In PHP, how do I deep copy objects in a memory-efficient way?

In PHP, deep copying an object means creating a new instance of an object and copying all properties over, ensuring that nested objects are also copied properly. This is especially useful when you want to modify a copy of an object without affecting the original object. Here's an example of how you can achieve this in a memory-efficient way using serialization and deserialization.


        <?php
        class Person {
            public $name;
            public $age;
            public $address;
    
            public function __construct($name, $age, $address) {
                $this->name = $name;
                $this->age = $age;
                $this->address = $address;
            }
        }
    
        function deepCopy($obj) {
            return unserialize(serialize($obj));
        }
    
        $original = new Person("John Doe", 30, "123 Main St");
        $copy = deepCopy($original);
    
        // Modify the copy
        $copy->name = "Jane Doe";
    
        echo $original->name; // Outputs: John Doe
        echo $copy->name;     // Outputs: Jane Doe
        ?>
