What are magic methods?

Magic methods are special methods defined in PHP classes that are triggered by specific events, such as object creation, property access, and method invocation.

Common magic methods in PHP:

  • __construct(): Called when the object is created.
  • __destruct(): Called when the object is destroyed.
  • __get(): Called when accessing a property that does not exist.
  • __set(): Called when setting a non-existent property.
  • __isset(): Called when checking whether the attribute exists.
  • __unset(): Called when clearing attributes.
  • __call(): Called when calling an undefined method.
  • __callStatic(): Called when an undefined static method is called.

Practical case:

Consider a class representing books:

class Book {
    private string $title;
    private int $pages;

    public function __construct(string $title, int $pages) {
        $this->title = $title;
        $this->pages = $pages;
    }
