Previous Comments: ------------------------------------------------------------------------ [2003-01-10 16:50:14] trio@surffi.saunalahti.fi This is a function what php needs for option to date function: function get_a_week( $timestamp ) { //Look the stamp for 1.1.xxxx 00:00:00 for current given stamp $seeking_stamp = mktime( 0, 0, 0, 1, 1, date( "Y", $timestamp ) ); //Week numbers are 1-52 in practically for( $i=1; $i < 53; $i++ ) { //Check if the passed stamp is between monday 00:00:00 and sunday 23:59:59 if( $timestamp => $seeking_stamp and $aika <= (($seeking_stamp+=7*24*3600)-1) ) return $i; //Found a week between 1-52 } //Should never get here return -1; } ------------------------------------------------------------------------ [2003-01-10 16:48:56] iliaa@php.net I cannot replicate this either, marking this as feedback until the user can test with 4.3.0 or later. ------------------------------------------------------------------------ [2003-01-10 16:40:26] trio@surffi.saunalahti.fi 1) I have not that kind of platform to use right know. 2) I am GMT +02:00 timezone. ------------------------------------------------------------------------ [2003-01-10 16:34:37] pollita@php.net Unable to reproduce with script given, output of date("W") is always >= 1 and <= 53. (1) Could you try it with 4.3.0 and see if you get the same results? (2) What timezone are you in? ------------------------------------------------------------------------ [2003-01-10 16:14:17] trio@surffi.saunalahti.fi I found out that date("W", $stamp) can gives a zero as output. <?php $stamp = time(); while( date("W", $stamp ) != 0 ) $stamp+=5000; print date( "d.m.Y H:i W", $stamp ) . " $stamp\n"; ?> Out could be for examble "01.01.2005 00:46 0 1104533193". I check the ISO-8601 standard (version 2000-12-19 ISO/TC 154 N 362) and it says: calendar week is represented by two decimal digits. The first calendar week of a year shall be identified as [01] and subsequent weeks shall be numbered in ascending sequence. Futhermore the date function should have a option for 'normally' week number of the year like most of people does it understand practically: 1.1.xxxx is 1 and so on and finally 31.12.xxxx is 52. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21572&edit=1
