代码缩短

Question

这是我的第一个问题！

$champion1greenwards = 0;
$champion2greenwards = 0;
$champion3greenwards = 0;
$champion4greenwards = 0;
$champion5greenwards = 0;
$champion6greenwards = 0;
$champion7greenwards = 0;
$champion8greenwards = 0;
$champion9greenwards = 0;
$champion10greenwards = 0;


foreach($json as $arrays) {
      if (is_array($arrays)) {
        foreach($arrays as $arrayx) {
                foreach($arrayx as $arrayt) {
                        foreach($arrayt as $array) {

           if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '1') {
            $champion1greenwards++;
          }
               if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '2') {
            $champion2greenwards++;
          }
               if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '3') {
            $champion3greenwards++;
          }
               if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '4') {
            $champion4greenwards++;
          }
               if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '5') {
            $champion5greenwards++;
          }
               if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '6') {
            $champion6greenwards++;
          }
               if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '7') {
            $champion7greenwards++;
          }
               if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '8') {
            $champion8greenwards++;
          }
                   if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '9') {
            $champion9greenwards++;
          }
                       if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD' && $array['creatorId'] == '10') {
            $champion10greenwards++;
          }


        }
                }
        }
      }
    }
$championgreenwards = array($champion1greenwards,$champion2greenwards,$champion3greenwards,$champion4greenwards,$champion5greenwards,$champion6greenwards,$champion7greenwards,$champion8greenwards,$champion9greenwards,$champion10greenwards);

结果$ championgreenwards数组：

    Array
(
    [0] => 0
    [1] => 14
    [2] => 0
    [3] => 0
    [4] => 20
    [5] => 0
    [6] => 16
    [7] => 0
    [8] => 0
    [9] => 23
)

使用这段代码，我可以计算在地图中放置1,2,3,4,5,6,7,8,9,10个病房的次数，然后我用数据制作一个数组。但代码太长了，我不知道如何缩短这段代码。我找不到办法做到这一点。所以我来到这里。

Answer 1

这样的事情：

$greenwards = [];
foreach($json as $arrays) {
  if (is_array($arrays)) {
    foreach($arrays as $arrayx) {
      foreach($arrayx as $arrayt) {
        foreach($arrayt as $array) {
          if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD') {
            $greenwards[$array['creatorId']]++;
          }
        }
      }
    }
  }
}

Answer 2

$championgreenwards = array_fill(0, 10, 0);

foreach($json as $arrays) {
    if (!is_array($arrays)) {
        continue;
    }

    foreach($arrays as $arrayx) {
       foreach($arrayx as $arrayt) {
          foreach($arrayt as $array) {
              if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD') {
                  $championgreenwards[$array['creatorId']-1]++;
              }
          }
       }
    }
}

var_dump($championgreenwards);

或使用array_walk_recursive，如下所示：

array_walk_recursive($json, function ($array) use (&$championgreenwards) {
    if (!is_array($array) || !isset($array['type']) || !isset($array['wardType'])) {
        return;
    }

    if ($array['type'] == 'WARD_PLACED' &&  $array['wardType'] == 'SIGHT_WARD') {
        $championgreenwards[$array['creatorId']-1]++;
    }
});
