定时执行php脚本
对于使用php的童鞋来说,计划任务大家首先想起的是linux下和crontab。但是并非所有人都是使用linux系统,也不是所有人都有独立服务器。这时候如何用php来实现计划任务呢。

所使用的函数是:  ignore_user_abort(),set_time_limit(0),sleep($interval)
此代码只要运行一次后关闭浏览器即可,但是这个方法也有一个问题,就是当重启了apache之后,脚本就被终止了,则需要再次运行。

ignore_user_abort();//关掉浏览器,PHP脚本也可以继续执行.set_time_limit(0);// 通过set_time_limit(0)可以让程序无限制的执行下去$interval=60*30;// 每隔半小时运行do{	//这里是你要执行的代码	sleep($interval);// 等待5分钟}while(true);
