用Php实现链结人气统计_PHP

Jun 01, 2016 pm 12:29 PM
i lines url accomplish document statistics count

首先要说明:这个不是主页计数器,虽然原理和它相同。
一:准备一个计数文件,存放链结的url和访问次数,格式如下
id|url|count
id是用来查找的索引号,url为实际文件的地址,count为次数
实例数据:
doc01|docs/doc01.html|10
doc02|docs/doc02.html|10
二:准备count.php文件,代码如下:
//功能:传入参数id,在计数文件查找相应的url,增加计数,并返回实际的链接
$countfile="count.txt";
$lines=file($countfile);//将计数文件内容读到数组$lines中
for($i=0;$i {
list($sid, $url, $count)=explode("|", $lines[$i]);
//分解字符串为$id,$url,$count
if($sid==$id) //查找指定id
{
$count =1; //增加计数
$lines[$i]=$sid . "|" . $url . "|" . "$count" . "\n";//重新生成计数字符串
break;

}
}
//写入计数信息
$fp=fopen($countfile, "w");
for($i=0;$i fputs($fp, $lines[$i]);
fclose($fp);
Header("Location: $url");
?>
注:这个是phpuser.com上的不完全版本,我加了一些改动,现在应该是能用的。

三:主页中超链结的调用方式应该改为:
doc01
程序功能是:
首先将计数文件内容读到数组中
再从数组中查找指定id号,如找到则$url为相应的文件的真正链接,再将计数加1,
重新生成计数信息
将计数信息写入文件中
返回链接

四:访问人数引用就是下面这几句,写个function也可以,我偷了把懒,
谁写好了给我一个 :)
$countfile="count.txt";
$lines=file($countfile);
list($sid,$url,$count) = explode("|",$lines[0]);//$lines[0]对应count.txt中
//第一条记录
echo $count;
?>
