In PHP, how do I iterate over objects in a memory-efficient way?

In PHP, you can iterate over objects in a memory-efficient way using the `foreach` loop. This approach is preferable because it avoids the overhead of creating additional copies of the object, ensuring that you use memory optimally.

Here's an example of how to iterate over an object in PHP:


    <?php
    class MyClass {
        public $property1 = 'Value 1';
        public $property2 = 'Value 2';
        public $property3 = 'Value 3';
    }
    
    $object = new MyClass();
    
    foreach ($object as $key => $value) {
        echo "$key: $value<br>";
    }
    ?>
