我很确定这可以简化，但我不确定如何简化。任何帮助将不胜感激！

foreach($color_count as $k => $v) {

            if($k == '["White","Blue","Black","Red","Green"]') { $this->add($filteredCards['White-Blue-Black-Red-Green'], $diff); }

            else if($k == '["Black"]') { $this->add($filteredCards['Black'], $diff); }
            else if($k == '["Red"]') { $this->add($filteredCards['Red'], $diff); }

    }

看起来您的$k是一个 JSON 编码的数组，因此：

$array = json_decode($k);
$newKey = implode('-', $array);
$this->add($filteredCards[$newKey], $diff);
