Detect Mobile Browsers | Open source mobile phone detection

What is the simplest way to tell if a user is using a mobile device to browse my site using PHP?
I have come across many classes that you can use but I was hoping for a simple if condition!
Is there a way I can do this?

You could put a javascript in the page that checks the screen resolution, but that would be client-side:howtocreate.co.uk/tutorials/javascript/browserwindow –  thejh Nov 7 '10 at 11:55

Thanks for that, one of the biggest if conditions I have seen but its simple! –  Abs Nov 7 '10 at 13:48
   
Could HTTP_USER_AGENT be faked? –  kavoir.com May 25 at 12:54
   
awesome! good answer =) –  Daniel Garcia Sanchez Jun 1 at 7:06
The code detects a user based on the user-agent string by preg_match()ing words that are found in only mobile devices user-agent strings after hundreds of tests. It has 100% accuracy on all current mobile devices and I'm currently updating it to support more mobile devices as they come out. The code is called isMobile and is as follows:
function isMobile() {
    return preg_match("/(android|avantgo|blackberry|bolt|boost|cricket|docomo|fone|hiptop|mini|mobi|palm|phone|pie|tablet|up\.browser|up\.link|webos|wos)/i", $_SERVER["HTTP_USER_AGENT"]);
}
You can use it like this:
// Use the function
if(isMobile()){
    // Do something for only mobile users
}
else {
    // Do something for only desktop users
}
To redirect a user to your mobile site, I would do this:
// Create the function, so you can use it
function isMobile() {
    return preg_match("/(android|avantgo|blackberry|bolt|boost|cricket|docomo|fone|hiptop|mini|mobi|palm|phone|pie|tablet|up\.browser|up\.link|webos|wos)/i", $_SERVER["HTTP_USER_AGENT"]);
}
// If the user is on a mobile device, redirect them
if(isMobile()){
    header("Location: http://m.yoursite.com/");
}
Let me know if you have any questions and good luck!

Just FYI: you should not continue to post this duplicate answer to posts you find here looking for mobile browser detection. –  Andrew Barber Jun 12 '12 at 1:47
   
I've closed the duplicates. –  Robert Harvey Jun 12 '12 at 1:50
   
@RobertHarvey - im confused. they are all asking basically the same thing so what am i supposed to do, other than answer the question? tell them to use something else each time? i'm new here so im not sure if im supposed to link to the first answer? –  Justin DoCanto Jun 13 '12 at 3:42 
   
This keyword "tablet" is creating me a problem on some IE8 (PC) headers that have "Tablet PC 2.0" in response –  Mladen Janjetović Oct 29 '13 at 15:55
PHP device detection from 51Degrees.com does exactly what you want - detects mobile devices and various properties associated with detected devices. It is simple to use and requires no maintenance. Set up is done in 4 easy steps:
  1. Download the Zip file from http://sourceforge.net/projects/fiftyone/.
  2. Unzip the file into a directory in your PHP server.
  3. Then add the following code to your PHP page:
  4. require_once 'path/to/core/51Degrees.php';
    require_once 'path/to/core/51Degrees_usage.php';
  5. All available device information will be contained in $_51d array:
  6. if ($_51d['IsMobile'])
    {
        //Start coding for a mobile device here.
    }
51Degrees device detector does not use regular expressions for detections. Only important parts of HTTP headers are used to match devices. Which makes this solution the fastest (5 000 000 detections per second on mediocre hardware) and most accurate (99.97% accuracy) as hundreds of new devices are added to the database weekly (Supported device types include consoles, smart TVs, e-readers, tablets and more).
Software is open source distributed under Mozilla Public License 2 and compatible with commercial and open source projects. As a bonus 51Degrees solution also contains a complementary PHP image optimiser that can automatically resize images for mobile devices.
By default 51Degrees PHP device detector uses Lite data file which is free and contains over 30000 devices and 50 properties for each device. Lite file is updated once every 3 month. If you want to have a higher level of details about requesting mobile devices, then Premium and Enterprise data files are available. Premium contains well over 70000 devices and 100 properties for each device with weekly updates. Enterprise is updated daily and contains over 150000 devices with 150 properties for each.

There is no reliable way. You can perhaps look at the user-agent string, but this can be spoofed, or omitted. Alternatively, you could use a GeoIP service to lookup the client's IP address, but again, this can be easily circumvented.
