Check valid date

[yklxmas]

Hello all,I'm trying to validate a given date.I tried this function$day = 02;$month = 02;$year = 2007;$DateValidation = mcal_date_valid($day, $month, $year);echo $DateValidation;but I was thrown an error saying undefine function. Doesn't this function exist in php5 anymore? If not, what would you advice to use?Many thanks in advance

Hi!Try this function (I don't know of any predfined functions that can do that...):

function ValiDate( $date, $month = 0, $year = 0){	// If $date is a string	if (is_string( $date )) {		// Let's use preg_match fot date-strings (This will check for date format as day-month-full year)		//  It's not the best reg.exp... :?)		return preg_match( '/^[0-3][0-9]-[01][0-9]-[12][09][0-9][0-9]$/', $date );	} else {		// Get the length of the month		switch( $month ) {			case 1: case 3: case 5: case 7: case 8: case 10: case 12: {				$month_length = 31;				break;			 }			case 2: {				// Don't check for "leap years" right now...				$month_length = 29;				break;			 }			default: {				$month_length = 30;			 }		};		// Check date (integers...)		if (($date >= 1) && ($date <= $month_length) &&			($month >= 1) && ($month <= 12) &&			($year >= 1931) && ($year <= 2030))				return true;		else				return false;	}}

Usage :

$valid = valiDate( $day, $month, $year );or$valid = valiDate( '02-03-2004' );

Hope that helped some.. :?)Good Luck and Don't Panic!
