多维数组中相同元素相加有关问题

多维数组中相同元素相加问题

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

------解决方案--------------------
最后结果是怎么样的？ 贴一下。
------解决方案--------------------

$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
