Simplest way to detect a mobile device in PHP

Question

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

In case you care about screen size you can store screen width and Height as cookie values if they do not exists yet and then make self page redirection.

Now you have cookies on client and server side and can use it to determine mobile phones, tablets and other devices

Here a quick example how you can do it with JavaScript. Warning! [this code contain pseudo code].

if (!getcookie("screen_size")) {
    var screen_width = screen.width;
    var screen_height = screen.height;
    setcookie("screen_size", screen_width+", " +screen_height);
    go2(geturl());
}

You only need to include user agent php file which can be found from Mobile device detection in PHP page and use the following code    lt  php   include file include once  user agent php      create an instance of UserAgent class  ua   new UserAgent       if site is accessed from mobile  then redirect to the mobile site  if  ua- gt is mobile        header  Location http   m codexworld com       exit      gt

Maybe combining some javascript and PHP could achieve the trick  lt  php  string     lt script gt     string     if    Opera OPR   Puffin Android webOS iPhone iPad iPod BlackBerry IEMobile Opera Mini i test navigator userAgent         string             alert  quot CELL quot      string           else      string             alert  quot NON CELL quot      string                       string      lt  script gt     echo  string    gt   I used that with plain javascript also instead

I wrote this script to detect a mobile browser in PHP   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

You could also use a third party api to do device detection via user agent string  One such service is www useragentinfo co  Just sign up and get your api token and below is how you get the device info via PHP    lt  php  useragent     SERVER  HTTP USER AGENT       get api token at https   www useragentinfo co   token     lt api-token gt     url    https   www useragentinfo co api v1 device      data   array  useragent    gt   useragent     headers   array     headers      Content-type  application json    headers      Authorization  Token      token    curl   curl init  url   curl setopt  curl  CURLOPT HEADER  false   curl setopt  curl  CURLOPT RETURNTRANSFER  true   curl setopt  curl  CURLOPT HTTPHEADER   headers   curl setopt  curl  CURLOPT POST  true   curl setopt  curl  CURLOPT POSTFIELDS  json encode  data      json response   curl exec  curl     status   curl getinfo  curl  CURLINFO HTTP CODE    if   status    200         die  Error  call to URL  url failed with status  status  response  json response  curl error     curl error  curl       curl errno     curl errno  curl       curl close  curl    echo  json response    gt    And here is the sample response if the visitor is using an iPhone        device type   SmartPhone      browser version   5 1      os   iOS      os version   5 1      device brand   Apple      bot  false     browser   Mobile Safari      device model   iPhone

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
