Add property foreach object with php

Question

I have two arrays object:

$seo_items      = collect($resource->items)->values();
$api_items      = collect($api_items)->values();

And, I want to iterate these elements and add the property size, which belongs to the $api_items array to the $seo_items array.

foreach($seo_items as &$seo_item)
{
     foreach($api_items as $item) 
     {

        if($item->article_id == $seo_item->article->article_erp_id) 
        {
             $seo_item->article->size == $item->size;
             $items_result[] = $seo_item;
        }

     }
}

The problem is that I can not assign this value, because php report this error:

Undefined property: stdClass::$size

How can I do this ?

Please show result set of $seo_items and api_items

Seems it is result of typing.
You have used == ( comparison operator), which is comparing with property which doesn't exist,instead of assigning the value.

 $seo_item->article->size == $item->size;

changing it to

 $seo_item->article->size = $item->size;

Should resolve your problem.
