my code needs weeks along first , last day in month, code working in months, first , last day of last week becomes combination of first day of next month , last day of current month. start of week sunday.

input date in y-m-d format e.g.(2014-01-05), the day won't matter because converted first day of month anyway.

this output when month january has problem:

2014-01-01 2014-01-04 2014-01-05 2014-01-11 2014-01-12 2014-01-18 2014-01-19 2014-01-25 2014-01-26 2014-01-31 2014-02-02 2014-01-31 // here lies problem 

this output when month february correct:

the functions i'm using:

function getweeks($from) {         $array = array();          $from = date("y-m-d", strtotime($from));          $start_date = date('y-m-01', strtotime($from));         $end_date = date('y-m-t', strtotime($from));         $end_date1 = date('y-m-d', strtotime($end_date." + 6 days"));         $week_array = array();         for($date = $start_date; $date < $end_date1; $date = date('y-m-d', strtotime($date. ' + 7 days')))         {             $getarray = getweekdates($date, $start_date, $end_date);             $week_array[] = $getarray;         }          return $week_array;     }  function getweekdates($date, $start_date, $end_date)     {         $week =  date('w', strtotime($date));         $year =  date('y', strtotime($date));         $from = date("y-m-d", strtotime("{$year}-w{$week}+3"));          if($from < $start_date) $from = $start_date;          $to = date("y-m-d", strtotime("{$year}-w{$week}-6"));         if($to > $end_date) $to = $end_date;          $obj = new stdclass();         $obj->from = $from;         $obj->to   = $to;          return $obj;     } 

i looked @ get work days in week given date not answer question, because uses different implementation. i'd use own implementation.

on getweeks function:

for($date = $start_date; $date < $end_date1; $date = date('y-m-d', strtotime($date. ' + 7 days'))) {     $getarray = getweekdates($date, $start_date, $end_date);     if($getarray) $week_array[] = $getarray; // change } 

on getweekdates function:

$from = date("y-m-d", strtotime("{$year}-w{$week}+3"));  if($from > $end-date) return null; // add if($from < $start_date) $from = $start_date;  $to = date("y-m-d", strtotime("{$year}-w{$week}-6"));
