一个比较不错的PHP日历类分享
这篇文章主要介绍了一个比较不错的PHP日历类分享,本文直接给出了实现的类代码和使用方法示例,需要的朋友可以参考下
说到对时期和时间的处理,就一定要介绍一下日历程序的编写。但一提起编写日历,大多数人都会认为日历的作用只是为了在页上显示当前的日期,其实日历在我们的开发中有更重要的作用。例如我们开发一个“记事本”就需要通过日历设定日期,还有一些系统中需要按日期去排任务,也需要日历,等等。本例涉及的日期和时间函数并不是很多,都是前面介绍的内容,主要是通过一个日历类的编写,巩固一下前面介绍过的面向对象的语法知识,以及时间函数应用,最主要的是可以提升初学者的思维逻辑和程序设计能力。将日历类Calendar声明在文件calendar.class.php中,代码如下所示:
year = isset($_GET["year"]) ? $_GET["year"] : date("Y"); //如果用户没有设置月份数,则使用当前系统时间的月份 $this->month = isset($_GET["month"]) ? $_GET["month"] : date("m"); //通过具体的年份和月份,利用date()函数的w参数获取当月第一天对应的是周几 $this->start_weekday = date("w",mktime(0,0,0,$this->month,1,$this->year)); //通过具体的年份和月份,利用date()函数的t参数获取当月的天数 $this->days = date("t",mktime(0,0,0,$this->month,1,$this->year)); } //魔术方法用于打印整个日历 function __toString(){ $out .='
