Private Access
##############

|Packagist| |GitLab| |GitHub| |Bitbucket| |Gitea|

A small simple library to access private properties of the objects.
Actually it's more an example of mad skillz than a useful tool.
No Reflection API calls!

Installation
============

Use composer:

.. code-block:: bash

    composer require arokettu/private-access --dev

Why ``--dev``?
--------------

This library may be used for debugging or with PHP consoles like PsySH.
If you are actually using it in some live system, you're doing something terribly wrong.

Functions
=========

These four simple functions can come in handy as helpers for something like PsySH_

.. note:: All functions also work with protected and public visibilities

Class examples:

.. code-block:: php

    <?php

    class A extends B
    {
        private const SECRET_CONST = '';
        private $secret;
        private static $staticSecret;
        private function doStuff() {}
        private static function doStaticStuff() {}
    }

    class B
    {
        private $secret;
        private function doStuff() {}
    }

    $a = new A();

``get_private_field``
---------------------

Get value of a private field

.. code-block:: php

    <?php

    use function Arokettu\Debug\get_private_field;

    get_private_field($a, 'secret'); // get $a->A::secret value
    get_private_field(A::class, 'staticSecret'); // get A::$staticSecret value
    get_private_field([$a, B::class], 'secret'); // get $a->B::$secret value

``set_private_field``
---------------------

Set value of a private field

.. code-block:: php

    <?php

    use function Arokettu\Debug\set_private_field;

    set_private_field($a, 'secret', 'new secret'); // set new $a->A::secret value
    set_private_field(A::class, 'staticSecret', 'new secret'); // set new A::$staticSecret value
    set_private_field([$a, B::class], 'secret', 'new secret'); // set new $a->B::$secret value

``call_private_method``
-----------------------

Call private method

.. code-block:: php

    <?php

    use function Arokettu\Debug\call_private_method;

    call_private_method($a, 'doStuff', 'whatever'); // call $a->A::doStuff('whatever')
    call_private_method(A::class, 'doStaticStuff', 'whatever'); // call A::doStaticStuff('whatever')
    call_private_method([$a, B::class], 'doStuff', 'whatever'); // call $a->B::doStuff('whatever')

``get_private_const``
---------------------

Get value of a private constant

.. note::
    This function works in all supported PHP versions but is useful only with PHP 7.1+
    where constants can be private or protected

.. code-block:: php

    <?php

    use function Arokettu\Debug\get_private_const;

    get_private_const($a, 'SECRET_CONST');
    // or
    get_private_const(A::class, 'SECRET_CONST');
