How can PHP automatically set object references when storing them in different arrays?

When storing objects in different arrays in PHP, the references to the objects are not automatically set. To ensure that the references are maintained, you can use the `&` symbol when assigning the object to the array. This will create a reference to the object rather than a copy, ensuring that any changes made to the object in one array will be reflected in the other arrays as well. 

class MyClass {
    public $value;
}

$obj = new MyClass();
$obj->value = 5;

$array1[] = &$obj;
$array2[] = &$obj;

$obj->value = 10;

print_r($array1); // Output: Array ( [0] => MyClass Object ( [value] => 10 ) )
print_r($array2); // Output: Array ( [0] => MyClass Object ( [value] => 10 ) )
