Posted 2021-01-06

1.获取访客操作系统信息

1.  
   <?php
2.  
   function GetOs() {
3.  
   if (!empty($_SERVER[‘HTTP_USER_AGENT‘])) {
4.  
   $OS = $_SERVER[‘HTTP_USER_AGENT‘];
5.  
   if (preg_match(‘/win/i‘, $OS)) {
6.  
   $OS = ‘Windows‘;
7.  
   } elseif (preg_match(‘/mac/i‘, $OS)) {
8.  
   $OS = ‘MAC‘;
9.  
   } elseif (preg_match(‘/linux/i‘, $OS)) {
10.  
    $OS = ‘Linux‘;
11.  
    } elseif (preg_match(‘/unix/i‘, $OS)) {
12.  
    $OS = ‘Unix‘;
13.  
    } elseif (preg_match(‘/bsd/i‘, $OS)) {
14.  
    $OS = ‘BSD‘;
15.  
    } else {
16.  
    $OS = ‘Other‘;
17.  
    }
18.  
    return $OS;
19.  
    } else {
20.  
    return "获取访客操作系统信息失败！";
21.  
    }
22.  
    } ?>

2.获取浏览器信息

1.  
   <?php
2.  
   function GetBrowser() {
3.  
   if (!empty($_SERVER[‘HTTP_USER_AGENT‘])) {
4.  
   $br = $_SERVER[‘HTTP_USER_AGENT‘];
5.  
   if (preg_match(‘/MSIE/i‘, $br)) {
6.  
   $br = ‘MSIE‘;
7.  
   } elseif (preg_match(‘/Firefox/i‘, $br)) {
8.  
   $br = ‘Firefox‘;
9.  
   } elseif (preg_match(‘/Chrome/i‘, $br)) {
10.  
    $br = ‘Chrome‘;
11.  
    } elseif (preg_match(‘/Safari/i‘, $br)) {
12.  
    $br = ‘Safari‘;
13.  
    } elseif (preg_match(‘/Opera/i‘, $br)) {
14.  
    $br = ‘Opera‘;
15.  
    } else {
16.  
    $br = ‘Other‘;
17.  
    }
18.  
    return $br;
19.  
    } else {
20.  
    return "获取浏览器信息失败！";
21.  
    }
22.  
    } ?>

 

3.获取浏览器语言

1.  
   <?php
2.  
   function GetLang() {
3.  
   if (!empty($_SERVER[‘HTTP_ACCEPT_LANGUAGE‘])) {
4.  
   $lang = $_SERVER[‘HTTP_ACCEPT_LANGUAGE‘];
5.  
   $lang = substr($lang, 0, 5);
6.  
   if (preg_match("/zh-cn/i", $lang)) {
7.  
   $lang = "简体中文";
8.  
   } elseif (preg_match("/zh/i", $lang)) {
9.  
   $lang = "繁体中文";
10.  
    } else {
11.  
    $lang = "English";
12.  
    }
13.  
    return $lang;
14.  
    } else {
15.  
    return "获取浏览器语言失败！";
16.  
    }
17.  
    } ?>

4.获取ip和地址信息

ip地址信息由新浪ip库提供

1.  
   <?php
2.  
   //获取ip
3.  
   function getip() {
4.  
   if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP") , "unknown")) {
5.  
   $ip = getenv("HTTP_CLIENT_IP");
6.  
   } else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR") , "unknown")) {
7.  
   $ip = getenv("HTTP_X_FORWARDED_FOR");
8.  
   } else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR") , "unknown")) {
9.  
   $ip = getenv("REMOTE_ADDR");
10.  
    } else if (isset($_SERVER[‘REMOTE_ADDR‘]) && $_SERVER[‘REMOTE_ADDR‘] && strcasecmp($_SERVER[‘REMOTE_ADDR‘], "unknown")) {
11.  
    $ip = $_SERVER[‘REMOTE_ADDR‘];
12.  
    } else {
13.  
    $ip = "unknown";
14.  
    }
15.  
    return $ip;
16.  
    }
17.  
    //获取地址
18.  
    function getLocation($ip = ‘‘) {
19.  
    empty($ip) && $ip = getip();
20.  
    if ($ip == "127.0.0.1") return "本机地址";
21.  
    $api = "http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=$ip"; //请求新浪ip地址库
22.  
    $json = @file_get_contents($api);
23.  
    $arr = json_decode($json, true);
24.  
    $country = $arr[‘country‘];
25.  
    $province = $arr[‘province‘];
26.  
    $city = $arr[‘city‘];
27.  
    if ((string)$country == "中国") {
28.  
    if ((string)($province) != (string)$city) {
29.  
    $_location = $province . $city;
30.  
    } else {
31.  
    $_location = $country . $city;
32.  
    }
33.  
    } else {
34.  
    $_location = $country;
35.  
    }
36.  
    return $_location;
37.  
    } ?>

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();?>
