Merging PHP Objects

Given two objects of same class, merge both objects into a single object.

class MyClass {} 
  
$objectA = new MyClass(); 
$objectA->a = 1; 
$objectA->b = 2; 
$objectA->d = 3; 
  
$objectB = new MyClass(); 
$objectB->d = 4; 
$objectB->e = 5; 
$objectB->f = 6; 
 
// Using array_merge
$obj_merged = (object) array_merge((array) $objectA, (array) $objectB); 
print_r($obj_merged);
stdClass Object
(
    [a] => 1
    [b] => 2
    [d] => 4
    [e] => 5
    [f] => 6
)

// Using array union operator
$obj_union = (object)((array) $objectA +(array) $objectB);        
print_r($obj_union);
stdClass Object
(
    [a] => 1
    [b] => 2
    [d] => 3
    [e] => 5
    [f] => 6
)
