In PHP, how do I compare objects for beginners?

In PHP, comparing objects can be done using either the equality operator (`==`) or the identity operator (`===`). The equality operator compares the values of the properties of the objects, while the identity operator checks if both objects are actually the same instance.

Example of Comparing Objects in PHP

Here’s a simple example to illustrate how you can compare two objects:

<?php class Person { public $name; public $age; public function __construct($name, $age) { $this->name = $name; $this->age = $age; } } $person1 = new Person("John", 30); $person2 = new Person("John", 30); $person3 = $person1; // Using the equality operator if ($person1 == $person2) { echo "person1 is equal to person2 based on their properties.\n"; } // Using the identity operator if ($person1 === $person3) { echo "person1 is identical to person3 (same instance).\n"; } ?>
