我有这个查询，给我以下php数组数据：

Question

Here is the foreach loop to get data in an array.

 foreach ($data['songsPlayList'] as $key => $value){
                    $data['playlistSongs'] = $this->_song->getSongsInPlaylist($value);
                    //var_dump($data['playlistSongs']);

                }

If I view the source , I will see this :

array(1) {
  [0]=>
  array(8) {
    ["id"]=>
    string(3) "121"
    [0]=>
    string(3) "121"
    ["artist"]=>
    string(12) "2face Idibia"
    [1]=>
    string(12) "2face Idibia"
    ["song_title"]=>
    string(13) "African Queen"
    [2]=>
    string(13) "African Queen"
    ["filename"]=>
    string(30) "2face Idibia-African Queen.mp3"
    [3]=>
    string(30) "2face Idibia-African Queen.mp3"
  }
}
array(1) {
  [0]=>
  array(8) {
    ["id"]=>
    string(3) "493"
    [0]=>
    string(3) "493"
    ["artist"]=>
    string(10) "Lucky Dube"
    [1]=>
    string(10) "Lucky Dube"
    ["song_title"]=>
    string(11) "Remember Me"
    [2]=>
    string(11) "Remember Me"
    ["filename"]=>
    string(26) "Lucky Dube-Remember Me.mp3"
    [3]=>
    string(26) "Lucky Dube-Remember Me.mp3"
  }
}

With this, I can only print out the results one array. So what I want to do is convert it to an array like this :

array(437) {
  [0]=>
  array(12) {
     ["id"]=>
    string(3) "121"
    [0]=>
    string(3) "121"
    ["artist"]=>
    string(12) "2face Idibia"
    [1]=>
    string(12) "2face Idibia"
    ["song_title"]=>
    string(13) "African Queen"
    [2]=>
    string(13) "African Queen"
    ["filename"]=>
    string(30) "2face Idibia-African Queen.mp3"
    [3]=>
    string(30) "2face Idibia-African Queen.mp3"
  }
  [1]=>
  array(12) {
      ["id"]=>
    string(3) "493"
    [0]=>
    string(3) "493"
    ["artist"]=>
    string(10) "Lucky Dube"
    [1]=>
    string(10) "Lucky Dube"
    ["song_title"]=>
    string(11) "Remember Me"
    [2]=>
    string(11) "Remember Me"
    ["filename"]=>
    string(26) "Lucky Dube-Remember Me.mp3"
    [3]=>
    string(26) "Lucky Dube-Remember Me.mp3"
  }
}

So I can do a php foreach loop to get all the result data. Any suggestions?

Answer 1

$data['playlistSongs'] = [];
foreach ($data['songsPlayList'] as $key => $value){
  $data['playlistSongs'][] = $this->_song->getSongsInPlaylist($value);
}
var_dump($data['playlistSongs']);

other solution:

$data['playlistSongs'] = array_map(function($song) use($this) {
  return $this->_song->getSongsInPlaylist($song);
}, $data['songsPlayList']);
