cal_info: Getting information about type of calendar used

Inspect supported calendar information

cal_info() returns names, month data and related information for a selected calendar.

$info = cal_info(CAL_GREGORIAN);
echo $info['calname'];

This function returns all information available on particular calendar type. Here is the syntax

cal_info($calendar);

Here cal_int is an integer to identify the type of calendar required. Here are the values


	0 : CAL_GREGORIAN ( Gregorian Calendar )

	1 : CAL_JULIAN  ( Julian Calendar )

	2 : CAL_JEWISH  ( Jewish Calendar )

	3 : CAL_FRENCH  ( French Revolutionary Calendar )

Here is an example of displaying information about the Julian calendar. Use the named constant instead of the numeric calendar ID.

$a = cal_info(CAL_JULIAN);
foreach($a as $key => $val) {
echo "$key -> $val <br>"; 
	foreach($val as $key1 => $val1) {
		echo "$key1 -> $val1 <br>"; 
	}
}

The Output is here

months -> Array 
1 -> January 
2 -> February
3 -> March 
4 -> April 
5 -> May 
6 -> June
7 -> July
8 -> August

Inspect every supported calendar

Calling cal_info() without a calendar argument returns information for all supported calendars. Use nested foreach loops; the old each() function was removed from PHP.

$calendars = cal_info();
foreach ($calendars as $calendarId => $calendar) {
    echo $calendar['calname'] . "<br>";
    foreach ($calendar['months'] as $number => $month) {
        echo $number . ' - ' . $month . "<br>";
    }
}
