将对象从一个对象数组追加到另一个对象数组

I have two Object arrays. "ID" from array 1 corresponds to the same as "media_id" in array 2 I need to add the "album_ids" of array 2 to array 1.

我有两个Object数组。数组1中的“ID”对应于数组2中的“media_id”，我需要将数组2的“album_ids”添加到数组1中。

Object 1;

对象1;

Array ( [0] => stdClass Object ( [ID] => 2482 [post_author] => 6 [post_date] => 2014-07-31 07:59:26) [1] => stdClass Object ( [ID] => 2483 [post_author] => 6 [post_date] => 2014-07-31 07:59:28)

数组（[0] => stdClass对象（[ID] => 2482 [post_author] => 6 [post_date] => 2014-07-31 07:59:26）[1] => stdClass对象（[ID] = > 2483 [post_author] => 6 [post_date] => 2014-07-31 07:59:28）

Object 2=

对象2 =

Array ( [0] => stdClass Object ( [album_id] => 52 [media_id] => 2482 ) [1] => stdClass Object ( [album_id] => 92 [media_id] => 2483 )

数组（[0] => stdClass对象（[album_id] => 52 [media_id] => 2482）[1] => stdClass对象（[album_id] => 92 [media_id] => 2483）

I need the end result to be:

我需要最终结果：

Array ( [0] => stdClass Object ( [ID] => 2482 [post_author] => 6 [post_date] => 2014-07-31 07:59:26 [album_id] => 52) [1] => stdClass Object ( [ID] => 2483 [post_author] => 6 [post_date] => 2014-07-31 07:59:28 [album_id] => 92)

数组（[0] => stdClass对象（[ID] => 2482 [post_author] => 6 [post_date] => 2014-07-31 07:59:26 [album_id] => 52）[1] => stdClass对象（[ID] => 2483 [post_author] => 6 [post_date] => 2014-07-31 07:59:28 [album_id] => 92）

Thank you for the help!!

As per your question, lets suppose you have two arrays of objects - array1 and array2.

根据您的问题，假设您有两个对象数组 - array1和array2。

aarry1 = Array( [0] => stdClass Object ( [ID] => 2482 [post_author] => 6 [post_date] => 2014-07-31 07:59:26) [1] => stdClass Object ( [ID] => 2483 [post_author] => 6 [post_date] => 2014-07-31 07:59:28)

aarry1 = Array（[0] => stdClass对象（[ID] => 2482 [post_author] => 6 [post_date] => 2014-07-31 07:59:26）[1] => stdClass对象（[ID ] => 2483 [post_author] => 6 [post_date] => 2014-07-31 07:59:28）

array2= Array ( [0] => stdClass Object ( [album_id] => 52 [media_id] => 2482 ) [1] => stdClass Object ( [album_id] => 92 [media_id] => 2483 )

array2 = Array（[0] => stdClass对象（[album_id] => 52 [media_id] => 2482）[1] => stdClass对象（[album_id] => 92 [media_id] => 2483）

Now try out this code.

现在试试这段代码。

$albumids = array();
foreach ( $array2 as $key => $val) {
 $albumids[$val->media_id] = $val->album_id;
}

if(!empty($albumids)) {
 foreach ( $array1 as $key => $val) {
  if(isset($albumids[$val->ID])) {
    $val->album_id = $albumids[$val->ID];
  }
 }
}

print_r($array1);

You would get the expected result

你会得到预期的结果

Edit: I had to correct the following line from: $val->albumid = $albumids[$val->id]; to $val->album_id = $albumids[$val->ID];

编辑：我必须更正以下行：$ val-> albumid = $ albumids [$ val-> id]; to $ val-> album_id = $ albumids [$ val-> ID];
