Question

$arr1 is an associative array of anonymus objects:

array
  15898 => 
    object(stdClass)[8]
      public 'date' => int

$arr2 is another associative array with two (or more, it’s not fixed) properties:

array
  15898 => 
    object(stdClass)[10]
      public 'fruits'
      public 'drinks'

I can’t find any function for intersect and content fusion when dealing with objects. Basically i’d like to obtain:

array
  15898 => 
    object(stdClass)[8]
      public 'date' => int
      public 'fruits'
      public 'drinks'

Question is: is this even possible?

Answer 1

If I understand you correctly :-

$key = 15898;
$a[$key] = (object) array('date'=>time());
$b[$key] = (object) array('date2'=>time());
$c[$key] = (object) array_merge(get_object_vars($a[$key]), 
                                get_object_vars($b[$key]));

var_dump($c);

The above is make use on get_object_vars to extract all the properties belong to object $a, $b,
and merge it to a new array, then do a casting to object

With this, you are able to assign all properties (public) from object $a, $b to $c
