[php] get weekdays

[Michael Borchers]

folgende funktion, die ich irgendwo gefunden habe, lief wunderbar, bis zum 
jahreswechsel.
er erkennt schon, dass wir uns in der 2.woche des jahres befinden, aber der 
timestamp wird nicht korrekt f�r heute berechnet.

laut mysql ist der timestamp f�r heute, den 08.01.2007:
1168210800

doch laut funktion: 1167649200

wo ist der fehler?



function get_weekdays($week,$year)
{
 $week_dates = array();

 // Get timestamp of first week of the year
 $first_day = mktime(12,0,0,1,1,$year);
 $first_week = date("W",$first_day);

 if ($first_week > 1) {
    $first_day = strtotime("+1 week",$first_day); // skip to next if year 
does not begin with week 1
 }

 // Get timestamp of the week
 $timestamp = strtotime("+$week week",$first_day);


 // Adjust to Monday of that week
 $what_day = date("w",$timestamp); // I wanted to do "N" but only version 
4.3.9 is installed :-(


 if ($what_day==0) {
    // actually Sunday, last day of the week. FIX;
    $timestamp = strtotime("-6 days",$timestamp);
 } elseif ($what_day > 1) {
    $what_day--;
    $timestamp = strtotime("-$what_day days",$timestamp);
 }

 $week_dates[1] = date("Y-m-d",$timestamp); // Monday
 $week_dates[2] = date("Y-m-d",strtotime("+1 day",$timestamp)); // Tuesday
 $week_dates[3] = date("Y-m-d",strtotime("+2 day",$timestamp)); // Wednesday
 $week_dates[4] = date("Y-m-d",strtotime("+3 day",$timestamp)); // Thursday
 $week_dates[5] = date("Y-m-d",strtotime("+4 day",$timestamp)); // Friday
 #   $week_dates[6] = date("Y-m-d",strtotime("+5 day",$timestamp)); // 
Saturday
 #   $week_dates[7] = date("Y-m-d",strtotime("+6 day",$timestamp)); // 
Sunday
 return($week_dates);
}
