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
<br />
$a = array(<br />
<br />
0 => array(<br />
<br />
0=> array(<br />
<br />
"date" => "201201",<br />
"area"=> array(<br />
12 => array(<br />
click => "3",<br />
traffic => "30"<br />
) <br />
)<br />
), <br />
<br />
1=> array(<br />
<br />
"date" => "201202",<br />
"area"=> array(<br />
12 => array(<br />
click => "8",<br />
traffic => "40"<br />
),<br />
8=> array(<br />
click => "5",<br />
traffic => "50"<br />
)<br />
)<br />
) <br />
<br />
),<br />
<br />
1 => array(<br />
<br />
0=> array(<br />
<br />
"date" => "201201",<br />
"area"=> array(<br />
12 => array(<br />
click => "9",<br />
traffic => "20"<br />
),<br />
8=> array(<br />
click => "6",<br />
traffic => "60"<br />
)<br />
)<br />
),<br />
<br />
1=> array(<br />
<br />
"date" => "201202",<br />
"area" => NULL<br />
)<br />
),<br />
<br />
<br />
);<br />
<br />
希望数据处理后，相同date前提下，area里相同的key所对应的click和traffic值相加，即0和1这两个大数组，date为201001的，area中12所对应的click和traffic处理后应该是12和50,8对应的是6和60，其他类推，求遍历或其他能处理成功的方法，感激不尽~！
多维数组
------解决方案--------------------最后结果是怎么样的？ 贴一下。
------解决方案--------------------$t = array();<br />
foreach ($a as $k=>$v)<br />
{<br />
foreach ($v as $k1=>$v1)<br />
{<br />
$t[0][$k1]['date'] = $v1['date'];<br />
foreach ($v1['area'] as $k2=>$v2)<br />
{<br />
$t[0][$k1]['area'][$k2]['click'] += $v2['click'];<br />
$t[0][$k1]['area'][$k2]['traffic'] += $v2['traffic'];<br />
}<br />
}<br />
}<br />
echo "<pre class="brush:php;toolbar:false">";<br />
print_r($t);<br />
echo "<pre class="brush:php;toolbar:false">";
结果如下：
<br>
Array<br>
(<br>
[0] => Array<br>
(<br>
[0] => Array<br>
(<br>
[date] => 201201<br>
[area] => Array<br>
(<br>
[12] => Array<br>
(<br>
[click] => 12 <div class="clear">
</div>
