Find how many days to next month

[datona]

I know that for most guru's, you must think that this is an easy one BUT as a newbe, I just can't figure it out.
This is suppose to be a payment page. If a client wants to signup for a service and it is the 20th of the month, it will take the service price of $15 and prorate it for the remaining days in the month.
If the days remaining is less then 10, then it will ALSO add in the following month.

Thanks alot peoples😉

Haven't tested this yet, but it should work...

$today = mktime(); //get timestamp of today

$month = date("m"); //current numberic month
$year = date("Y"); //current numeric year
$nextMonth = ($month + 1); //numeric next month

// calculate if next month is January
//and add year, set month to 1
if($nextMonth == 13) { 
	$year = ($year+1);
	$nextMonth = 1;
}

// get timestamp for the first of next month
$var = mktime(0,0,0,$nextMonth,1,$year);

//get difference in timestamp, 
//divide by days(86400 seconds)
//and format it to a whole number
$diff = number_format(($var-$today)/86400);

echo $diff." days until next month";

WOW LordShryku!

That works like a charm.
Thank you SO much 😃

That could be simplified as such:

<?PHP
$date = date("j"); #gets current day in month
$month_len = date("t"); #gets number of days in current month
echo $month_len - $date." days until next month";
?>
