多维数组中相同元素相加问题
本帖最后由 myths621 于 2013-03-19 12:04:11 编辑 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
)
),
);
$t = array();
foreach ($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>";
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
)
)
)
)
)
