數組操作解決思路

數組操作

PHP code

array (  'time' => '2012-03-05 13',  'type' => 'ETC56-605N',  'count' => '52',)array (  'time' => '2012-03-05 14',  'type' => 'ETC56-605N',  'count' => '8',)array (  'time' => '2012-03-05 14',  'type' => 'ETC56-542N',  'count' => '39',)array (  'time' => '2012-03-05 15',  'type' => 'ETC56-542N',  'count' => '41',)array (  'time' => '2012-03-05 15',  'type' => 'ETC61-560N',  'count' => '10',)

如何變成array(time=>array(type=>count))這種形式？

------解決方案--------------------
這樣？

PHP code

$arr = array(        array (          'time' => '2012-03-05 13',          'type' => 'ETC56-605N',          'count' => '52',        ),          array (          'time' => '2012-03-05 14',          'type' => 'ETC56-605N',          'count' => '8',        ),          array (          'time' => '2012-03-05 14',          'type' => 'ETC56-542N',          'count' => '39',        ),          array (          'time' => '2012-03-05 15',          'type' => 'ETC56-542N',          'count' => '41',        ),          array (          'time' => '2012-03-05 15',          'type' => 'ETC61-560N',          'count' => '10',        )   );foreach($arr as $array){        $newarr[$array['time']][$array['type']] += $array['count'];}print_r($newarr);
