HomeBackend DevelopmentPHP Tutorial打造计数器DIY三步曲(中)

本篇将介绍在自己的镜像站上也能放上自己的计数器。
  我以假设您有多个镜像站为例,首先在数据表中插入几个新的数据num、visited,这在你的镜像站上将用的着,只要将上篇中的count1.php改一下即可.
  先建立一个文件夹count,里面放上您要用的文件count2.php,count3.php……,举个例子,如count2的源码,将count1.php改成:


$linkptr=MySQL_pconnect("localhost","yourname","passWord");

mysql_select_db("yourname",$linkptr);
mysql_query("update counter
  set visited=visited+1 where num=2",$linkptr);
$result=mysql_query("select visited
  from counter where num=2",$linkptr);
list($counter)=mysql_fetch_row($result);
$counter=sPRintf("%05d",$counter);

for($i=0;$i   $tmpstr="打造计数器DIY三步曲(中)";
  echo $tmpstr;
  }
?>
  注意:"打造计数器DIY三步曲(中)   做完这一步,我们再建立一个文件夹show,里面放上对应的文件show2.php,
show3.php……,以show2.php为例,源码写为:

document.write(" include "../count/count2.php" ?>");

  注意: include "../count/count2.php" ?>别忘了count前打上两点,这才是完整的路径!
  最后,在您的镜像站上适当的位置放置代码:

  http://cnfree.oso.com.cn 是我在OSO上的空间,您可以换成您自己的!
  好了,一切OK!看看您的镜像站主页计数器是否也显示出来了?下篇我只是介绍向您的站点会员提供免费计数器的一些构思,基本上就是本篇内容的一些拓展.
