How to check if the web page is visited by a phone browser or a PC browser?

Question

How to check if a web page has been opened by a mobile browser or a computer browser. I tried this :

name = request.getHeader(\"User-Agent\");

Answer 1

Like Mikko wrote, no simple ways to detect mobile.

But you can try: http://code.google.com/p/php-mobile-detect/

And something like previous answer: http://detectmobilebrowsers.com/

Answer 2

There is not any simple 'mobile=true' flag. You simply have to check by yourself. From here you can find subset of of values to search (list is rather old, so newer mobile browsers should be added).

Answer 3

this is a good link I just found:

http://www.abeautifulsite.net/blog/2011/11/detecting-mobile-devices-with-javascript/

var isMobile = {
    Android: function() {
        return navigator.userAgent.match(/Android/i);
    },
    BlackBerry: function() {
       return navigator.userAgent.match(/BlackBerry/i);
    },
    iOS: function() {
        return navigator.userAgent.match(/iPhone|iPad|iPod/i);
    },
    Opera: function() {
        return navigator.userAgent.match(/Opera Mini/i);
    },
    Windows: function() {
        return navigator.userAgent.match(/IEMobile/i);
    },
    any: function() {
        return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() ||      isMobile.Opera() || isMobile.Windows());
    }
};

You could also look at the size of the screen (smaller size would possibly mean a mobile device), which should be accessible through javascript.
