Even if documentation says that $cmp_function must be a string, this method works with a Callable also.
Example:
<?php
$iterator->uasort([$this, 'usort']); // 'usort' here is a method in the same class
ArrayIterator::uasort
(PHP 5 >= 5.2.0, PHP 7)
ArrayIterator::uasort — User defined sort
설명
public void ArrayIterator::uasort
( string
$cmp_function
)Sort the entries by values using user defined function.
