php 二维数组按某个字段排序

标签：amp path 字段 函数 数组 color com basename sftp 主要用到两个函数： 1.array_column() 返回输入数组中某个单一列的值。php版本5.5以后自带 2.array_multisort() 函数返回排序数组。您可以输入一个或多个数组。函数先对第一个数组进行排序，接着是其他数组，如果两个或多个值相同，它将对下一个数组进行排序。 参考：https://www.cnblogs.com/wenzheshen/p/9455554.html php 二维数组按某个字段排序 标签：amp path 字段 函数 数组 color com basename sftp 原文地址：https://www.cnblogs.com/clubs/p/13149780.htmlphp

$last_names = array_column($data, ‘filename‘);
array_multisort($last_names, SORT_ASC, $data);//SORT_ASC 按照上升顺序排序， SORT_DESC 按照下降顺序排序
