Question

Hii i am working on portal which requires calendar from custom dates like from 14 Jul to 14 Aug.I have made a demo which starts properly i.e.if 14th july starts from Thursday but not ending at sunday which is on 14 aug. Take a look what i have done
function getCalender($year = '',$month = '')
{
$startDate = "2016-07-03";
$endDate = "2016-07-31";
$dateYear = ($year != '')?$year:date("Y");
$dateMonth = ($month != '')?$month:date("m");
$date = $dateYear.'-'.$dateMonth.'-01';
$currentMonthFirstDay = date("N",strtotime($date));
$startDateFrom = date("N",strtotime($startDate));
$endDateFrom = date("N",strtotime($endDate));
$timestamp = strtotime($startDate);
$dayCount = date("d", $timestamp);
$timestamp1 = strtotime($endDate);
$dayCountend = date("d", $timestamp1);
$totalDaysOfMonth = cal_days_in_month(CAL_GREGORIAN,$dateMonth,$dateYear);
$totalDaysOfMonthDisplay = ($currentMonthFirstDay == 7)?($totalDaysOfMonth):($totalDaysOfMonth + $currentMonthFirstDay);
//$boxDisplay = ($totalDaysOfMonthDisplay <= 35)?35:42;
//$boxDisplay = 29

Answer 1

I tried for your code and i found one logic i took start date and end date from the user and made the array of the dates which are present between two.
Then calendar should start from for ex. 3 Jul 2016 the day is Sunday for that i inserted - upto first date. Check below what i have done
function getCalender($year = '',$month = '',$startDate = '',$endDate = '')
{
$finalArray = array();
$startDate = "2016-07-03";
$endDate = "2016-08-31";
$date1 = createDateRangeArray('2016-07-03 ','2016-08-31');
//$date = $dateYear.'-'.$dateMonth.'-01';
$startDateFrom = date("N",strtotime($startDate));
$endDateFrom = date("N",strtotime($endDate));
//Take the day from the date
$timestamp = strtotime($startDate);
$dayCount = date("d", $timestamp);
//Take the month from the date
$timestampend = strtotime($endDate);
$dayCountend = date("d", $timestampend);
//Take the month from the date
$timestampmonth = strtotime($startDate);
$monthstart = date("m", $timestampmonth);
//Take the month from the date
$timestampmonthend = strtotime($endDate);
$monthend = date("m", $timestampmonthend);
//Take the year from the start date
$yearstart = strtotime($startDate);
$yearofStart = date("y", $yearstart);
//Take the year from the end date
$yearend = strtotime($endDate);
$yearofEnd = date("y", $yearend);
//cal difference between start date and month
$differenceStartDate = $dayCount - 1;
//cal difference between end date and month
$totalDaysOfMonthEnd = cal_days_in_month(CAL_GREGORIAN,$monthend,$yearofEnd);
$totalDaysOfMonthStart = cal_days_in_month(CAL_GREGORIAN,$monthstart,$yearofEnd);
if($monthstart == $monthend)
{
echo "Show one month calendar";
}
else
{
$diffmonth = $monthend-$monthstart;
}
$differenceStartDate = $dayCountend - $totalDaysOfMonth;
for($i=1;$i<$startDateFrom;$i++)
{
$date[] = '-';
}
array_push($date,$date1);
for($j=0;$j<count($date);$j++)
{
if(strlen($date[$j])==1)
{
array_push($finalArray,$date[$j]);
}
else
{
for($k=0;$k<count($date[$j]);$k++)
{
array_push($finalArray,$date[$j][$k]);
}
}
}
print_r($finalArray);
$timestamp1 = strtotime($endDate);
$dayCountend = date("d", $timestamp1);
$now = strtotime($startDate);
$your_date = strtotime($endDate);
$datediff = $your_date - $now;
$diff= floor($datediff/(60*60*24));
$totalDaysOfMonth = cal_days_in_month(CAL_GREGORIAN,$dateMonth,$dateYear);
$totalDaysOfMonthDisplay = ($currentMonthFirstDay == 7)?($totalDaysOfMonth):($totalDaysOfMonth + $currentMonthFirstDay);
//$boxDisplay = ($totalDaysOfMonthDisplay <= 35)?35:42;
$boxDisplay = $diff;
?>

// that in the main script
$aryRange=array();
$iDateFrom=mktime(1,0,0,substr($strDateFrom,5,2), substr($strDateFrom,8,2),substr($strDateFrom,0,4));
$iDateTo=mktime(1,0,0,substr($strDateTo,5,2), substr($strDateTo,8,2),substr($strDateTo,0,4));
if ($iDateTo>=$iDateFrom)

array_push($aryRange,date('Y-m-d',$iDateFrom)); // first entry

array_push($aryRange,date('Y-m-d',$iDateFrom));

}
?>
Take a look at a code and you will understand that easily

Answer 2

The answer given by #BeDeveloper is fine.I made something like below which automatically disable all the other dates for ex.if date 3 it will disable 1 and 2
<style>
/* calendar */
h1 { font-family: calibri; font-size: 20px; color: #6d6d6d}
table.calendar { border-left:1px solid #999; }
tr.calendar-row { }
td.calendar-day { min-height:80px; font-size:11px; position:relative; } * html div.calendar-day { height:80px; }
td.calendar-day:hover { background:#eceff5; }
td.calendar-day-np { background:#eee; min-height:80px; } * html div.calendar-day-np { height:80px; }
