复制代码 代码如下:
<?php

$counter=1;
if(file_exists("mycounter.txt")){
$fp=fopen("mycounter.txt","r");
$counter=fgets($fp,9);
$counter++;
fclose($fp);
}
$fp=fopen("mycounter.txt","w");
fputs($fp,$counter);
fclose($fp);
echo "<h1>您是第".$counter."次访问本页面！<h1>";
?>

复制代码 代码如下:
<?php
//下面这个为使用基于数据库的简单计数器，未添加其他防止一人重复刷新的方法。仅供参考。。
$conn=mysql_connect("localhost","root","abc");
$result=mysql_query("use db_counter");
$re=mysql_query("select * from tb_counter");
$result=mysql_fetch_row($re);
$counter=$result[0];
echo "您是第{$counter}位访问者！";
$counter+=1;echo "<hr>{$counter}";
mysql_query("update tb_counter set counter=$counter");
mysql_close($conn);
?>
