Question

我有以下数组，该数组的第一项的数量为3，其余的数量为1。这些数字是动态的。

Array
(
    [0] => Array
        (
            [id] => 39235995
            [quantity] => 3
            [price] => 2.81
        )

    [1] => Array
        (
            [id] => 39236029
            [quantity] => 1
            [price] => 2.952
        )

    [2] => Array
        (
            [id] => 39236015
            [quantity] => 1
            [price] => 3.333
        )

    [3] => Array
        (
            [id] => 39235997
            [quantity] => 1
            [price] => 2.667
        )

)

如何将其更改为以下输出？那么，第一个数量为3的商品现在被分成3个数组商品，每个商品的数量都设为一个？

Array
(
    [0] => Array
        (
            [id] => 39235995
            [quantity] => 1
            [price] => 2.81
        )

    [1] => Array
        (
            [id] => 39235995
            [quantity] => 1
            [price] => 2.81
        )

    [2] => Array
        (
            [id] => 39235995
            [quantity] => 1
            [price] => 2.81
        )
        
    [3] => Array
        (
            [id] => 39236029
            [quantity] => 1
            [price] => 2.952
        )

    [4] => Array
        (
            [id] => 39236015
            [quantity] => 1
            [price] => 3.333
        )

    [5] => Array
        (
            [id] => 39235997
            [quantity] => 1
            [price] => 2.667
        )

)

Answer 1

您可以循环遍历原始arr并将内容推入第二个数组。如果数量> 1，则可以创建一个循环，为每个数量推送项目。像这样：

if/else

请注意，代码希望您的原始数组称为$ arrA
