Mobile devices detect

Question

I have some page, but i need that users with randow user-agent (browsers or tablet, pc,..) see random info. I need to detect some device and do a manipulation with this info. For example, for iOS users i have one kind of info, for android another, and so on... Also for pc/laptop user includes one kind of css (even logos, events, scripts,...) for android another css, for blackberry another css and so on.

I think it's very important for absolutely responsive design.

Answer 1

So... I did it like this... Create a detect.php file and include it to a document. If someone have ideas about it.. please...

<?php

$useragent = $_SERVER['HTTP_USER_AGENT']; //- Check user browser

//-- Create a variable
$DEVICE = ($iPod||$iPad||$iPhone||$Android||$iOS||$webOS||$Blackberry||$IEMobile||$OperaMini||$Dolphin||$Meego||$Avantgo||$Bada||$Blazer||$Compal||$Elaine||
$Fennec||$Hiptop||$Iris||$Kindle||$Lge||$Maemo||$Midp||$Mmp||$Netfront||$OperaMobi||$Palm||$PalmOS||$Phone||$Plucker||$Pocket||$Psp||$Symbian||$Treo||$Wos||

$GoBrowser||$uZardWeb||$Doris||$Skyfire||$CLDC||$MobileSafari);

?>

Now you can use it like:

1. Include this file to all file that need to detect user device; you can include it once if you need For example: include_once ("path_to_file/detect.php");

2. Use variable $DEVICE anywhere you need infinity times like:

   <?php if (!$DEVICE) {echo 'This is for all desktop devices text';} else {echo 'This is for all mobile text';}
   ?>
   

or

!!! Also you can use it like this (if you need to separate info to different devices)

<?php if ($DEVICE=$iPhone) {echo 'This is for iphone devices text';} else if ($DEVICE=$Blackberry) {echo 'This is for Blackberry text';}
?>

That's it. All ingenious is simple! Use it and be happy! */ ?>
