In PHP, how do I compare objects with PHP 8+ features?

In PHP 8 and later, comparing objects has been made easier and more efficient with the introduction of the `stdClass` and enhancements in the `==` and `===` operators. To compare objects, you can use these operators to check for equality or identity.

Here's how you can compare two objects in PHP:

<?php class User { public $name; public $age; public function __construct($name, $age) { $this->name = $name; $this->age = $age; } } $user1 = new User("Alice", 30); $user2 = new User("Alice", 30); $user3 = $user1; // Using == (compares values) if ($user1 == $user2) { echo "user1 is equal to user2\n"; } else { echo "user1 is not equal to user2\n"; } // Using === (compares identity) if ($user1 === $user3) { echo "user1 is identical to user3\n"; } else { echo "user1 is not identical to user3\n"; } ?>
