访问PV、今日访问量、在线人数使用方法：

javascript引用：

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

class minicount
{
    var $dataPth;
    function __construct($dataPth = "minidata/")
    {
        $this->dataPath = $dataPth;
    }
    //解决PHP4不支持__construct问题
    function minicount($dataPth = "minidata/")
    {
        $this->dataPath = $dataPth;
    }
    function diplay($format="a%t%y%m%l%"){
        //echo $format;
        $this->updateCount($this->dataPath.$this->getMainFileName());        //更新总流量

 提示，获取IP方法：

function get_client_ip($type = 0) {
    $type       =  $type ? 1 : 0;
    static $ip  =   NULL;
    if ($ip !== NULL) return $ip[$type];
    if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
        $arr    =   explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
        $pos    =   array_search('unknown',$arr);
        if(false !== $pos) unset($arr[$pos]);
        $ip     =   trim($arr[0]);
    }elseif (isset($_SERVER['HTTP_CLIENT_IP'])) {
        $ip     =   $_SERVER['HTTP_CLIENT_IP'];
    }elseif (isset($_SERVER['REMOTE_ADDR'])) {
        $ip     =   $_SERVER['REMOTE_ADDR'];
    }
    // IP地址合法验证
    $long = sprintf("%u",ip2long($ip));
    $ip   = $long ? array($ip, $long) : array('0.0.0.0', 0);
    return $ip[$type];
}
