date('format options');
Example:

2. Number of days in a month
The function 'cal_days_in_month' is used to return the number of days in a month. This function takes three arguments one for calendar name, month value and year value respectively.
cal_days_in_month( CAL_GREGORIAN, $intMonth, $intYear);
Example:
cal_days_in_month ( CAL_GREGORIAN, 1, 2005); Output: 31
3. Check the date format
The function 'checkdate' is used to check whether the date passed as an argument is a valid date or not. The function returns a boolean value of '1' if the date is a valid date and 'Null' if the date is invalid.
checkdate ($intMonth,$date, $intYear);
Example:
1. checkdate (1, 30,2005); Output: (1 means true)
2. checkdate (2, 30,2005); Output: (null means false)
