首次发帖,请假高手
我从redis中取出五维数组需要处理相加,如下
希望数据处理后,相同date前提下,area里相同的key所对应的click和traffic值相加,即0和1这两个大数组,date为201001的,area中12所对应的click和traffic处理后应该是12和50,8对应的是6和60,其他类推,求遍历或其他能处理成功的方法,感激不尽~!

回复讨论(解决方案)
最后结果是怎么样的? 贴一下。
结果如下,感谢关注
$a = array( 0 => array( 0=> array( "date" => "201201", "area"=> array( 12 => array( click => "12", traffic => "50" ) , 8=> array( click => "6", traffic => "60" ) ) ), 1=> array( "date" => "201202", "area"=> array( 12 => array( click => "8", traffic => "40" ), 8=> array( click => "5", traffic => "50" ) ) ) ) );
$t = array();foreach ($a as $k=>$v){ foreach ($v as $k1=>$v1) { $t[0][$k1]['date'] = $v1['date']; foreach ($v1['area'] as $k2=>$v2) { $t[0][$k1]['area'][$k2]['click'] += $v2['click']; $t[0][$k1]['area'][$k2]['traffic'] += $v2['traffic']; } }}echo "";print_r($t);echo "";
结果如下:Array( [0] => Array ( [0] => Array ( [date] => 201201 [area] => Array ( [12] => Array ( [click] => 12 [traffic] => 50 ) [8] => Array ( [click] => 6 [traffic] => 60 ) ) ) [1] => Array ( [date] => 201202 [area] => Array ( [12] => Array ( [click] => 8 [traffic] => 40 ) [8] => Array ( [click] => 5 [traffic] => 50 ) ) ) ))感谢四楼正解
