In PHP, how do I deep copy traits with PHP 8+ features?

In PHP 8 and later, you can make use of the new features to deep copy traits effectively. Deep copying is essential when you want to ensure that all properties and contained objects are also copied, rather than just the references.

trait MyTrait { public $name; public function __clone() { $this->name = clone $this->name; // Deep copy name if it's an object } } class MyClass { use MyTrait; public function __construct($name) { $this->name = $name; } } // Demonstrating deep copy $object1 = new MyClass(new SomeObject("Original")); $object2 = clone $object1; // Modifying the clone $object2->name->value = "Modified"; echo $object1->name->value; // Outputs: Original
