使用一个多维关联数组对另一个多维数组进行计数或求和

我有两个具有相同键的多维关联数组。我需要根据另一个数组的需求计算/求和一个数组中的特定值。

我尝试了嵌套的foreach循环，但无法获取请求的结果。我已经尽我所能搜索了互联网，但没有成功。

这是我的代码无法按要求工作：

foreach ($b as $key => $value) {
  foreach ($a as $skey => $svalue) {
    if ($key == $skey) {
      foreach ($svalue[Season] as $ssvalue) {
        if ($value[Appearance] == $ssvalue) {
          $c[$key]['SeasonAppearances'][] = count($value[Appearance]);
        }
      }
    }
  }
}

第一个数组（提取）/ $ a

$a = Array ( 
        [Paul] => Array ( 
                [Season] => Array ( 
                        [0] => 2014 
                        [1] => 2015 
                        [2] => 2016 
                        ) 
                ) 
        [John] => Array ( 
                [Season] => Array ( 
                        [0] => 2012 
                        ) 
                ) 
    )

第二数组（提取）/ $ b

$b = Array ( 
        [Paul] => Array ( 
                [Appearance] => Array ( 
                            [0] => 2014 
                            [1] => 2014 
                            [2] => 2014 
                            [3] => 2014 
                            [4] => 2014 
                            [5] => 2014 
                            [6] => 2014 
                            [7] => 2014 
                            [8] => 2015 
                            [9] => 2015 
                            [10] => 2015 
                            ) 
                ) 
        [John] => Array ( 
                [Appearance] => Array ( 
                            [0] => 2012 
                            [1] => 2012 
                            [2] => 2012 
                            [3] => 2012 
                            ) 
                ) 
        )

请求的结果数组/ $ c

$c = Array ( 
        [Paul] => Array ( 
            [SeasonCounts] => Array ( 
                        [0] => 8 
                        [1] => 3 
                        [2] => 0 
                        ) 
            ) 
        [John] => Array ( 
            [SeasonCounts] => Array ( 
                        [0] => 4 
                        ) 
            ) 
    )

我想计算$ a中每个季节每个人与每个人匹配的出现次数，并创建结果数组。请注意，保罗在2016年没有出场。

这应该像您想要的那样计数

$c = array();
$helper = array();
foreach ($b as $key => $value) {

    $c[$key] = array();
    $c[$key]["SeasonCount"] = array();
    $helper[$key] = array();
    foreach ($value["Appearance"] as $key1 => $value1) {

        $position = array_search($value1, $helper[$key]);
        if (false !== $position) {
            $c[$key]["SeasonCount"][$position]++;
        } else {
            $helper[$key][] = $value1;
            $c[$key]["SeasonCount"][] = 1;
        }

    }}
