如何在与另一个值匹配的多维数组中找到最小值

Question

我有一个这样的多维数组，

y=[0;1]

我需要制作一个完全相似的数组，但仅包含每个年龄段（1,2和3）的最低价格值，对于2岁年龄段，将会有更多的价格（每个0-2和3-12岁）例如）基于不同的年龄范围（ageFrom和ageTo）。

其余的数组结构将保持不变。

输出数组将是这样，

[0] => Array ( [contractId] => 1 [pricingDetails] => Array ( 
                    [0] => Array ( [pricingName] => Price1 [priceId] => 1 [ageGroup] => 1 [ageFrom] => 13 [ageTo] => 50 [price] => 110.00 ) 
                    [1] => Array ( [pricingName] => Price2 [priceId] => 2 [ageGroup] => 1 [ageFrom] => 13 [ageTo] => 50 [price] => 77.00 ) 
                    [2] => Array ( [pricingName] => Price3 [priceId] => 3 [ageGroup] => 2 [ageFrom] => 3  [ageTo] => 12 [price] => 30.00 ) 
                    [3] => Array ( [pricingName] => Price4 [priceId] => 4 [ageGroup] => 2 [ageFrom] => 3 [ageTo] => 12 [price] => 30.00 ) 
                    [4] => Array ( [pricingName] => Price5 [priceId] => 5 [ageGroup] => 2 [ageFrom] => 3 [ageTo] => 12 [price] => 11.00 ) 
                    [5] => Array ( [pricingName] => Price6 [priceId] => 6 [ageGroup] => 2 [ageFrom] => 0 [ageTo] => 2 [price] => 0.00 ) 
                    [6] => Array ( [pricingName] => Price7 [priceId] => 7 [ageGroup] => 3 [ageFrom] => 51 [ageTo] => 149 [price] => 40.00 ) 
                    [7] => Array ( [pricingName] => Price8 [priceId] => 8 [ageGroup] => 3 [ageFrom] => 51 [ageTo] => 149 [price] => 30.00 ) 
                    [8] => Array ( [pricingName] => Price9 [priceId] => 9 [ageGroup] => 3 [ageFrom] => 51 [ageTo] => 149 [price] => 80.00 ) ) 
[1] => Array ( [contractId] => 2 [pricingDetails] => Array ( 
                    [0] => Array ( [pricingName] => Price1 [priceId] => 10 [ageGroup] => 1 [ageFrom] => 13 [ageTo] => 50 [price] => 120.00 ) 
                    [1] => Array ( [pricingName] => Price2 [priceId] => 11 [ageGroup] => 1 [ageFrom] => 13 [ageTo] => 50 [price] => 80.00 ) 
                    [2] => Array ( [pricingName] => Price3 [priceId] => 12 [ageGroup] => 2 [ageFrom] => 3 [ageTo] => 12 [price] => 35.00 ) 
                    [3] => Array ( [pricingName] => Price4 [priceId] => 13 [ageGroup] => 2 [ageFrom] => 3 [ageTo] => 12 [price] => 35.00 ) 
                    [4] => Array ( [pricingName] => Price5 [priceId] => 14 [ageGroup] => 2 [ageFrom] => 3 [ageTo] => 12 [price] => 15.00 ) 
                    [5] => Array ( [pricingName] => Price6 [priceId] => 15 [ageGroup] => 2 [ageFrom] => 0 [ageTo] => 2 [price] => 0.00 ) 
                    [6] => Array ( [pricingName] => Price7 [priceId] => 16 [ageGroup] => 3 [ageFrom] => 51 [ageTo] => 149 [price] => 45.00 ) 
                    [7] => Array ( [pricingName] => Price8 [priceId] => 17 [ageGroup] => 3 [ageFrom] => 51 [ageTo] => 149 [price] => 35.00 ) 
                    ) ) ))

Answer 1

此OP的历史记录是不接受任何答案，但我还是会回答。我要做的是创建一个分组名称，以便我可以选择价格最低的年龄段。

我将为此创建一个临时容器。将它们分组后，在批次的末尾。我将其展平，然后用新分组的数组覆盖该数组。

这是我的主意：

then

这是一个示例fiddle

让我知道是否还有另一种方法。
