strftime() replacement function for PHP 8.1
<?php
namespace PHP81_BC;
/**
* Locale-formatted strftime using IntlDateFormatter (PHP 8.1 compatible)
* This provides a cross-platform alternative to strftime() for when it will be removed from PHP.
* Note that output can be slightly different between libc sprintf and this function as it is using ICU.
*
* Usage:
* use function \PHP81_BC\strftime;
