PHP页面数据采集程序的主程序

之前我们介绍了采集程序的基类,以及采集插件的具体子类但我们还缺少一个管理程序将所有的插件运行起来,下面是采集程序的主程序考虑了LINUX下可以实现多线程也考虑了对采集时间的配置下面的程序中,我们还用到了两个没有介绍到的文件一个是 require_once('./mail.php'); //用来给商户发邮件 这个是一个邮件类,用来向指定的邮箱发送邮件一个是 $DSN=include("../APP/Config/DSN.php"); 这里定义了数据库服务器的地址,身份验证信息 ,在这里就不公开了.

<?phprequire_once('./Gather_Func.php');  //包括了Mysql类,dump函数require_once('./mail.php');   //用来给商户发邮件$gather=new Gather();$gather->start();return;final class Gather{private $log_file;  //日志文件名private
