cal_info(): Information about calendar used

This function returns all information available on particular calendar type. Here is the syntax
cal_info(cal_int);
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 all information about Julian Calendar

$a=cal_info(1);
while (list ($key, $val) = each ($a)) {
echo "$key -> $val <br>";
while (list ($key1, $val1) = each ($val)) {
echo "$key1 -> $val1 <br>";
}
}

This is a two dimensional array so we have used two while loops to display all information. If we don't give any calendar number then by default all calendars will be returned. Here it will be a three dimensional array. Here is a sample code.
<table><tr><td valign=top>
$a=cal_info();
while (list ($key, $val) = each ($a)) {
echo "$key -> $val <br>";
while (list ($key1, $val1) = each ($val)) {
echo "$key1 -> $val1 <br>";
while (list ($key2, $val2) = each ($val1)) {
echo "$key2 -> $val2 <br>";
}
}
echo "</td><td valign=top>";
}
echo "</td><td valign=top>";
