【YourPHPv2.1正式版（v2.2_Released）完整代码+使用手册+安装截图】个人比较喜欢YourPHP后台风格，简单大方。
只是，YourPHPv3.0后将核心代码加密了，而官网又不能正常访问，导致YourPHPv3.0安装后，首页显示乱码，完全用不了~想用用不了，急死人！浪费了大把大把时间，很是无语！……功夫不负有心人，问题得到解决，代码是YourPHPv2.1正式版（v2.2_Released）官网下载，本人亲测可用同时打包程序代码+使用手册+安装截图供朋友们下载研究2018.4.24

这个只是方便生成授权，只要填入各个程序的licensehash就能生成不通的应用程序的授权了，licensehash的外置，比原版的生成器方便使用，只要一个生成器就能给你所有的加密程序提供授权的生成了。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
