public function daysBetween($startDate,$endDate) {
    //  Shift the mandatory start and end date that are referenced 
    //  in the function deFinition,to get any optional days
    $holidays = func_get_args();
    array_shift($holidays);
    array_shift($holidays);

$startDate和$endDate是必需参数,而$holidays的所有实例都是可选的……可能没有定义,一个或多个$holiday日期.上面的PHPDocumentor定义给了我

我相信我可以通过修改方法定义来解决这个问题

public function daysBetween($startDate,$endDate,$holidays=NULL) {

但这感觉非常糟糕,我不相信我必须改变我的功能定义才能记录它.有人有任何其他建议吗？
