使用相同的数字键合并两个PHP数组 [英] Merging two PHP arrays with same numeric key

问题描述

尝试用相同的数字键合并两个数组有一些困难.我已经尝试过array_merge()和array_merge_recursive()，但是似乎要做的就是附加第二个数组.

Having some difficulty trying to merge two arrays with the same numeric key. I have tried array_merge() and array_merge_recursive(), but all that seems to do is append the second array.

第一个数组的格式如下:

The first array has the following form:

Array
(
    [384] => Array
        (
            [name] => SomeMovieName1
            [age] => 12.2 hrs
            [IMDBLink] => 
            [IMDBRating] => 
            [coverArt] => 
        )

    [452] => Array
        (
            [name] => SomeMovieName2
            [age] => 13.1 hrs
            [IMDBLink] => 
            [IMDBRating] => 
            [coverArt] => 
        )

    [945] => Array
        (
            [name] => SomeMovieName3
            [age] => 13.6 hrs
            [IMDBLink] => 
            [IMDBRating] => 
            [coverArt] => 
        )
)

这是我要与第一个数组合并/合并的第二个数组:

And here is the second array I want to combine/merge with the first:

Array
(
    [384] => Array
        (
            [IMDBRating] => 7.2
            [IMDBLink] => http://www.imdb.com/LinkToMovie1
            [coverArt] => http://www.SomeLinkToCoverArt.com/1
        )

    [452] => Array
        (
            [IMDBRating] => 8.2
            [IMDBLink] => http://www.imdb.com/LinkToMovie2
            [coverArt] => http://www.SomeLinkToCoverArt.com/2
        )

    [945] => Array
        (
            [IMDBRating] => 6.2
            [IMDBLink] => http://www.imdb.com/LinkToMovie3
            [coverArt] => http://www.SomeLinkToCoverArt.com/3
        )
)

合并后，我希望结果是:

And after merging, I would like the result to be:

Array
(
    [0] => Array
        (
            [name] => SomeMovieName1
            [age] => 12.2 hrs
            [IMDBRating] => 7.2
            [IMDBLink] => http://www.imdb.com/LinkToMovie1
            [coverArt] => http://www.SomeLinkToCoverArt.com/1
        )

    [1] => Array
        (
            [name] => SomeMovieName2
            [age] => 13.1 hrs
            [IMDBRating] => 8.2
            [IMDBLink] => http://www.imdb.com/LinkToMovie2
            [coverArt] => http://www.SomeLinkToCoverArt.com/2
        )

    [2] => Array
        (
            [name] => SomeMovieName3
            [age] => 13.6 hrs
            [IMDBRating] => 6.2
            [IMDBLink] => http://www.imdb.com/LinkToMovie3
            [coverArt] => http://www.SomeLinkToCoverArt.com/3
        )
)

不确定是否是由于内部数组引起的问题，导致它不能直接与array_merge()或array_merge_recursive()一起使用.任何帮助将不胜感激，

Not sure if it's because of the inner arrays causing an issue that it won't work directly with array_merge() or array_merge_recursive(). Any help would be appreciated,

谢谢.

推荐答案

您可以尝试使用以下代码合并数组.代码生成所需的输出给您.我使用了您提供的示例数组:

You can try below code to merge array. Code generates desired output required to you. I have used sample array as given by you:

<?php
    $arr1=array(
        "384"=>array("name"=>"SomeMovieName1","age"=>"12.2 hrs","IMDBLink"=>"","IMDBRating"=>"", "coverArt"=>""),
        "452"=>array("name"=>"SomeMovieName2","age"=>"15.2 hrs","IMDBLink"=>"","IMDBRating"=>"", "coverArt"=>""),
        "954"=>array("name"=>"SomeMovieName3","age"=>"4.2 hrs","IMDBLink"=>"","IMDBRating"=>"", "coverArt"=>"")
    );
    $arr2=array(
       "384" => array("IMDBLink" => "7.2", "IMDBRating" => "http://www.imdb.com/LinkToMovie1", "coverArt" => "http://www.SomeLinkToCoverArt.com/1"),
       "452" => array("IMDBLink" => "5","IMDBRating" => "http://www.imdb.com/LinkToMovie2", "coverArt" => "http://www.SomeLinkToCoverArt.com/2"),
       "954"=>array("IMDBLink" => "8","IMDBRating" => "http://www.imdb.com/LinkToMovie3", "coverArt" => "http://www.SomeLinkToCoverArt.com/3")
    );
    $arr3 = array();
    foreach($arr1 as $key=>$val)
    {
         $arr3[] = array_merge($val, $arr2[$key]);
    }
    echo "<pre>";
    print_r($arr3);
?>
