[原创]最简单的文本计数器--(好象也不简单,呵呵夸大了~)_PHP
计数器
$file="count.dat";if(@file_exists($file)){
$fp=@file($file);
$num=$fp[0];
$f=fopen($file,"w+");
$number=$num+1;
fputs($f,$number);
}else{
$f=fopen($file,"a+");
fputs($fp,"0");
}
@fclose($f);
?>
您好=$_SERVER["REMOTE_ADDR"]?>,您是本站的第[=$number?>]位客人
封装为
class Counter{
function addnumber(){
//多用户 function addnumber($user){ //提示:您可以使用ID来进行多用户(多页面)计数例如:$c=new Counter;$c->addnumber($id);
$file="count.dat";
//多用户(页面) $file=$user.".dat";
if(@file_exists($file)){
$fp=@file($file);
$num=$fp[0];
$f=fopen($file,"w+");
$number=$num+1;
fputs($f,$number);
}else{
$f=fopen($file,"a+");
fputs($fp,"0");
}
@fclose($f);
print("您好$_SERVER["REMOTE_ADDR"],您是本站的第[$number]位客人");
}
}
调用
eg.php
$co=new Conter;
$co->addnumber(); //单用户计数
$co->addnumber($id); //多用户(页面)计数,这里的ID可以为您数据库内符合记录的用户ID,也可以为你剥除了目录的PHP_SELF,呵呵,单独放个counter目录,里面每个页面(用户)都有他自己同样名称的.dat文件来记录他的
页面的访问量~,简单的也可以做不简单的事情哦~
