访问PV、今日访问量、在线人数使用方法：

javascript引用：

<script src="count.php"></script>

 1 class minicount

提示，获取IP方法：

 1 function get_client_ip($type = 0) {
 2     $type       =  $type ? 1 : 0;
 3     static $ip  =   NULL;
 4     if ($ip !== NULL) return $ip[$type];
 5     if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
 6         $arr    =   explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
 7         $pos    =   array_search('unknown',$arr);
 8         if(false !== $pos) unset($arr[$pos]);
 9         $ip     =   trim($arr[0]);
10     }elseif (isset($_SERVER['HTTP_CLIENT_IP'])) {
11         $ip     =   $_SERVER['HTTP_CLIENT_IP'];
12     }elseif (isset($_SERVER['REMOTE_ADDR'])) {
13         $ip     =   $_SERVER['REMOTE_ADDR'];
14     }
15     // IP地址合法验证
16     $long = sprintf("%u",ip2long($ip));
17     $ip   = $long ? array($ip, $long) : array('0.0.0.0', 0);
18     return $ip[$type];
19 }
