PHP accessing object's public properties as integers-CodePudding

I prefer to access associative arrays as object. i.e instead of $arr['item_title'] I prefer $arr->item_title. I have the following code that generates an array and with type casting I converted it into object:

public function getTotal()
{
    $total = 0;
    $items = [];
    $i = 0;
    $val = ($this->type == 'PUR')? 'cost': 'price';
    foreach($this->invoiceItems as $item){
        $items[$i]['item_title'] = $item->item->title;
        $items[$i]['item_id']    = $item->item_id;
        $items[$i]['unit_title'] = $item->unit->title;
        $items[$i]['unit_id']    = $item->unit_id;
        $items[$i]['cost']       = $item->itemUnit->cost;
        $items[$i]['price']      = $item->itemUnit->price;
        $items[$i]['qty']        = $item->qty;
        $total = $total   ($item->qty*$item->itemUnit->${'val'}) ;
        $i  ;
    }
    $output['total'] = $total;
    $output['items'] = (object) $items;
    $this->setTotal((object) $output);
    return $this->_total;
}

an example of the created object is:

<?= var_dump($model->total->items);?>

object(stdClass)[117]
  public '0' => 
    array (size=7)
      'item_title' => string 'Aspoceed tab.' (length=13)
      'item_id' => int 2
      'unit_title' => string 'Packet2s-10' (length=11)
      'unit_id' => int 3
      'cost' => float 9.25
      'price' => float 10
      'qty' => int 2
  public '1' => 
    array (size=7)
      'item_title' => string 'Aspoceed tab.' (length=13)
      'item_id' => int 2
      'unit_title' => string 'Strip10' (length=7)
      'unit_id' => int 2
      'cost' => float 4.75
      'price' => float 5.25
      'qty' => int 1
  public '2' => 
    array (size=7)
      'item_title' => string 'Apidone' (length=7)
      'item_id' => int 3
      'unit_title' => string 'Bottle Pack 12' (length=14)
      'unit_id' => int 6
      'cost' => float 118
      'price' => float 121.75
      'qty' => int 2

The problem is, I could not access the first public property of the above object directly i.e. without need to looping. For example:

$model->total->items->['0']->item_title
OR
$model->total->items->[0]->item_title
OR
$model->total->items[0]->item_title
OR
$model->total->items['0']->item_title

All these trying returns errors. Does it possible to access the object created in such way described above?

CodePudding user response：

I'm not sure why you're creating arrays in the first place if you want objects. Just create them as objects in the first place.

public function getTotal()
{
    $output = new StdClass;
    $total = 0;
    $items = new StdClass;
    $i = 0;
    $val = ($this->type == 'PUR')? 'cost': 'price';
    foreach($this->invoiceItems as $i => $item){
        $new_item = new StdClass;
        $new_item->item_title = $item->item->title;
        $new_item->item_id    = $item->item_id;
        $new_item->unit_title = $item->unit->title;
        $new_item->unit_id    = $item->unit_id;
        $new_item->cost       = $item->itemUnit->cost;
        $new_item->price      = $item->itemUnit->price;
        $new_item->qty        = $item->qty;
        $items->{$i} = $new_item;
        $total = $total   ($item->qty*$item->itemUnit->'val') ;
    }
    $output->total = $total;
    $output->items = (object) $items;
    $this->setTotal($output);
    return $this->_total;
}
