PHP - Facial Detection

Hi guys,

I am creating a script as I am using this to detection the proxy server levels.

<?php
//proxy levels
//Level 3 Elite Proxy, connection looks like a regular client
//Level 2 Anonymous Proxy, no ip is forworded but target site could still tell it's a proxy
//Level 1 Transparent Proxy, ip is forworded and target site would be able to tell it's a proxy
 
if(!$_SERVER['HTTP_X_FORWARDED_FOR'] && !$_SERVER['HTTP_VIA'] && !$_SERVER['HTTP_PROXY_CONNECTION']){
echo '3';
} elseif(!$_SERVER['HTTP_X_FORWARDED_FOR']){
echo '2';
} else echo '1';
?>


I want the script to check the ip that if the proxy server is a Codeen/PlanetLab and BotNet proxy servers, then place on level one and if they are safe/unsafe to use. I cannot find the code to do the methods.


Please help me!

Thanks in advance.

Here is my simple script for user browser and OS detection:
  $agent = $_SERVER['HTTP_USER_AGENT'];
  
  if (strstr($agent,"Windows")) {$os = "Windows";}
  if (strstr($agent,"Windows NT 6")) {$os = "Windows 7";}
  if (strstr($agent,"Linux")) {$os = "Linux";}
  if (strstr($agent,"Intel Mac OS X")) {$os = "OS X";}
  if (strstr($agent,"OpenBSD")) {$os = "BSD";}
  if (strstr($agent,"FreeBSD")) {$os = "FreeBSD";}
  
  if (strstr($agent,"Firefox/3")) {$br = "Firefox 3";}
  if (strstr($agent,"Firefox/2")) {$br = "Firefox 2";}
  if (strstr($agent,"Firefox/1")) {$br = "Firefox 1";}
  if (strstr($agent,"Phoenix/")) {$br = "Phoenix (Mozilla lite)";}
  if (strstr($agent,"MSIE 6")) {$br = "IE 6";}
  if (strstr($agent,"MSIE 7")) {$br = "IE 7";}
  if (strstr($agent,"MSIE 8")) {$br = "IE 8";}
  if (strstr($agent,"Netscape6/6")) {$br = "Netscape 6";}
  if (strstr($agent,"Opera")) {$br = "Opera";}
  if (strstr($agent,"Opera") and strstr($agent,"Version/10")) {$br = "Opera 10";}
  if (strstr($agent,"Opera") and strstr($agent,"Version/9")) {$br = "Opera 9";}
  if (strstr($agent,"Chrome") and strstr($agent,"Chrome/5")) {$br = "Chrome 5";}
  if (strstr($agent,"Safari/")) {$br = "Safari";}
  if (strstr($agent,"Safari/") and strstr($agent,"Version/5")) {$br = "Safari 5";}
  if (strstr($agent,"Safari/") and strstr($agent,"Version/4")) {$br = "Safari 4";}
  if (strstr($agent,"Safari/") and strstr($agent,"Version/3")) {$br = "Safari 3";}
  if (strstr($agent,"SeaMonkey/") and strstr($agent,"Gecko")) {$br = "SeaMonkey";}

  echo "Browser: <b>$br</b>, OS: <b>$os</b>";
I found some information from he http://www.zytrax.com/tech/web/browser_ids.htm

Is there any better solution for this, or script above is accurate?

Hello,

I will tell you whant I want to do first and what I've done so far and hopefuly someone will be able to help.

What I hope for is to have one unique index.php that will work everywhere.  I don't mind if I have to modify each and add path where it is located since this won't happen often.

It needs to take car of preferred language and if someone land in a directory, I want it to load the index.php there.

I also look to not expose hidden URL in the browser URL box.  See *note 1 below.

My directory structure is as follow:

/index.php
/about/index.php
/blahblah/index.php

The current index.php I'm trying to build looks like this:

<?php
    if (preg_match('/^www.(.+)$/i', $_SERVER['HTTP_HOST'], $matches)) {
      header("Status: 301 Move permanently", false, 301);
      header('Location: http://'.$matches[1].$_SERVER['REQUEST_URI']);
      exit;
    }

    session_start();
    $Lang = $_SESSION['lang'];
    
    if (!isset($Lang))
         {
        if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE']))
            {
            $Lang = explode(",",$_SERVER['HTTP_ACCEPT_LANGUAGE']);
            $Lang = strtolower(substr(chop($Lang[0]),0,2));
            if ($Lang !== 'fr' && $Lang !== 'en')
                { 
                $Lang = "en";
                }
            }
        else
            {
      $Lang = "en";
            }
        $_SESSION['lang'] = $Lang;
        }

    include $_SERVER["DOCUMENT_ROOT"] . ("/index_" . $_SESSION['lang'] . ".php");
?>

First I remove "www." in the address when applies.  Not a must but I like that.

Then I check if Language is already set, if not I detect and set it for next pages.

I finally load the proper page according to language with an "include" so index_en.php remain secret (sort of).

*note 1: all my index_xx.php pages in every directory have this: Code: [Select]
<script language="javascript" type="text/javascript">
        if (self == top)
        top.location.href="directory/index.php";
    </script>

When in the root, it seems to work and I get the proper page but if I place this in /about/ then when I tried to load /about/index.php it doesn't work.  I think the include on the last line could be the problem.

