    List out the predefined classes in PHP?

    Directory

    stdClass

    __PHP_Incomplete_Class

    exception

    php_user_filter

    Best way to check your reserved classes is,
    var_dump (get_declared_classes ());

    Standard Defined Classes

    These classes are defined in the standard set of functions included in the PHP build.

    Directory
    The class from which dir is instantiated.
    stdClass
    Created by typecasting to object.
    __PHP_Incomplete_Class
    Possibly created by unserialize().

    Predefined classes as of PHP 5

    These additional predefined classes were introduced in PHP 5.0.0.

    exception
    php_user_filter

    Closure

    The predefined final class Closure was introduced in PHP 5.3.0. It is used for internal implementation of anonymous functions.

    The class has a constructor forbidding the manual creation of the object (issues E_RECOVERABLE_ERROR) and the __invoke method with the calling magic.
