PHP 8.1: strftime depreceted

[pkristian]

Version: 2.10.6

Bug Description

strftime is deprecated in PHP 8.1 and filter date could produce error.

latte/src/Latte/Runtime/Filters.php

Line 439 in c0cfd1b

: strftime($format, $time->format('U') + 0); // formats according to locales

Steps To Reproduce

{var $str = '2021-12-01 00:00:00'}
({$str|date:'%Y-%m-%d'})

Expected Behavior

not throwing anything

Possible Solution

add @ or replace it all together? :)

The solution is to use the format without % characters, i.e.: Y-m-d.

[MikyWoW]

Format without % using date() function which doesn´t respect locale. Correct solution is implement function IntlDateFormatter::format(). (intl extension required).

Docker:apt-get install -y libicu-dev && docker-php-ext-configure intl && docker-php-ext-install intl

https://unicode-org.github.io/icu/userguide/format_parse/datetime/#date-field-symbol-table

$date = new \DateTime();
$fmt = new \IntlDateFormatter(
            'cs_CZ',
            \IntlDateFormatter::FULL,
            \IntlDateFormatter::FULL,
            'Europe/Prague',
            \IntlDateFormatter::GREGORIAN,
            'EEEE DD. MMMM HH:mm'
);
echo $fmt->format($date);

edit: Correct parameters in IntlDateFormatter

edit2:
Static alternative:

// DateTime need have correct timezone
date_default_timezone_set('Europe/Prague');

$date =  new \DateTime();
echo \IntlDateFormatter::formatObject($date, 'EEEE DD. MMMM HH:mm', 'cs_CZ');
