PHP获取访客ip、系统、浏览器等信息

废话不多说,直接上源码。

1.获取访客操作系统信息

<?php
function GetOs() {
    if (!empty($_SERVER['HTTP_USER_AGENT'])) {
        $OS = $_SERVER['HTTP_USER_AGENT'];
        if (preg_match('/win/i', $OS)) {
            $OS = 'Windows';
        } elseif (preg_match('/mac/i', $OS)) {
            $OS = 'MAC';
        } elseif (preg_match('/linux/i', $OS)) {
            $OS = 'Linux';
        } elseif (preg_match('/unix/i', $OS)) {
            $OS = 'Unix';
        } elseif (preg_match('/bsd/i', $OS)) {
            $OS = 'BSD';
        } else {
            $OS = 'Other';
        }
        return $OS;
    } else {
        return "获取访客操作系统信息失败!";
    }
} ?>

2.获取浏览器信息

<?php
function GetBrowser() {
    if (!empty($_SERVER['HTTP_USER_AGENT'])) {
        $br = $_SERVER['HTTP_USER_AGENT'];
        if (preg_match('/MSIE/i', $br)) {
            $br = 'MSIE';
        } elseif (preg_match('/Firefox/i', $br)) {
            $br = 'Firefox';
        } elseif (preg_match('/Chrome/i', $br)) {
            $br = 'Chrome';
        } elseif (preg_match('/Safari/i', $br)) {
            $br = 'Safari';
        } elseif (preg_match('/Opera/i', $br)) {
            $br = 'Opera';
        } else {
            $br = 'Other';
        }
        return $br;
    } else {
        return "获取浏览器信息失败!";
    }
} ?> 

3.获取浏览器语言

<?php
function GetLang() {
    if (!empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
        $lang = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
        $lang = substr($lang, 0, 5);
        if (preg_match("/zh-cn/i", $lang)) {
            $lang = "简体中文";
        } elseif (preg_match("/zh/i", $lang)) {
            $lang = "繁体中文";
        } else {
            $lang = "English";
        }
        return $lang;
    } else {
        return "获取浏览器语言失败!";
    }
} ?> 

4.获取ip和地址信息

<?php
//获取ip
function getip() {
    if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP") , "unknown")) {
        $ip = getenv("HTTP_CLIENT_IP");
    } else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR") , "unknown")) {
        $ip = getenv("HTTP_X_FORWARDED_FOR");
    } else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR") , "unknown")) {
        $ip = getenv("REMOTE_ADDR");
    } else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown")) {
        $ip = $_SERVER['REMOTE_ADDR'];
    } else {
        $ip = "unknown";
    }
    return $ip;
}
//获取地址
function getLocation($ip = '') {
    empty($ip) && $ip = getip();
    if ($ip == "127.0.0.1") return "本机地址";
    $api = "http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=$ip";   //请求新浪ip地址库
    $json = @file_get_contents($api);
    $arr = json_decode($json, true);
    $country = $arr['country'];
    $province = $arr['province'];
    $city = $arr['city'];
    if ((string)$country == "中国") {
        if ((string)($province) != (string)$city) {
            $_location = $province . $city;
        } else {
            $_location = $country . $city;
        }
    } else {
        $_location = $country;
    }
    return $_location;
} ?>           

i> 使用时直接在需要输出的地方调用函数即可 例如:<?php echo getip();?>
