:phpfunction:`iterator_to_array` method, or get the number of items with

:phpfunction:`iterator_count`.

..caution::

When searching through multiple locations passed to the

:method:`Symfony\\Component\\Finder\\Finder::in` method, a separate iterator

is created internally for every location. This means we have multiple result

sets aggregated into one.

Since:phpfunction:`iterator_to_array` uses keys of result sets by default,

when converting to an array, some keys might be duplicated and their values

overwritten. This can be avoided by passing ``false`` as a second parameter

to:phpfunction:`iterator_to_array`.
