示例1: nextDay

* local year
* @param string $format the string indicating how to format the output
*
* @return string the date in the desired format

}示例2: subtractSpan
/**
* Subtracts a time span from the date
*
* N.B. it is impossible for this function to count leap seconds,
* because the result would be dependent on which order the consituent
* parts of the span are subtracted from the date. Therefore, leap
* seconds are ignored by this function. If you want to count leap
* seconds, use 'subtractSeconds()'.
*
* @param object $span the time span to subtract
*
* @return void
* @access public
