note 80148 added to function.date

date("W") returns the iso8601 week number, while date("Y") returns the _current_ year. This can lead to odd results. For example today (dec 31, 2007) it returns 1 for the week and of course 2007 for the year. This is not wrong in a strict sense because iso defines this week as the first of 2008 while we still have 2007. So, if you don't have another way to safely retrieve the year according to the iso8061 week-date - strftime("%G") doesn't work on some systems -, you should be careful when working with date("W"). For most cases strftime("%W") should be a safe replacement. ---- Server IP: 217.13.201.10 Probable Submitter: 80.171.71.190 ---- Manual Page -- http://www.php.net/manual/en/function.date.php Edit -- https://master.php.net/note/edit/80148 Del: integrated -- https://master.php.net/note/delete/80148/integrated Del: useless -- https://master.php.net/note/delete/80148/useless Del: bad code -- https://master.php.net/note/delete/80148/bad+code Del: spam -- https://master.php.net/note/delete/80148/spam Del: non-english -- https://master.php.net/note/delete/80148/non-english Del: in docs -- https://master.php.net/note/delete/80148/in+docs Del: other reasons-- https://master.php.net/note/delete/80148 Reject -- https://master.php.net/note/reject/80148 Search -- https://master.php.net/manage/user-notes.php
