php codearray ( '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',)
如何变成array(time=>array(type=>count))这种形式？
------解决方案--------------------
这样？
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);
