PHP 获取访客IP 浏览器 语言
PHP 简单的获取 User Agent 信息代码:echo $_SERVER['HTTP_USER_AGENT'];
浏览器判断
此代码只能简单的对一些主流浏览器进行识别，其他浏览器我们可以通过加入多个判断的形式进行识别
<?php
function GetBrowser() {
if (!empty($_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 "0";
}} ?>
IP获取
<?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 $ip;}
语言判断
<?php
function GetLang() {
if (!empty($_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 "0";
}} ?>
