How to use iterator_count with ArrayIterator In PHP
Using iterator_count with ArrayIterator involves wrapping the array in an ArrayIterator object, which provides a way to traverse the array. The iterator_count function then counts the elements of this iterator, giving the total number of elements in the array.
Example:
<?php
$array = [1, 2, 3, 4, 5];
$iterator = new ArrayIterator($array);
$count = iterator_count($iterator);
echo "Number of elements: $count";
?>
Output
Number of elements: 5
