Introduction

In this article I explain the “cal_days_in_month()” function in PHP. This function returns the number of the days in a month for the given year and calendar.

Use of this function

You can easily determine how many days are in the month and you can determine the days of any month.

Syntax

Cal_days_in_month(calendar , month , year);

Parameter	Description
Calendar	Calendar to use for calculation.
Month	Month in select calendar.
Year	Year in select calendar.

Returns the length in days of the selected month in the given calendar.

Example

$cal = cal_days_in_month(CAL_GREGORIAN, 5, 2013);
echo “There was $cal days in may 2013”;
?>

Output

Example

$cal = cal_days_in_month(CAL_GREGORIAN, 11, 2011);
echo “There was $cal days in november 2011”;
?>

Output

Next I will explain how many days are in the month without using any calendar and determine the days used by the date function. But you will use these techniques to determine the current days of the month.

Example

“-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
“http://www.w3.org/1999/xhtml”>

How many days in the month
date_default_timezone_set(‘america/new_york’);
$mnth_name = date(‘F’);
echo ‘
The month is ‘
. $mnth_name .”;
echo ‘
Therefore ‘
;
$mnth = date(‘n’);
if($mnth==1)
{
echo ‘days is 31’;
}
if($mnth==2)
{
echo ‘days is 28 unless it is a leap year’;
}
if($mnth==3)
{
echo ‘days is 30’;
}
if($mnth==4)
{
echo ‘days is 30’;
}
if($mnth==5)
{
echo ‘days is 31’;
}
if($mnth==6)
{
echo ‘days is 29’;
}
if($mnth==7)
{
echo ‘days is 31’;
}
if($mnth==8)
{
echo ‘days is 31’;
}
if($mnth==9)
{
echo ‘days is 30’;
}
if($mnth==10)
{
echo ‘days is 31’;
}
if($mnth==11)
{
echo ‘days is 30’;
}
if($mnth==12)
{
echo ‘days is 31’;
}
?>