I'm either close or far from it, I don't know.

Thank you.

I was on a proxy and it didnt detect it, idk why.


  if(!empty($_SERVER['HTTP_X_FORWARDED_FOR'])
    || !empty($_SERVER['HTTP_X_FORWARDED'])
    || !empty($_SERVER['HTTP_FORWARDED_FOR'])
    || empty($_SERVER['HTTP_CONNECTION'])
    || $hostaddr == "."
    || stripos($hostaddr, "tor-exit")
    || !empty($_SERVER['HTTP_VIA'])
    || empty($_SERVER['HTTP_ACCEPT_ENCODING'])
    || in_array($_SERVER['REMOTE_PORT'], array(8080,80,6588,8000,3128,553,554))
    ) {
    die('on Proxy');

Hello

Has anyone managed to create a php script that will detect and list the AddOns in a browser such as Firefox or Chrome?   I need to know if a user has a particular extension loaded and if it is disabled or enabled.

Hi guys,

Guys:  I'm implementing a form for user submission.  At the end of the form, there is an image that displays some randomly generated code.  The user will be required to enter the code shown on this image before he clicks the submit button.  This is done to protect the form from spamming, automatic submission. 

After the submit button is clicked, I need to do this:

if ($_POST['the code the user enters'] == the code on the image) {
   // proceed();
}
 
Any idea on how to get the code displayed on the image ?  Thanks.

Hi, I came across this code that detects a user's browser and I don't understand parts of it. Here is the code below.

Code: [Select]
$agent = $_SERVER['HTTP_USER_AGENT'];

if ( strpos(strtoupper($agent), 'MSIE')) {
print "Internet Explorer";
}
else if (strpos(strtoupper($agent), 'FIREFOX')) {
print "Firefox";
}
else if (strpos(strtoupper($agent), 'KONQUEROR')) {
print "Konqueror";
}
else if (strpos(strtoupper($agent), "LYNX")) {
print "Lynx";
}
else {
print $agent;
}
and here is the part I don't understand.

Code: [Select]
if ( strpos(strtoupper($agent), 'MSIE'))
I know that strtoupper makes all letters uppercase,
and that strpos returns the position of the string within
the larger string, but I don't know why they are in an if
statement.  Any help or explanation is greatly appreciated. Thanks. Derek

Hi Everyone:

Can anyone show me or direct me to a PHP PHP Mobile Device Detection & Redirection Script.

I use to use this when doing ASP:
Code: [Select]
<%

Dim user_agent, mobile_browser, Regex, match, mobile_agents, mobile_ua, i, size
 
user_agent = Request.ServerVariables("HTTP_USER_AGENT")
 
mobile_browser = 0
 
Set Regex = New RegExp
With Regex
   .Pattern = "(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|windows ce|pda|mobile|mini|palm)"
   .IgnoreCase = True
   .Global = True
End With
 
match = Regex.Test(user_agent)
 
If match Then mobile_browser = mobile_browser+1
 
If InStr(Request.ServerVariables("HTTP_ACCEPT"), "application/vnd.wap.xhtml+xml") Or Not IsEmpty(Request.ServerVariables("HTTP_X_PROFILE")) Or Not IsEmpty(Request.ServerVariables("HTTP_PROFILE")) Then
   mobile_browser = mobile_browser+1
end If
 
mobile_agents = Array("w3c ", "acs-", "alav", "alca", "amoi", "audi", "avan", "benq", "bird", "blac", "blaz", "brew", "cell", "cldc", "cmd-", "dang", "doco", "eric", "hipt", "inno", "ipaq", "java", "jigs", "kddi", "keji", "leno", "lg-c", "lg-d", "lg-g", "lge-", "maui", "maxo", "midp", "mits", "mmef", "mobi", "mot-", "moto", "mwbp", "nec-", "newt", "noki", "oper", "palm", "pana", "pant", "phil", "play", "port", "prox", "qwap", "sage", "sams", "sany", "sch-", "sec-", "send", "seri", "sgh-", "shar", "sie-", "siem", "smal", "smar", "sony", "sph-", "symb", "t-mo", "teli", "tim-", "tosh", "tsm-", "upg1", "upsi", "vk-v", "voda", "wap-", "wapa", "wapi", "wapp", "wapr", "webc", "winw", "winw", "xda", "xda-")
size = Ubound(mobile_agents)
mobile_ua = LCase(Left(user_agent, 4))
 
For i=0 To size
   If mobile_agents(i) = mobile_ua Then
      mobile_browser = mobile_browser+1
      Exit For
   End If
Next
 
 
If mobile_browser>0 Then
   Response.Redirect("http://www.sp.com/SPMOBI/MOBI.asp")
End If
 
%>


Is there a PHP equivalent of this?

As always, I appreciate to wisdom of the board.

Thanks!

Can I rely on the $_SERVER variable of HTTP_ACCEPT_LANGUAGE to get the language of the browser? I know that some browsers don't send things the same way, and even some servers may not use all variables. Is this the most common way to determine the user's language? Is there another or more preferred way?   Thank you.
