if you dd($project); or var_dump($project) from within you foreach, are you getting the full response expected?

Also, how many arrays do you have inside $projects? More than one I guess.

You probably don't need the [0]. Your first array inside $projects may be set as 0, however, the others will be 1, 2, 3 etc.

First off, I would see if you are getting the results expected without marking the first [0] part of the element. In your array ($projects) you are saying that the array is 'marked' with a 0. If for example your array is more like:

projects => [
                    'proj1' => []
                 ]

...as an example, then you would use $project['proj1']->id. Its really how the array is labeled up and what your keys are.

You can also use a key as part of your array like this - Which will use the actual key and not a number:

foreach($projects as $key=>$project)
{
    $tagged_project_item[] = array(
        'id'    => ($project[$key]->id),
        'title' => $project[$key]->title,
        'text'  => $project[$key]->text,
        'extra' => $project[$key]->extra
    );
}

However, my guess is that this should work:

foreach($projects as $project)
{
    $tagged_project_item[] = array(
        'id'    => ($project->id),
        'title' => $project->title,
        'text'  => $project->text,
        'extra' => $project->extra
    );
}

It really depends on how you data is structured in the array. Hopefully that might make a little sense.

Thank you for your reply/explanation. When i diedump $project this is what i get: (and that is correct)

array(1) {
  [0]=>
  object(stdClass)#366 (4) {
    ["id"]=>
    int(129)
    ["title"]=>
    int(535)
    ["text"]=>
    int(536)
    ["extra"]=>
    int(537)
  }
}

I also already set it to $key, but didn't change anything.

When i try to remove the [0] or [$key] i will get the error "Trying to get property of non-object". Which makes sense according to the data structure.

But none of it works :/

I keep getting the error "Undefined offset: 0", and i don't understand why. When i debug $project[0] it has the output i would expect.

$projects[] = \DB::table('tblproject_items')->where('id', $tagged_project->id)->get();

foreach($projects as $project)
{
   $tagged_project_item[] = array(
       'id'    => ($project[0]->id),
       'title' => $project[0]->title,
       'text'  => $project[0]->text,
       'extra' => $project[0]->extra
   );
}

Any advice on what could be going wrong?

Looking at your WHERE clause and your [0]'s put everywhere, I would say that you expect only one project item to match. It also seems like you're using the primary key to filter. If you have a model for the project item, you should use

$projectItems[] = ProjectItem::find($tagged_project->id);

Then $projects would be an array of projectItems. You could also use

$projectItems[] = \DB::table('tblproject_items')->where('id', $tagged_project->id)->first();

Now your code would be at least simpler. Take advantage of the toArray function.

foreach($projectsItems as $item)
{
    $tagged_project_item[] = $item->toArray();
}

I don't understand why your code isn't working. Maybe the error is somewhere else.

may be this sounds crazy but $tagged_project_item[] is not an array defined, before the each bucle init it

$projects[] = \DB::table('tblproject_items')->where('id', $tagged_project->id)->get();

$tagged_project_item = array();

foreach($projects as $project)
{
    $tagged_project_item[] = array(
        'id'    => ($project[0]->id),
        'title' => $project[0]->title,
        'text'  => $project[0]->text,
        'extra' => $project[0]->extra
    );
}

cast $project as an array.

foreach($projects as (array)$project){

}
