iterator_count() Also Count Arrays
The PHP native function used to accept only iterators. Since PHP 8.1, arrays are also welcomed.
PHP code
<?php
print iterator_count([1,2,3]);
?>
Before
Uncaught TypeError: iterator_count(): Argument #1 ($iterator) must be of type Traversable, array given
After
3
PHP version change
This behavior changed in 8.2.
