核心：array_multisort()函数
定义规则，升降序，排列数组
1 <?php 2 $arr = array( 3 array( 4 'id' => 5, 5 'time' => '2018-01-05' 6 ), 7 array( 8 'id' => 3, 9 'time' => '2018-01-03' 10 ), 11 array( 12 'id' => 1, 13 'time' => '2018-01-01' 14 ), 15 array( 16 'id' => 2, 17 'time' => '2018-01-02' 18 ), 19 array( 20 'id' => 4, 21 'time' => '2018-01-04' 22 ) 23 ); 24 $arrSort = array(); 25 foreach($arr AS $key => $value){ 26 foreach($value AS $k=>$v){ 27 $arrSort[$k][$key] = $v; 28 } 29 } 30 /** 31 $arrSort=Array 32 ( 33 [id] => Array 34 ( 35 [0] => 5 36 [1] => 3 37 [2] => 1 38 [3] => 2 39 [4] => 4 40 ) 41 [time] => Array 42 ( 43 [0] => 2018-01-05 44 [1] => 2018-01-03 45 [2] => 2018-01-01 46 [3] => 2018-01-02 47 [4] => 2018-01-04 48 ) 49 ) 50 */ 51 52 array_multisort($arrSort['time'], SORT_ASC, $arr); 53 print_r($arr);
