Can you give examples of magic methods used in classes?

In PHP, magic methods are special methods that start with a double underscore __ and are called automatically in certain situations. Here are some examples:

• __construct() — called when creating an object (constructor).
• __destruct() — called when destroying an object.
• __get($name) — called when attempting to access a non-existent or inaccessible property.
• __set($name, $value) — called when assigning a value to a non-existent or inaccessible property.
• __call($name, $arguments) — called when calling a non-existent or inaccessible method.
• __toString() — called when attempting to convert an object to a string.

Example of usage:

class User {
    private $data = [];

    public function __set($name, $value) {
        $this->data[$name] = $value;
    }

    public function __get($name) {
        return $this->data[$name] ?? null;
    }

    public function __toString() {
        return "User: " . ($this->data['name'] ?? 'unknown');
    }
}

$user = new User();
$user->name = "Ivan";
echo $user; // Will output: User: Ivan
