Check For Mobile Browser

I want to create a mobile version of my website, and I need to know how to check for mobile browsers. I am thinking of creating an iPhone specific one too. I looked around and all I really found were shaky solutions that didn't check very well. I think that PHP would be the best language to check, as it is pretty universally supported, however, if there is a more efficient way to check in another language then please tell me!

I think most "mobile" websites have two versions, of which the mobile one would use a different link. Instead of "checking" to see if it's mobile, the user would have to manually use the other address.

For example, with Gmail there is gmail.com and the other is mobile.gmail.com I think. Or it's something like that.

I will have a dedicated address for it, too, but I also want it to check for the mobile browsers and direct it to the mobile site or at least a page to choose whether or not to go to the mobile site. That way if somebody doesn't know there is a mobile version, they have the chance to learn about it.

If you are using PHP then you can use the session variable (I think thats what its called) $_SERVER['HTTP_USER_AGENT']. This will return a string with various values depending on the user agent of the client.

Now you just need to code what type of broswers your looking for and since its mobile broswers your after heres a list of user agents so far. http://www.zytrax.com/tech/web/mobile_ids.html

Use preg_match() to check and redirect as needed.

heres a sample of my code below. I think yours will have to be much longer to include all mobile browsers. That is if you want to check for all right?
CODE
$ua = $_SERVER['HTTP_USER_AGENT'];
$pattern = "/msie\s(5\.[5-9]|6\.[0-9])/i";
if(preg_match($pattern,$ua))
{
    header("location: redirect.php");
}


edit: I'm not sure if preg_match can take arrays as the pattern, if it can then you can setup an array of all those broswer strings. easy smile.gif.

Update:***

Actually someone has already written some code for this. http://detectmobilebrowsers.mobi/ I think this would be alot easier then trying to preg_match all on your own. GL

Yes i also suggest that if u can check the browser id and match it with the mobile site you want to load. In simple programming language just get some mobile ids and use a if statement for each id. Say for eg if u a user comes to your site via opera mini then t just check his id and match it with the site u optimized with opera and start that page. Thats all hope i helped

Apache Mobile Filter
Check For Mobile Browser

I have published a new mode to detect devices in any programming language (JSP, PHP, Perl, Python...), it's called Apache Mobile Filter is an Apache module (http://modules.Apache.Org/search.Php?id=1787) that detect mobile device and also can adapt the images to the screen size of device.

i think todays mobile browsers have the enough capability to handle big pages.like opera mini or bolt browser.it can show you the pages as you are watching it in your pc with a minor limitation.only the problem is small screens.
so many times i have made payments and watched online movies also with this bolt browser.so whats the need to make a mobile site fro your web site.any way,if you create it.y dont you make it with m.domain name.your tld (like m.trap17.com) it looks good also and anyone can understand that it is for mobile only.all the best

  6. Browser Problems, Maybe?
    Firefox vs IE (6)
    Alright, I coded something the other day for the game I am working on making, and a few of my
    friends I allowed to get on it and test things out. Well....the ones that were on IE their
    characters were made but the User variable as in which account they were on just stayed blank, while
    with my friends that were on Firefox, everything worked fine and they could play perfectly... So I
    was wondering, with PHP sql codes being sent to the database, is there something special you have to
    do to make it work on both, or could it be a setting on the IE that was messing with it......
