An easy way to detect a mobile or desktop device in PHP is to check if the HTTP user agent contains the word “mobile”. $ua = strtolower($_SERVER["HTTP_USER_AGENT"]); $isMob = is_numeric(strpos($ua, "mobile"));
In summary, we recommend looking for the string “Mobi” anywhere in the User Agent to detect a mobile device. Like this: if (/Mobi/. test(navigator.
Device Detection is technology that identifies what type of mobile devices are accessing an organization's website. That organization can run device detection in real time, or run it as post-processing data analysis.
In ASP.NET, you can easily detect the mobile device request using Request. Browser. IsMobileDevice property and Request. UserAgent .

$useragent=$_SERVER['HTTP_USER_AGENT'];

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", $_SERVER["HTTP_USER_AGENT"]);
}
// If the user is on a mobile device, redirect them
if(isMobile()){
header("Location: http://m.yoursite.com/");
}
Let me know if you have any questions and good luck!
I found mobile detect to be really simple and you can just use the isMobile() function :)
function isMobileDev(){
if(!empty($_SERVER['HTTP_USER_AGENT'])){
$user_ag = $_SERVER['HTTP_USER_AGENT'];
if(preg_match('/(Mobile|Android|Tablet|GoBrowser|[0-9]x[0-9]*|uZardWeb\/|Mini|Doris\/|Skyfire\/|iPhone|Fennec\/|Maemo|Iris\/|CLDC\-|Mobi\/)/uis',$user_ag)){
return true;
};
};
return false;
}
I was wondering, until now, why someone had not posted a slightly alteration of the accepted answer to the use of implode() in order to have a better readability of the code. So here it goes:
<?php
$uaFull = strtolower($_SERVER['HTTP_USER_AGENT']);
$uaStart = substr($uaFull, 0, 4);

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.
