There is probably a more elegant solution than this but you can just use php’s date function:
date(‘t’);
cal_days_in_month.
In order to get no. of days in month you can use either
And if you wish to check if today is the last day of month us can use
strtotime offers many great features so check them out first
Use php’s function: cal_days_in_month
this is to find the days in any month:
And here it is, wrapped up as a function:
Using the modern DateTime object class:

Here’s a one-line function I just wrote to find the numbers of days in a month that doesn’t depend on any other functions.
The reason I made this is because I just found out I forgot to compile PHP with support for calendars, and a class I’m writing for my website’s open source section was broken. So rather than recompiling PHP (which I will get around to tomorrow I guess), I just wrote this function which should work just as well, and will always work without the requirement of PHP’s calendar extension or any other PHP functions for that matter.
I learned the days of the month using the old knuckle & inbetween knuckle method, so that should explain the mod 7 part. 🙂
# PHP Calendar (version 2.3), written by Keith Devens
#remember that mktime will automatically correct if invalid dates are entered
# for instance, mktime(0,0,0,12,32,1997) will be the date for Jan 1, 1998
# this provides a built in «rounding» feature to generate_calendar()
