Array in array in array

Question

I'm a bit struggling with the associative arrays in associative arrays. Point is that I always have to drill deeper in an array and I just don't get this right.

$array['sections']['items'][] = array (
      'ident'         =>  $item->attributes()->ident,
      'type'          =>  $questionType,
      'title'         =>  $item->attributes()->title,
      'objective'     =>  (string) $item->objectives->material->mattext,
      'question'      =>  (string) $item->presentation->material->mattext,
      'possibilities' =>  array (
          // is this even neccesary to tell an empty array will come here??
          //(string) $item->presentation->response_lid->render_choice->flow_label->response_label->attributes()->ident => (string) $item->presentation->response_lid->render_choice->flow_label->response_label->material->mattext
      )
);

foreach ($item->presentation->response_lid->render_choice->children() as $flow_label) {
    $array['sections']['items']['possibilities'][] = array (
        (string) $flow_label->response_label->attributes()->ident => (string) $flow_label->response_label->material->mattext
    );
}

So 'possibilities' => array() contains an array and if I put a value in it like the comment illustrates I get what I need. But an array contains multiple values so I am trying to put multiple values on the position $array['sections']['items']['possibilities'][]

But this outputs that the values are stores on a different level.

...
[items] => Array
   (
      [0] => Array
         (
            [ident] => SimpleXMLElement Object
               (
                  [0] => QTIEDIT:SCQ:1000015312
               )
            [type] => SCQ
            ...
            [possibilities] => Array
               (
               )
         )

      [possibilities] => Array
         (
            [0] => Array
               (
                  [1000015317] => 500 bytes
               )
            [1] => Array 
               ...

What am trying to accomplish is with my foreach code above is the first [possibilities] => Array is containing the information of the second. And of course that the second will disappear.

Your $array['sections']['items'] is an array of items, so you need to specify which item to add the possibilities to:

$array['sections']['items'][$i]['possibilities'][]

Where $i is a counter in your loop.

Right now you are appending the Arrays to [items]. But you want to append them to a child element of [items]:

You do:

$array['sections']['items']['possibilities'][] = ...

But it should be something like:

$array['sections']['items'][0]['possibilities'][] = ...

$array['sections']['items'] is an array of items, and as per the way you populate the possibilities key, each item will have it's own possibilities. So, to access the possibilities of the item that is being looped over, you need to specify which one from $array['sections']['items'] by passing the index as explained in the first answer. OR To make things simpler, you can try

Save the item array (RHS of the first =) to a separate variable instead of defining and appending to the main array at the same time.
Set the possibilities of that variable.
Append that variable to the main $array['sections']['items']

I have:

array[{IsChecked: true, SEC: 0, STP: 0},
      {IsChecked: ture ,SEC: 0, STP: 1},
      {IsChecked: false, SEC: 1 ,STP: 0}]

How to get each SEC where IsCheked value is true?
