Can you compare and update two stdClass arrays?

Question

I have two stdclass objects namely

stdClass Object
(
    [apple] => 10
    [orange] => 10
    [grape] => 10
    [banana] => 20
    [mango] => 30
)

stdClass Object
(
    [apple] => 15
)

Can I update apple like a normal array operation? Or is there another way to do so?

Also whats the difference between this and a normal array?

Answer 1

You would loop through them using a normal foreach loop:

$obj = new StdClass;

$obj->test = 1;
$obj->more_testing = 2;

foreach ($obj as $key => $value) {
    echo $key . ': ' . $value . '\n\n';
}

or you could cast them as an your objects as an array using (array).

Answer 2

See the official documentation on comparing objects:

When using the comparison operator (==), object variables are compared in a simple manner, namely: Two object instances are equal if they have the same attributes and values (values are compared with ==), and are instances of the same class.

When using the identity operator (===), object variables are identical if and only if they refer to the same instance of the same class.
