  ),
)

我发布了我的数组值。这个值是动态的。这是两个数组conditionalLogic和conditionalLogic2我想分配那些数组键conditionalLogic2存在，值应该分配给conditionalLogic。将conditionalLogic值分配到conditionalLogic2后，从我的数组列表中删除该键。

检查我试过这种方式但没有工作 -

// $data['values'] array I have posted above
foreach ($data['values'] as $products) {
    foreach ($products['product_attributes'] as $product_choices) {
        if (!empty($product_choices['conditionalLogic2']) && $product_choices['conditionalLogic'] == '') {
            $product_choices['conditionalLogic'] = $product_choices['conditionalLogic2'];
            unset($product_choices['conditionalLogic2']);
        }
    }
}
var_export($data['values']); exit;

请帮助我，并给我任何解决方案如何将数组值替换为另一个数组。

解决此问题的捷径是什么？

Answer 1

您的代码几乎是正确的，但您在foreach循环中扮演局部变量。您应该将它们绑定到原始数组项，如下所示：

img{
  display: inline-block;
  width: 40%;
  margin-right: 40px;
}
.right_column{
  display: inline-block;
}

如果当前函数范围结束，则可以省略foreach ($data['values'] as & $products) { foreach ($products['product_attributes'] as & $product_choices) { if (!empty($product_choices['conditionalLogic2']) && $product_choices['conditionalLogic'] == '') { $product_choices['conditionalLogic'] = $product_choices['conditionalLogic2']; unset($product_choices['conditionalLogic2']); } } } unset($products); unset($product_choices);。但是，您可以显式删除数组中的引用，以避免在同一范围内的某些代码中产生不良影响。即下面某处的unset会破坏你阵列的最后一个分支。

Answer 2

通常最好避免嵌套循环：

foreach ($data as &$datum) {
    if (!isset($datum['product_attributes'])) {
        continue;
    }

    $datum['product_attributes'] = array_map(function ($productAttribute) {
        if (
            !empty($productAttribute['conditionalLogic2']) 
            && empty($productAttribute['conditionalLogic'])
        ) {
            $productAttribute['conditionalLogic'] = $productAttribute['conditionalLogic2'];
            unset($productAttribute['conditionalLogic2']);
        }

        return $productAttribute;
    }, $datum['product_attributes']);
}

这里我使用array_map()函数直接分配新数组。

Here is working example.

Answer 3

@chinu实际上，您实际上只是在for循环中分配或更改范围有限的局部变量，所以在这种情况下，我们应该使用pass by reference。

请参阅以下代码，它将起作用：

foreach ($data['values'] as &$products) {
    foreach ($products['product_attributes'] as &$product_choices) {        
        if (!empty($product_choices['conditionalLogic2']) && $product_choices['conditionalLogic'] == '') {
            $product_choices['conditionalLogic'] = $product_choices['conditionalLogic

PHP将一个数组值分配给另一个数组
