php根据二维数组排序

<?php
$data = array(
  array(
    ‘id‘ => 5698,
    ‘first_name‘ => ‘Bill‘,
    ‘last_name‘ => ‘Gates‘,
  ),
  array(
    ‘id‘ => 4767,
    ‘first_name‘ => ‘Steve‘,
    ‘last_name‘ => ‘Aobs‘,
  ),
  array(
    ‘id‘ => 3809,
    ‘first_name‘ => ‘Mark‘,
    ‘last_name‘ => ‘Zuckerberg‘,
  )
);

//根据字段last_name对数组$data进行降序排列
$last_names = array_column($data,‘last_name‘);
array_multisort($last_names,SORT_DESC,$data);
var_dump($data);

原理：先获取二维数组中的某个值对应的数据，再根据multisort 关联排序，就能获取到排序完成的数据集
