help using date() and mktime()

[Anon]

I am having problems rendering the correct first day for every month that does not have 31 days in it. Does anyone know what the actual value of date(t) returns; It says in the docs, it returns the values 28 thru 31. I have my script checking for leap years. Basically I am able to render the correct first day of the month in my calendar for Jan,March,May,July,August,October and December, all months with 31 days. Any suggestions, I would be most grateful. Thanks, Jules

Are you feeding date() a valid timestamp? date() can automatically deal with leapyears, the "L" format string returns a boolean for leapyear.

also, you can use checkdate() to see if a date is valid, like: checkdate( 1, 18, 2002) will return TRUE while checkdate( 2, 29, 2003) would return FALSE.
