Doc #79858 [NEW]: IntlDateTimeFormatter spec does not match PHP

From: m dot smeets at performation dot com Operating system: Linux PHP version: 7.3.20 Package: Date/time related Bug Type: Documentation Problem Bug description:IntlDateTimeFormatter spec does not match PHP Description: ------------ --- From manual page: https://php.net/class.intldateformatter --- According to https://www.php.net/manual/en/function.date.php 'Y' is "A full numeric representation of a year, 4 digits" and 'o' is "ISO-8601 week-numbering year. This has the same value as Y, except that if the ISO week number (W) belongs to the previous or next year, that year is used instead. (added in PHP 5.1.0)" But in IntlDateFormatter "Y" is "Week of Year", shown in http://userguide.icu-project.org/formatparse/datetime. This means that the following format will be interpreted differently Test script: --------------- date = 2018-12-31 format = d-m-Y PHP date_format "31-12-2019" IntlDate format "31-12-2020" Expected result: ---------------- Expected result is the same, but I expect a warning on the PHP IntlDateFormatter page: https://www.php.net/manual/en/class.intldateformatter.php -- Edit bug report at https://bugs.php.net/bug.php?id=79858&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79858&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79858&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79858&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79858&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79858&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79858&r=support Expected behavior: https://bugs.php.net/fix.php?id=79858&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79858&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79858&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79858&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79858&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79858&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79858&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79858&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79858&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79858&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79858&r=mysqlcfg
