How to Use userAgent to detect mobile device

Question

Can anyone help me with this.

I would like to detect device such as Iphone, BB, andriod and browser to apply their specific css to make it liquefied or adjust to th

Answer 1

Try to use http://www.php.net/get_browser and check for isMobileDevice field. It might help only, of course, if the path to browscap.ini is set up in php.ini. If not, you can use php classes like https://github.com/garetjax/phpbrowscap

Answer 2

You can use CSS Media Queries to identify the different devices (actually the different device features like device-width, dpi, etc)

For the CSS, you can have different options like having separate CSS for each type of device OR having a fluid design which would mean having the same CSS scale for different device sizes. The 2nd approach is slightly complex to design, but is much more flexible from new devices that may come up in future..

Answer 3

I use this:

$mobile= stripos( $_SERVER['HTTP_USER_AGENT'], 'mob');

It works almost every time.

Javascript

var mobile= navigator.userAgent.toLowerCase().indexOf( 'mob');

-1 if not mobile; any other value if mobile

Answer 4

<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;  user-scalable=0;" />
<meta name="HandheldFriendly" content="true"/>
<meta name="MobileOptimized" content="320"/>
<meta http-equiv="cleartype" content="on" />


use this code on your website under <header> tag.

Here is the code for the mobile device detection.

 function isMobile() {

// Check the server headers to see if they're mobile friendly
if(isset($_SERVER["HTTP_X_WAP_PROFILE"])) {
    return true;
}

// If the http_accept header supports wap then it's a mobile too
if(preg_match("/wap\.|\.wap/i",$_SERVER["HTTP_ACCEPT"])) {
    return true;
}

// Still no luck? Let's have a look at the user agent on the browser. If it contains
// any of the following, it's probably a mobile device. Kappow!
if(isset($_SERVER["HTTP_USER_AGENT"])){
    $user_agents = array("midp", "j2me", "avantg", "docomo", "novarra", "palmos", "palmsource", "240x320", "opwv", "chtml", "pda", "windows\ ce", "mmp\/", "blackberry", "mib\/", "symbian", "wireless", "nokia", "hand", "mobi", "phone", "cdm", "up\.b", "audio", "SIE\-", "SEC\-", "samsung", "HTC", "mot\-", "mitsu", "sagem", "sony", "alcatel", "lg", "erics", "vx", "NEC", "philips", "mmm", "xx", "panasonic", "sharp", "wap", "sch", "rover", "pocket", "benq", "java", "pt", "pg", "vox", "amoi", "bird", "compal", "kg", "voda", "sany", "kdd", "dbt", "sendo", "sgh", "gradi", "jb", "\d\d\di", "moto");
    foreach($user_agents as $user_string){
        if(preg_match("/".$user_string."/i",$_SERVER["HTTP_USER_AGENT"])) {
            return true;
        }
    }
}

// Let's NOT return "mobile" if it's an iPhone, because the iPhone can render normal pages quite well.
if(preg_match("/iphone/i",$_SERVER["HTTP_USER_AGENT"])) {
    return false;
}

// None of the above? Then it's probably not a mobile device.
return false;
}
    if (isMobile()) {
   header("location:$mobile");
  // if the function returned true, it's a mobile.
  //echo "mobile"; // delete this line in your code, and uncomment the next line
 // header('Location: http://www.yoursite.mobi/'); // let's redirect the page to   the mobile site

   }

Hope this will help you.

Answer 5

Here is an example in javascript:

var isMobile = navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/);

if(isMobile) {
   // User-Agent is IPhone, IPod, IPad, Android or BlackBerry
}

To check for a specific User-Agent string you can do:

if(navigator.userAgent.match(/iPhone/)) {
   // The User-Agent is iPhone
}
