PHP基于cookie与session统计网站访问量并输出显示的方法,cookiesession

本文实例讲述了PHP基于cookie与session统计网站访问量并输出显示的方法。分享给大家供大家参考,具体如下:

<&#63;php
$f_open = fopen("count.txt","r+"); //打开指定的文件
$count = fgets($f_open); //读取文件中的数据
if(empty($_COOKIE['cookie_name'])){ //判断COOKIE的是否存在
 setcookie("cookie_name",value,time()+1800); //如果不存在,则创建COOKIE
 $count = $count + 1; //将变量$count的值加1
 rewind($f_open); //打开指定的文件
 fwrite($f_open,$count); //向文件中写入新的数据
 fclose($f_open); //关闭文件
}
&#63;>

Copy after login
<&#63;php session_start(); include("conn/conn.php");
 $data1=date("Y-m-d"); //获取当前访问时间
 $data2=substr(date("Y-m-d"),0,7);
 $ip=getenv('REMOTE_ADDR');
 if($_SESSION[temp]=="" || $_SESSION[temp]==NULL){ //判断$_SESSION[temp]==""的值是否为空,其中的temp为自定义的变量
 //使用数据库存储数据
 $select=mysql_query("select * from tb_count10 where data1='$data1' and ip='$ip'");
 if(mysql_num_rows($select)>0){
  $query1="update tb_count10 set counts=counts+1 where data1='$data1' and ip='$ip'";
  $result1=mysql_query($query1);
 }else{
 $query="insert into tb_count10(counts,data1,data2,ip)values('1','$data1','$data2','$ip')";
    $result=mysql_query($query);
 }
 $_SESSION[temp]=1; //登录以后,$_SESSION[temp]的值不为空,给$_SESSION[temp]赋一个值1
 }
&#63;>

Copy after login
<&#63;php
  //以图形的形式输出数据库中的记录数
  $query="select sum(counts) as counts from tb_count04 ";//查询数据库中总的访问量
  $result=mysql_query($query);
  $visitor=mysql_result($result,0,'counts');
  echo "----------";
  echo "<strong>网站的访问量: </strong>"; //以图形的方式显示访问次数
  //对补位数字0的处理
  $len=strlen($visitor); //获取字符串的长度
  $str=str_repeat("0",6-$len); //获取6-$len个数字0
  for($i=0;$i<strlen($str);$i++){ //获取变量$str的字符串长度
   $result=$str[$i];
   $result='<img  src=images/0.gif alt="PHP基于cookie与session统计网站访问量并输出显示的方法,cookiesession_PHP教程" >';
   echo $result; //循环输出$result的结果
  }
  //对数据库中数据的处理
  for($i=0;$i<strlen($visitor);$i++){ //获取字符串的长度
   $result=$visitor[$i];
   switch($result){
   //如果值为"0",则输出0.gif图片
   case "0"; $ret[$i]="0.gif";break;
   case "1"; $ret[$i]="1.gif";break;
   case "2"; $ret[$i]="2.gif";break;
   case "3"; $ret[$i]="3.gif";break;
   case "4"; $ret[$i]="4.gif";break;
   case "5"; $ret[$i]="5.gif";break;
   case "6"; $ret[$i]="6.gif";break;
   case "7"; $ret[$i]="7.gif";break;
   case "8"; $ret[$i]="8.gif";break;
   case "9"; $ret[$i]="9.gif";break;
   }
   echo "<img  src=images/".$ret[$i].". alt="PHP基于cookie与session统计网站访问量并输出显示的方法,cookiesession_PHP教程" >"; //输出访问次数
}
&#63;>
