数组操作解决思路

数组操作

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->array (  'time' =&gt; '2012-03-05 13',  'type' =&gt; 'ETC56-605N',  'count' =&gt; '52',)array (  'time' =&gt; '2012-03-05 14',  'type' =&gt; 'ETC56-605N',  'count' =&gt; '8',)array (  'time' =&gt; '2012-03-05 14',  'type' =&gt; 'ETC56-542N',  'count' =&gt; '39',)array (  'time' =&gt; '2012-03-05 15',  'type' =&gt; 'ETC56-542N',  'count' =&gt; '41',)array (  'time' =&gt; '2012-03-05 15',  'type' =&gt; 'ETC61-560N',  'count' =&gt; '10',)

如何变成array(time=>array(type=>count))这种形式？

------解决方案--------------------
这样？

PHP code

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