二维数组排序可以用php内置函数

 1 php
 2 $arr = array(
 3         
 4             array('name'=>'zhangsan','age'=>26,'gender'=>'male','height'=>180),
 5             array('name'=>'zhangsan','age'=>21,'gender'=>'female','height'=>156),
 6             array('name'=>'zhangsan','age'=>59,'gender'=>'male','height'=>178)
 7     
 8     
 9         );
10 
11 
12 function array_sort($arr=array(),$key='',$sort=0){
13     
14     $arr_key = array();
15     foreach ($arr as $k=>$v) {
16         $arr_key[$k] = $v[$key];
17         
18     }
19     ($sort == 0)?asort($arr_key):arsort($arr_key); 
20     
21     $return_arr = array();
22     foreach ($arr_key as $k=>$v) {
23     
24     $return_arr[$k] = $arr[$k];
25         
26     }
27     
28     return $return_arr;
29 }
