You may refer to (PHP 3 + 4): http://www.acay.com.au/~oscarp/php/index.html > The problem is that any valid date prior to 1 Jan 1970 causes the function > to fail and return the value -1 and that is taken as a valid timestamp. > When it returns -1, it is to be interpreted as bogus date.

Perhaps, an associative array.
