非常简单实用的函数,这里就不多废话了,直接奉上代码

代码如下:


/**
     *    日期-获取当月最后一天
     *  @return int
     */
    public function get_lastday() {
        if($this->month==2) {
            $lastday = $this->is_leapyear($this->year) ? 29 : 28;
        } elseif($this->month==4 || $this->month==6 || $this->month==9 || $this->month==11) {
            $lastday = 30;
        } else {
            $lastday = 31;
        }
        return $lastday;
    }
    /**
     *    日期-是否是闰年
     *  @return int
     */
    public function is_leapyear($year) {
        return date('L', $year);
    }

以上就是本代码的全部内容,希望小伙伴们喜欢。
