PHP创建密钥=> foreach中的值对 [英] PHP create key => value pairs within a foreach

问题描述

我想在foreach的数组中创建键/值对.这是我到目前为止的内容:

I want to create a key-value pairs in an array within a foreach. Here is what I have so far:

function createOfferUrlArray($Offer) {
    $offerArray = array();

    foreach ($Offer as $key => $value) { 
        $keyval = array($key => $value[4] );

        array_push($offerArray,$keyval);
    }

    return $offerArray;
}   

如果我在foreach中声明该数组，它将在每次迭代时覆盖它，但是在foreach之外定义它也不起作用，并且会导致三重奏:

If I declare the array within the foreach, it will overwrites it on each iteration, but defining it outside the foreach doesn't work either and causes triplets:

array[0] => key => value
array[1] => key => value 

如何做到这一点，这样我只能得到这样的键值对?

How do I make it so I only get key-value pairs like this?

key => value
key => value

推荐答案

像这样吗?

foreach ($Offer as $key => $value) { 
  $offerArray[$key] = $value[4];
}
