 超简单的php图片统计器,这种统计器以前我是用txt文件做的,现在就直接用数据库实现吧.先来看看数据结构吧.

CREATE TABLE `count` (
  `id` int(10) NOT NULL auto_increment,
  `value` varchar(20) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=gb2312 AUTO_INCREMENT=98 ;

好数据准备好了下面我们来看看程序是怎么实现的吧.

//浏览页面时加入一条记录,从而达到访问加1.
 $conn=mysql_connect("localhost","root","root");
 //echo mysql_error();
 mysql_query("set names gb2312");
 mysql_select_db("guest");
 $sql="INSERT INTO `count` ( `id` , `value` ) VALUES ('', '32')";
 $result=mysql_query($sql);
 if ($result) {
  echo "插入成功.";
 }
 mysql_close($conn);
 
 
 //读出记录数据count(*)
 $conn=mysql_connect("localhost","root","root");
 //echo mysql_error();
 mysql_query("set names gb2312");
 mysql_select_db("guest");
 $mysql="select * from `count`";
 
 $result=mysql_query($mysql);
 $row=mysql_num_rows($result);
   for($i=0;$i    {
    $a=substr($row,$i,1);
    $str.= "超简单的php图片统计器";
   }
?>

页面总共有个人浏览

嗯,php代码写得有一点乱喽,但工能还是能实现的吧.
