<?php
    protected static function applyRecursively(array $data, Closure $callback)
    {
        /* Initialize the RecursiveArrayIterator for the provided data */
        $arrayIterator = new RecursiveArrayIterator($data);

        /* Configure the Iterator for the RecursiveIterator */
        $recursiveIterator = new RecursiveIteratorIterator(
            $arrayIterator,
            RecursiveIteratorIterator::SELF_FIRST
        );

        /* Traverse the provided data */
        foreach ($recursiveIterator as $key => $value) {
            /* Get the current sub iterator with Type hinting */
            /** @var RecursiveArrayIterator */
            $subIterator = $recursiveIterator->getSubIterator();

            /* Process the element with the provided closure */
            $callback($value, $key, $subIterator);

            /* Update (possibly) changed value */
            $subIterator->offsetSet($key, $value);

The method offsetSet() does not exist on RecursiveIterator. It seems like you code against a sub-type of RecursiveIterator such as Phar or RecursiveCachingIterator or SimpleXMLElement or RecursiveArrayIterator or SimpleXMLIterator or Phar.

        }

        /* Return the processed data */
        return $arrayIterator->getArrayCopy();
    }
