========================================
Feature: #99048 - Site settings read API
========================================

See :issue:`99048`

Description
===========

Settings for site-specific functionality can now be retrieved by a dedicated
:php:`\TYPO3\CMS\Core\Site\Entity\SiteSettings` object, accessible via a
:php:`\TYPO3\CMS\Core\Site\Entity\Site` object like :php:`$site->getSettings()`.

Settings can be used in custom frontend code to deliver features which might
vary per-site for extensions.


Impact
======

Accessing site settings, which was previously possible via:

:php:`$site->getConfiguration()['settings']['redirects'] ?? []`

in custom PHP code, is now easier via the :php:`SiteSettings` PHP object.

The :php:`SiteSettings` object can be used to access settings either by
the dot notation ("flat", a default value can be given as optional second
argument), e.g.:

..  code-block:: php

    $redirectStatusCode = (int)$siteSettings->get('redirects.httpStatusCode', 307);

or by accessing all options for a certain group:

..  code-block:: php

    $allSettingsRelatedToRedirects = $siteSettings->get('redirects');

or even fetching all settings:

..  code-block:: php

    $allSettings = $siteSettings->all();

In addition, settings can now be accessed in TypoScript via :typoscript:`getData`
with the key :typoscript:`siteSettings`:

..  code-block:: typoscript

    page.10 = TEXT
    page.10.data = siteSettings:redirects.httpStatusCode

.. index:: PHP-API, TypoScript ext:core
