In PHP, how do I hash objects in vanilla PHP?

In PHP, to hash an object, you can convert it to a JSON string first before applying a hashing function like `md5`, `sha256`, or any other PHP hash function. This will create a unique representation of the object as a hash.

<?php // Create an example object class User { public $name; public $email; public function __construct($name, $email) { $this->name = $name; $this->email = $email; } } // Create a new instance of the User $user = new User("John Doe", "john.doe@example.com"); // Convert the object to a JSON string $jsonString = json_encode($user); // Hash the JSON string $hashedValue = hash('sha256', $jsonString); echo "Hashed Value: " . $hashedValue; ?>
