note 105378 added to function.strftime

Sometimes, you want Jan 1 to be week 1 and weeks to begin on Sunday. Here's a way to use strftime U format character to follow this convention: <?php $month = 5; $year = 2012; echo "Week #'s in May 2012: "; $week_num_correction = strftime('%U', mktime(0,0,0,1,1,$year)) === '00' ? 1 : 0; $week_numbers = range(strftime('%U', mktime(0,0,0,$month,1,$year)) + $week_num_correction, strftime('%U', mktime(0,0,0,$month+1,0,$year)) + $week_num_correction); foreach($week_numbers as $week_number) echo "$week_number "; ?> displays: Week #'s in May 2012: 18 19 20 21 22 ---- Server IP: 69.147.83.197 Probable Submitter: 65.41.147.195 ---- Manual Page -- http://www.php.net/manual/en/function.strftime.php Edit -- https://master.php.net/note/edit/105378 Del: integrated -- https://master.php.net/note/delete/105378/integrated Del: useless -- https://master.php.net/note/delete/105378/useless Del: bad code -- https://master.php.net/note/delete/105378/bad+code Del: spam -- https://master.php.net/note/delete/105378/spam Del: non-english -- https://master.php.net/note/delete/105378/non-english Del: in docs -- https://master.php.net/note/delete/105378/in+docs Del: other reasons-- https://master.php.net/note/delete/105378 Reject -- https://master.php.net/note/reject/105378 Search -- https://master.php.net/manage/user-notes.php
