Re: Re: Issue with 'W' in the date() function?

I really have to stop replying to myself :) Anyway i think that i have the solution... function timestamp2YearWeek ($time) {

    if (date('z', $time) > 360 && date('W', $time) == 1) {
        return sprintf('%d%02d', date('Y', $time)+1, date('W', $time));
    }else{
        return sprintf('%d%02d', date('Y', $time), date('W', $time));
    }

Ok. Its been a long day and my brain is starting to shut down so... How would i work out which year the 'W' relates to? I have a unix timestamp value and want to end up with the correct 'YW' value. William Bailey wrote:

Hi Mike,

Because week 1 is defined as the first week with four or more days in the new year. Therefore, working backwards, the 29th-31st are also in week 1 in 2004.

Thanks, So now i will just have to check the year and then work out from that what the correct year should be. (i need to get a YW value).
