1 获取当前访客用户画像信息

php可以获取当前访客的ip地址，所访问的页面url，入口页url，访客的操作系统、访客使用何种浏览器访问该页面，这对我们掌握用户特征，调整网站内容结构具有重要的作用。

1.1 获取用户ip地址

通过以下代码获取用户ip地址

// 获取访问者IP地址
$ip = '0.0.0.0';
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";
}

1.2 获取操作系统类型

通过以下代码获取用户操作系统类型

$userAgent = empty($_SERVER['HTTP_USER_AGENT']) ? 'null' : $_SERVER['HTTP_USER_AGENT'];

if(false !== stripos($userAgent, 'Android')){
    $system = "Android";
}else if(false !== stripos($userAgent, 'Windows Phone')){
    $system = "Windows Phone";
}else if(false !== stripos($userAgent, 'Windows NT')){
    $system = "Windows";
}else if(preg_match($ios_regex, $userAgent)){
    $system = "IOS";
}else if(false !== stripos($userAgent, 'Mac')){
    $system = "MacOS";
}else if(false !== stripos($userAgent, 'Linux')){
    $system = "Linux";
}else if(false !== stripos($userAgent, 'Unix')){
    $system = "Unix";
}

1.3 获取用户使用的浏览器类型

通过以下代码获取用户浏览器类型

    $client = "百度app";
}else if(stripos($userAgent, 'weibo')){
    $client = "WeiBo";
}else if(stripos($userAgent, 'iqiyi')){
    $client = "爱奇艺";
}else if(stripos($userAgent, 'aweme')){
    $client = "抖音";
}else if(stripos($userAgent, 'kdtUnion_iting')){
    $client = "喜马拉雅";
}else if(stripos($userAgent, 'UCBrowser')){
    $client = "UC";
}else if(stripos($userAgent, 'DingTalk')){

    $client = "Safari";
}else if(preg_match($ie_regex, $userAgent)){
    $client = "IE";
}

1.4 获取用户所使用的语言

通过以下代码获取用户所使用的语言
