    The PHP function 'date' is used to display the current date in the specified format as indicated by its arguments as shown in the above example. For more details on date format arguments, click PHP Date Function Tips.

    Syntax

    date('format options');

    Example:

    1.date('y m d'); Output: 05 04 23

    2. date('Y M D'); Output: 2005 Apr Sat

    3.date('Y m d h: s: m'); Output: 2005 04 23 02: 18: 04 (Date and Time)

    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.

    Syntax

    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.

    Syntax

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

    Example:

    1. checkdate (1, 30,2005); Output: (1 means true)

    2. checkdate (2, 30,2005); Output: (null means false)
