人大多都很向往使用数据库来做自己的计数器,留言本,论坛之类的东西了,本篇将介绍本人自制的计数器程序。
首先建立0~9这10个GIF数字图片,放在img文件夹下,再建立一个PHP文件
——count1.php,程序如下:

$linkptr=mysql_pconnect("localhost","yourname","password");
mysql_select_db("yourname",$linkptr);
mysql_query("update counter
set visited=visited+1 where num=1",$linkptr);
$result=mysql_query("select visited
from counter where num=1",$linkptr);
list($counter)=mysql_fetch_row($result);
$counter=sprintf("%05d",$counter);
for($i=0;$i $tmpstr="";
echo $tmpstr;
}
?>
在主页上适当位置放置代码 include "count1.php" ?>,这样主页上就显示了你的计数器,不过要记住在你的数据库上建立一个TABLE——counter:create table counter(
num int unsigned,
visited int unsigned


);
怎么样,容易吧!中篇我将介绍怎样让你的镜像站也能用上你自己的计数器。
