How insert associative array inside another array? PHP

Question

Why I can't insert an associative array inside another array? How can I do that? [PHP]

I try get somenthing like this:

    [0] => ['name' => 'namedperson' , 'type' => 'text' ,'id'=>'ahushaus29293' ]  
    [1] => [...] 
    ...

Example:

public function getArrayWithCustomFields($boardId, $client){
    $customFields = $client->getBoardCustomFields($boardId);
    foreach($customFields as $customField){
        array_push($array_custom_fields, array('name' => $customField->name, 'type' => $customField->type, 'id' => $customField->id));
    }
    return $array_custom_fields;
}

@ArSeN They're not trying to merge arrays, they want a 2-dimensional array. I think their code should work. — Barmar

My bad! @OP - what result are you getting instead of what you are trying to achieve? — ArSeN

You should initialize $array_custom_fields, as well as, check if the returned value from getBoardCustomFields is an array.

public function getArrayWithCustomFields($boardId, $client)
{
    // Init the array
    $array_custom_fields = [];
    $customFields = $client->getBoardCustomFields($boardId);

    // Check if the returned value from $client->getBoardCustomFields() is an array.
    if (is_array($customFields))
    {
        foreach($customFields as $customField) {
            array_push(
                $array_custom_fields,
                [
                    'name' => $customField->name,
                    'type' => $customField->type,'id' => $customField->id
                ]
            );
        }
    }

    return $array_custom_fields;
}

P.S: it's a good practice to always initialize your variables in PHP even tho it doesn't force you to do it.

Why "it's a good practice to always initialize your variables in PHP"? Is there a specific reason?
