在 PHP 中向关联数组添加新键和值 - Adding new keys & values to Associative array in PHP?

Adding new keys & values to Associative array in PHP?

本文关键字：添加键和值数组关联 PHP | 更新日期: 2023-09-27

我正在构建一个网络爬虫来检查价格...所以我有 2 个数组，我正在尝试将数据合并到一个数组中。第一个数组称为$results，如下所示：

Array ( 
[0] => Array ( 
[id] => 0 
    [myTitle] => Product One text... 
    [myImage] => Some url...
    [myPrice] => My price
) 
[1] => Array ( 
[id] => 1 
    [myTitle] => Product Two text... 
    [myImage] => Some url...
    [myPrice] => My price
 ) 
)

第二个数组富有想象力地调用：$results 2：

Array ( 
[0] => Array ( 
    [amzId] => 0 
    [amzTitle] => Amazon Product One text... 
    [amzPrice] => Amazon price
) 
[1] => Array ( 
    [amzId] => 1
    [amzTitle] => Amazon Product Two text...
    [amzPrice] => Amazon price
 )  
)

我需要将第二个数组键和值添加到第一个数组中，其中 Id 和"amzId"是相同的。

Array ( 
[0] => Array ( 
[id] => 0 
    [myTitle] => Product One text... 
    [myImage] => Some url...
    [myPrice] => My price
    [amzId] => 0 
    [amzTitle] => Amazon Product One text... 
    [amzPrice] => Amazon price
) 
[1] => Array ( 
[id] => 1 
    [myTitle] => Product Two text... 
    [myImage] => Some url...
    [myPrice] => My price
    [amzId] => 1 
    [amzTitle] => Amazon Product Two text... 
    [amzPrice] => Amazon price
 ) 
)

我不知道如何最好地做到这一点。或者，如果我在获取数据（对于 $results 2 数组）时最好在 foreach 循环中将新的键和值添加到原始$results数组中，这样我就不需要第二个数组了？

任何帮助将不胜感激！

尝试使用此函数。

$arr3 = array_merge($arr1,$arr2);
