_sort($arr,$key_name){ $sort = array(); foreach ($arr as $key => $value) { $sort[$key] = $value["$key_name"]; } array_multisort($sort, SORT_ASC , $arr); return $arr; }
