本文实例讲述了php简单实现多维数组排序的方法。分享给大家供大家参考,具体如下:
之前在做一个功能的时候,必须要把数据放到二维数组里并且排序,然后上网找找解决思路,
这时候会用到array_multisort函数,array_multisort() 函数对多个数组或多维数组进行排序
先来看一个实例

<?php
$data = array (
0=> array ( 'one' =>34, 'two' => 'd' ),
1=> array ( 'one' =>45, 'two' => 'e' ),
2=> array ( 'one' =>47, 'two' => 'h' ),
3=> array ( 'one' =>12, 'two' => 'c' ),
4=> array ( 'one' =>15, 'two' => 'w' ),
5=> array ( 'one' =>85, 'two' => 'r' ),
);
foreach ( $data as $val ){
$key_arrays []= $val [ 'one' ];
}
array_multisort ( $key_arrays ,SORT_ASC,SORT_NUMERIC, $data );
var_dump( $data );

输出结果:按键值one排序,如下:

php 多维数组排序
下面来封装成函数方便使用

function my_array_multisort( $data , $sort_order_field , $sort_order =SORT_ASC, $sort_type =SORT_NUMERIC){
foreach ( $data as $val ){
$key_arrays []= $val [ $sort_order_field ];
}
array_multisort ( $key_arrays ,SORT_ASC,SORT_NUMERIC, $data );
rturn $data ;
}
