创建由数组组成的json对象

Question

In laravel I am getting list of articles from my query and later I am getting foreach of these articles number of comments and paths for all of their image files and videos. My goal is to make an array of json objects that would look like this:

[{
   id: id,
   title: title,
   summary: summary,
   comments: 'commentsCount',
   images: {
      path: 'path',
      path: 'path',
      path: 'path',
    }
 },
...
]

Not sure how to combine and make that kind of an array, this is my failed attempt:

$result = Article::where('publish', 1)->orderBy('created_at', 'desc')->paginate(15);
    $articles = [];

    foreach($result as $article){
      $articles[] = $article;
      $articles[]['comments'] = $article->comments()->count();

      foreach ($article->medias as $media){
        $articles[]['comments']['images'] = $media->path;
      }
    }

Updated code:

This is was the simplest solution that gave me wanted result:

$result = Article::where('publish', 1)->orderBy('created_at', 'desc')->paginate(15);

    foreach($result as $article){
      $articles[$article->id] = $article;
      $articles[$article->id]['comments'] = $article->comments()->count();
      $articles[$article->id]['medias'] = $article->medias()->get();
    }

    return $articles;

Answer 1

I suspect your problem is the way you use [] :

foreach($result as $article){
  $articles[] = $article;
  $articles[]['comments'] = $article->comments()->count();

  foreach ($article->medias as $media){
    $articles[]['comments']['images'] = $media->path;
  }
}

Every time you write $articles[] ... = ... you append a brand new element to the end of the array.

If you want to append one element and then append subelements you need a different approach:

1. Specify an index inside the brackets (which you can be a variable).

2. Compose the element first into a temporary variable, append it once at the end of the loop iteration.
