我想对数组里的uploadTime进行重新排列，代码如下
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 |
<?php $array=Array ( '0' => Array ( 'Name' => 'Anan Ryoko - Refrain.mp3', 'fullName' => 'Anan Ryoko - Refrain.mp3', 'length' => '6437585', 'uploadTime' => '1422975265', ), '1' => Array ( 'Name' => 'Andemund Orchestra - 梦中的婚礼.mp3', 'fullName' => 'Andemund Orchestra - 梦中的婚礼.mp3', 'length' => '1647776', 'uploadTime' => '1422975357', ), '2' => Array ( 'Name' => 'Ashram - Elizabeth.mp3', 'fullName' => 'Ashram - Elizabeth.mp3', 'length' => '1865495', 'uploadTime' => '1422975376', ), '3' => Array ( 'Name' => 'Bandari - 山溪.mp3', 'fullName' => 'Bandari - 山溪.mp3', 'length' => '3304113', 'uploadTime' => '1422975391', ), ); foreach($array as $key => $row){ $uploadTime[$key] = $row['uploadTime']; } array_multisort($uploadTime,SORT_DESC,$array); print_r ($array); |
输出
