mcal_days_in_month

Name

mcal_days_in_month — Returns the number of days in the given month, needs to know if the year is a leap year or not

Synopsis

int mcal_days_in_month(month, leap); int month: The month, 1 - 12, 1 being January, 12 being December bool leap: Whether or not it is a leap year

Returns

The number of days in the given month, taking into account whether or not it is a leap year, or -1 on an error

Description

mcal_days_in_month() tells you how many days there are in a given month. This is not especially useful for checking how many days there are in February, since you already need to know whether or not it is a leap year. However, it is extremely useful if you want to avoid hardcoding month-specific logic into your application.

Version

PHP 3 since 3.0.13, PHP 4 since 4.0b4

Example

Example 702. Determining how many days there are in each month of a year

$year = 2002;
$isLeap = mcal_is_leap_year($year);

echo "There are: ";
for ($month = MCAL_JANUARY; $month <= MCAL_DECEMBER; $month++) {
    if ($month == MCAL_DECEMBER) {
        echo " and ";
    } elseif  ($month != MCAL_JANUARY) {
        echo ", ";
    }
    echo mcal_days_in_month($month, $isLeap);
}
echo " days in the months of " . $year;
