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
$a = array(
0 => array(
0=> array(
"date" => "201201",
"area"=> array(
12 => array(
click => "3",
traffic => "30"
)
)
),
1=> array(
"date" => "201202",
"area"=> array(
12 => array(
click => "8",
traffic => "40"
),
8=> array(
click => "5",
traffic => "50"
)
)
)
),
1 => array(
0=> array(
"date" => "201201",
"area"=> array(
12 => array(
click => "9",
traffic => "20"
),
8=> array(
click => "6",
traffic => "60"
)
)
),
1=> array(
"date" => "201202",
"area" => NULL
)
),
);
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~！
多维数组

最后结果是怎么样的？ 贴一下。

$t = array();
foreach ($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'] += $v2['traffic'];
}
}
}
echo "<pre>";
print_r($t);
echo "<pre>";
结果如下：
Array
(
[0] => Array
(
[0] => Array
(
[date] => 201201
[area] => Array
(
[12] => Array
(
[click] => 12
