php计算工作日

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了php计算工作日相关的知识,希望对你有一定的参考价值。
在做政府项目时经常会遇到要就算工作日的情况,在网上找了一圈就只有一些告诉大家怎么做的没有可以拿来就用的代码(可能是没有找到),所以我就把我写出来的发出来;
我是用thinkphp5写的,原生或其他框架可以直接复制计算节假日类;
首先说下我是怎么做的:
第一步
获取节假日安排,由于考虑到人家接口的稳定性然后又没有找到对应大厂的接口,这个我就自己写了,这个我就不详细写了,后面会贴出对应的代码,直接整合就好了
第二步
我是习惯先写调用的接口,所以在接口中规定要计算的开始时间、天数,返回的格式(最后一天或中间所有的时间)
第三步
调用接口由于到数据库中存的节假日安排的只有一个开始时间没有详细的放假时间,所以先处理详细的放假安排,然后考虑到如果计算天数很大的话可能会出现内存泄漏的问题,所以我就把放假时间和补班时间放在了一个数组中,减少后面的遍历
第四步
生成从指定时间到指定天数的原始数据,如:2019-10-10是开始时间,计算100天工作日的时间,就先生成一百条数据,从10月11日开始明天一条数据存到数组中
第五步
判断原始数据中的时间是否是周六、周日或节假日,是的话就删除对应的值,重新生成,一直处理到没有周六周日和节假日为止,这样就把节假日给就算出来了
第六步
最后就是调用get方法,把计算好的节假日数据请求出来就好了
底下是完整代码,我上传到了github,也可以直接去那里下载,地址:https://github.com/18370800152/php-Calculate-Chinese-workday
