从php中的输入字段返回OS信息/名称

Question

帮助家伙!!!

基本上我想从输入栏中返回/显示用户操作系统信息/名称......

在我未完成的剧本下面..

<?php

$user_agent     =   $_SERVER['HTTP_USER_AGENT'];

function getOS() { 

global $user_agent;

$os_platform    =   "Unknown OS Platform";

$os_array       =   array(
                        '/windows nt 6.2/i'     =>  'Windows 8',
                        '/windows nt 6.1/i'     =>  'Windows 7',
                        '/windows nt 6.0/i'     =>  'Windows Vista',
                        '/windows nt 5.2/i'     =>  'Windows Server 2003/XP x64',
                        '/windows nt 5.1/i'     =>  'Windows XP',
                        '/windows xp/i'         =>  'Windows XP',
                        '/windows nt 5.0/i'     =>  'Windows 2000',
                        '/windows me/i'         =>  'Windows ME',
                        '/win98/i'              =>  'Windows 98',
                        '/win95/i'              =>  'Windows 95',
                        '/win16/i'              =>  'Windows 3.11',
                        '/macintosh|mac os x/i' =>  'Mac OS X',
                        '/mac_powerpc/i'        =>  'Mac OS 9',
                        '/linux/i'              =>  'Linux',
                        '/ubuntu/i'             =>  'Ubuntu',
                        '/iphone/i'             =>  'iPhone',
                        '/ipod/i'               =>  'iPod',
                        '/ipad/i'               =>  'iPad',
                        '/android/i'            =>  'Android',
                        '/blackberry/i'         =>  'BlackBerry',
                        '/webos/i'              =>  'Mobile'
                    );

foreach ($os_array as $regex => $value) { 

    if (preg_match($regex, $user_agent)) {
        $os_platform    =   $value;
    }

}   

return $os_platform;

}

function getBrowser() {

global $user_agent;

$browser        =   "Unknown Browser";

$browser_array  =   array(
                        '/msie/i'       =>  'Internet Explorer',
                        '/firefox/i'    =>  'Firefox',
                        '/safari/i'     =>  'Safari',
                        '/chrome/i'     =>  'Chrome',
                        '/opera/i'      =>  'Opera',
                        '/netscape/i'   =>  'Netscape',
                        '/maxthon/i'    =>  'Maxthon',
                        '/konqueror/i'  =>  'Konqueror',
                        '/mobile/i'     =>  'Handheld Browser'
                    );

foreach ($browser_array as $regex => $value) { 

    if (preg_match($regex, $user_agent)) {
        $browser    =   $value;
    }

}

return $browser;

}

$user_os        =   getOS();
$user_browser   =   getBrowser();

$device_details =   "Operating System: </strong>".$user_os."";

print_r($device_details);
?>

以上脚本运行时运行良好... 它将显示我的操作系统版本

但问题是，我想创建一个输入字段，以便用户可以键入任何IP地址，如果有效，则上面的脚本将显示操作系统信息/名称无效......

以上脚本使用.. $ user_agent = $ _SERVER ['HTTP_USER_AGENT'];自动显示操作系统信息/名称......

但是我想从输入字段手动键入IP，上面的脚本将在输入字段中显示相应的OS信息/名称......

如何更改上面的脚本...尤其是$ user_agent = $ _SERVER ['HTTP_USER_AGENT'];所以它可以从输入字段返回IP地址??

如果你们想帮帮忙，我非常荣幸...... :(
