您好我正在使用Laravel构建电子商务Web应用程序，对于我的产品，有三种类型的过滤器，例如：Color，Style，Industry，这些过滤器包含一些像这样的值：
color => red, green, blue yellow....
Style => Bold,Conservative,Elegant,Floral...
Industry => Agriculture & Farming, Animals & Pet Care,Art & Entertainment...
并且所有产品都具有所有三个过滤器，因此每个产品都具有每个过滤器的一些组合，例如 Product_1 =＆gt; blue，Floral，Agriculture＆amp;农即可。我没有在我的产品表中插入过滤器而不是我已经创建了所有可能组合的列表以及每个组合的id，所以总共有4000种组合的所有三种类型的过滤器所以在我的产品表中只使用像 filter_ID ，其中包含组合ID。
现在，当我展示产品时，我需要计算每个过滤器可用的项目，例如Agriculture＆amp;种植[使用此填充物的产品总数]。
在该组合列表中，我没有使用真正的过滤器名称而不是我为每个过滤器提供了一个Integer ID，如：
Agriculture & Farming = 1, Animals & Pet Care = 2, blue = 3....
所以现在我有三件事可以计算每个过滤器中的可用产品。
我试图计算使用循环，但是它没有返回正确的值我的样本数据很大所以我不能在这里插入我包含链接到我的php文件，在那里你可以找到所有数据以及我需要的结果。{{ 3}}
代码：
// This is all three fillters possible combination in this array 1st level array is a combination
//And in 2nd level array it conatins 4 items which are:
//1st item is Combination ID and
//2nd item is Interger value of actual Fillter (Industry)
//3rd item is Interger value of actual Fillter (Style)
//4th item is Interger value of actual Fillter (color)
// Using this for faster performance
