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.

Syntax

cal_days_in_month( CAL_GREGORIAN, $intMonth, $intYear);

Example:

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.

Syntax

checkdate ($intMonth,$date, $intYear);

Example:
