How to get all week start date and end date within a date range in PHP?

Week start = Sunday and week end = Saturday

Input

$start_date='2013-02-01'
$end_date = '2013-02-28'

Output

start date='2013-02-01' End date ='2013-02-02'
start date='2013-02-03' End date ='2013-02-09'
start date='2013-02-10' End date ='2013-02-16'
start date='2013-02-17' End date ='2013-02-23'
start date='2013-02-24' End date ='2013-02-28'

Below code return the week start and end of the date given

 function getWeekDates($date) {     $week =  date('W', strtotime($date));     $year =  date('Y', strtotime($date));     $from = date("Y-m-d", strtotime("{$year}-W{$week}-1")); //Returns the date of monday in week     $to = date("Y-m-d", strtotime("{$year}-W{$week}-7"));   //Returns the date of sunday in week     echo "Start Date-->".$from."End Date -->".$to;//Output : Start Date-->2012-09-03 End Date-->2012-09-09 }

How can I get the result above?

Try this one...

$start_date = date('Y-m-d', strtotime('2013-02-01')); $end_date = date('Y-m-d', strtotime('2013-02-28')); $end_date1 = date('Y-m-d', strtotime('2013-02-28 + 6 days'));  for($date = $start_date; $date <= $end_date1; $date = date('Y-m-d', strtotime($date. ' + 7 days'))) {     echo getWeekDates($date, $start_date, $end_date);     echo "\n"; }  function getWeekDates($date, $start_date, $end_date) {     $week =  date('W', strtotime($date));     $year =  date('Y', strtotime($date));     $from = date("Y-m-d", strtotime("{$year}-W{$week}+1")); //Returns the date of monday in week     if($from < $start_date) $from = $start_date;     $to = date("Y-m-d", strtotime("{$year}-W{$week}-6"));   //Returns the date of sunday in week     if($to > $end_date) $to = $end_date;     echo "Start Date-->".$from."End Date -->".$to;//Output : Start Date-->2012-09-03 End Date-->2012-09-09 }

my answer.

$start_date = '2013-02-01'; $end_date = '2013-02-28';  getWeekDates($start_date, $end_date);  function getWeekDates($date, $enddate) { $week = date('W', strtotime($date)); $year = date('Y', strtotime($date)); $from = date("Y-m-d", strtotime("{$year}-W{$week}-1")); //Returns the date of monday in week $to = date("Y-m-d", strtotime("{$year}-W{$week}-7"));   //Returns the date of sunday in week $Edate = strtotime($enddate); $Sdate = strtotime($to); if ($Edate <= $Sdate) {     echo "<br>Start Date-->" . $from . "End Date -->" . $enddate; //Output : Start Date-->2012-09-03 End Date-->2012-09-09  } else {     echo "<br>Start Date-->" . $from . "End Date -->" . $to; //Output : Start Date-->2012-09-03 End Date-->2012-09-09     $to = date("Y-m-d", strtotime("$to +1days")); //Returns the date of monday in week     getWeekDates($to, $enddate); } }

I hope I get your question right.

What you need to do is call your function with the start date, then add seven days to the start date and call your function again... You have to do this until you reach the end date.

Here is some untested code:

$current_date = strtotime($start_date); $end_date_as_date = strtotime($end_date);  while($current_date < $end_date_as_date){ getWeekDates($current_date); $current_date= strtotime("+7 day", $current_date); }

Hope this helps. If you need any further information leave a comment.
