Feature: #83350 - Add recursive filtering of arrays¶
See Issue #83350
The new method
\TYPO3\CMS\Core\Utility\ArrayUtility::filterRecursive() has been added as an enhancement to the
array_filter() to filter multidimensional arrays.
ArrayUtility::filterRecursive() behaves just like
array_filter() and if no callback is defined,
values are removed if they equal to boolean
false. See converting to boolean.
Arrays can be filtered recursive using the new method.
