php怎么判断第一个执行某个文件
php如何判断第一个执行某个文件
php如何判断在00:00之后第一个执行某个文件（test.php）
我想实现一个类似论坛定时清理垃圾帖子的功能：
php定时执行任务的几个方法
找个被频繁调用的网页, 里面加上一个检测代码
论坛上定时清理新帖基本上就是这么实现的, Discuz!是判断在00:00之后,第一个执行者去执行的。
------解决方案--------------------
如果是linux就写一个清理方法放到网站中 ， 在linux下用crontab命令，去定时访问这个网页，就可以了……
------解决方案--------------------
如果是页面触发Discuz 有这功能。
如果是无人自动触发用， 系统的定时任务。
或者参考
