结合阵列但保留钥匙？ [英] combining arrays but keep keys?

问题描述

我想两个阵列组合，但保留其键到位。

比如说，我有我的下面$ artist_ids数组：

 阵列
（
    [1] =＆GT;排列
    （
        [artist_id] =＆GT; 12291
        [ARTIST_NAME] =＆GT; Maroon 5的
    ）
）
 

和我有我的$ song_ids数组：

 阵列
（
[0] =＆GT;排列
    （
        [ID] =＆GT; 113064
        [标题] =＆GT;难以呼吸
        [artist_id] =＆GT; 12291
        [ARTIST_NAME] =＆GT; Maroon 5的
    ）[2] =＆GT;排列
    （
        [ID] =＆GT; 113065
        [标题] =＆GT;这份爱
        [artist_id] =＆GT; 12291
        [ARTIST_NAME] =＆GT; Maroon 5的
    ）[3] =＆GT;排列
    （
        [ID] =＆GT; 113066
        [标题] =＆GT;发抖
        [artist_id] =＆GT; 12291
        [ARTIST_NAME] =＆GT; Maroon 5的
    ）
}
 

现在，如果我用array_merge（$ artist_ids，$ song_ids），它看起来像它创建$ song_ids我的$ artist_ids的底部有一个新的阵列和图钉;全然不顾键 - $ artist_ids [1]是突然[0]，其余的拖影

。

我可以使用保持键到位？想我我的输出看起来像：

 阵列
（
[0] =＆GT;排列
    （
        [ID] =＆GT; 113064
        [标题] =＆GT;难以呼吸
        [artist_id] =＆GT; 12291
        [ARTIST_NAME] =＆GT; Maroon 5的
    ）
[1] =＆GT;排列
    （
        [artist_id] =＆GT; 12291
        [ARTIST_NAME] =＆GT; Maroon 5的
    ）[2] =＆GT;排列
    （
        [ID] =＆GT; 113065
        [标题] =＆GT;这份爱
        [artist_id] =＆GT; 12291
        [ARTIST_NAME] =＆GT; Maroon 5的
    ）[3] =＆GT;排列
    （
        [ID] =＆GT; 113066
        [标题] =＆GT;发抖
        [artist_id] =＆GT; 12291
        [ARTIST_NAME] =＆GT; Maroon 5的
    ）
}
 

解决方案

只需使用重载的 + 合并数组：

  $ new_array = $ artist_ids + $ song_ids;
 

在这里看到它在行动： HTTP：//$c$cpad.viper-7。 COM / 1bJAfH

I'm trying to combine two arrays but keep their keys in place.

For instance, I have my $artist_ids array below:

Array
(
    [1] => Array
    (
        [artist_id] => 12291
        [artist_name] => Maroon 5
    )
)

And I have my $song_ids array:

Array
(
[0] => Array
    (
        [id] => 113064
        [title] => Harder To Breathe
        [artist_id] => 12291
        [artist_name] => Maroon 5
    )

[2] => Array
    (
        [id] => 113065
        [title] => This Love
        [artist_id] => 12291
        [artist_name] => Maroon 5
    )

[3] => Array
    (
        [id] => 113066
        [title] => Shiver
        [artist_id] => 12291
        [artist_name] => Maroon 5
    )
}

Now, if I use array_merge($artist_ids, $song_ids), it looks like it creates a new array and tacks on $song_ids to the bottom of my $artist_ids; totally disregarding the keys -- $artist_ids[1] is suddenly [0] with the rest trailing after.

What can I use that keeps the keys in place? I'd like my output to look like:

Array
(
[0] => Array
    (
        [id] => 113064
        [title] => Harder To Breathe
        [artist_id] => 12291
        [artist_name] => Maroon 5
    )
[1] => Array
    (
        [artist_id] => 12291
        [artist_name] => Maroon 5
    )

[2] => Array
    (
        [id] => 113065
        [title] => This Love
        [artist_id] => 12291
        [artist_name] => Maroon 5
    )

[3] => Array
    (
        [id] => 113066
        [title] => Shiver
        [artist_id] => 12291
        [artist_name] => Maroon 5
    )
}

解决方案

Just use the overloaded + to merge the arrays:

$new_array = $artist_ids + $song_ids;
