The only time I'd be looking at whether content of $somearray['somekey']
== TRUE is when it's possible that it may contain something other than
TRUE or FALSE, and somehow my code *cares* whether it does. In this
case, we do not, your rant holds.

This is most egregious.

This would even be a case where I'd opt for:
$isMobile = @$browser['ismobiledevice'];
since if it *isn't* set, it's still falsy, with the rather strong caveat
of don't use @ indiscriminantly.

Argh!, Argh!, Argh! -- two of my pet hates in one snippet!
Comparing something ==TRUE is almost always unnecessary, and absolutely always
when it's used as an element of a Boolean expression: if x evaluates to TRUE,
x==TRUE is also TRUE, and if it evaluates to FALSE x==TRUE is also FALSE, so
the comparison is unnecessary, redundant and wasteful. Just use x.
And why use an if test on a Boolean value to see if it's TRUE or FALSE, just so
you can assign TRUE or FALSE?? Since the thing you're testing has the value you
want in the first place, just flipping assign it!
$isMobile = isset($browser['ismobiledevice']) && $browser['ismobiledevice'];
Cheers!

Tests came out as follows: php-mobile-detect: 7 seconds in 15.000 devices, 70% accuracy detectmobilebrowsers.com: 0.6 seconds in 15.000 devices, 93,5% accuracy The post I made is in spanish, but could serve as a reference: http://blog.unreal4u.com/2012/10/detectar-facilmente-un-dispositivo-movil/ As for the OP, I think that the best way would be PHP, because you can do a lot more, like not even redirecting the user but rather just load the mobile site directly, setting a session value if desktop version is forced or not. This way, any links would also be interchangeable, making it easier for you to implement specific functionality such as "send link through email" and other related things.

Hello, I stumbled upon this the other day : http://mobiledetect.net/ I haven't tried it yet, since I have my own small user agent parser when I need it, but it may help you if it's a pure php solution you're looking for.

I forgot to mention, in PHP the user agent string is in
$_SERVER['HTTP_USER_AGENT'], and in javascript you can find it in
navigator.userAgent.
Where you want to redirect, it's up to you. If you want it to do on first
attempt, better go with PHP so you can use Header("Location: ...") to
redirect the user immediately so the user won't notice he is being
redirected.

Any Android device will have Android in it's user agent, and iPhone as iPhone in the User Agent string. If you want to check for tablets, you can check for iPad specifically (it is in the user agent), and for Android, I believe that mobile devices have 'Mobile' in the user agent string, and tablets don't. Then there is ofcourse the small 1 percent or so Blackberry & WP users, which can probably be detected easily too with their user agent. Cheers, Matijn

A few line in your vcl configuration and there you go. You can even put a rules to indicate that if there is a GET parameter or a cookie, you don't redirect the user. It means that you can simply add a link on your mobile website to send the user back on the desktop website if he prefers. I like this approach as it is directly on your first frontend (or load balancer) and you don't even need to load you php app to redirect the user. Regards, -- bacardi55 (bacardi55.org)

This is not really a PHP question. I understand your asking it, though. Does anyone know of a better list or whatever for generic web designer questions? To your question, there are two problems: 1) Looking for a browser signature is a needle/haystack proposition, and the haystack is enormous, and it gets bigger every time a new phone/tablet model comes out; 2) Screen size used to be a good indicator, but as I feared when people first started using screen resolution as the main indicator, the screens on mobile devices have become progressively more and more capable. Some of them are better than many desktops I've seen. So I'd be interested in the answer to the question myself. Paul -- Paul M.
