offsetGet($index) returns the value stored at $index in the cache. Until you've
iterated over the items, the cache is empty and the index will not exist.

<?php
        $cache
= new \CachingIterator(
            new \
ArrayIterator(['a', 'b', 'c', 'd']),
            \
CachingIterator::FULL_CACHE);

       
$shortRange = range(0, 1);

        foreach (
$shortRange as $index) {
           
$cache->next();
        }

        echo
PHP_EOL . 'The cache' . PHP_EOL;
       
var_export($cache->getCache());
        echo
PHP_EOL;

        echo
$cache->offsetGet('1') . PHP_EOL;
        echo
$cache->offsetGet('2') . PHP_EOL;
?>

array (
  0 => 'a',
  1 => 'b',
