如何在数组中查找双精度值并组合双精度值

Question

我正在研究一种过滤双精度值的方法，如下面的示例所示，数组中存在的are乘积基本上是双精度的，应该合并（用合并的值创建一个新键）。

该产品应通过api_id组合。

//old current array
[products] => Array
    (
        [product_5c7fb5f72f9d5_192] => Array
            (
                [record_id] => 84721
                [api_id] => 192
                [amount] => 12
                [cost_price] => 3.36
            )
        [product_5c7fb5f72fe49_192] => Array
            (
                [record_id] => 84722
                [api_id] => 177
                [amount] => 1
                [cost_price] => 1.09
            )
        [product_5c7fb5f7301b2_192] => Array
            (
                [record_id] => 84724
                [api_id] => 192
                [amount] => 24
                [cost_price] => 6.72
            )
        [product_5c7fb5f7301b2_192] => Array
            (
                [record_id] => 84725
                [api_id] => 192
                [amount] => 24
                [cost_price] => 6.72
            )
    )

// this should be new new array
[products] => Array
    (
        [product_5c7fb5f72f9d5_192] => Array
            (
                [record_id] => 84721
                [api_id] => 192
                [amount] => 60//new value
                [cost_price] => 16.8//new value
            )
        [product_5c7fb5f72fe49_192] => Array
            (
                [record_id] => 84722
                [api_id] => 177
                [amount] => 1
                [cost_price] => 1.09
            )

    )

您可以使用<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> ：
