Why doesn't this Mobile_Detect.php work?

I may be overlooking something very basic, but it's late and I wouldn't mind another set of eyes on it.

Here's my header on http://loosecannonfitness.com...

include 'Mobile_Detect.php';
$detect = new Mobile_Detect();
if ($detect->isMobile()) {
// Any mobile device.
header("Location:mobile/index.php");
exit();
}

The file is attached. I'm using the same dynamic on http://brucegust.com and the redirect works fine. For some reason, it's not working on loosecannonfitness.com.

Why?

I can't readily tell you how to fix this, but I can give you some reasons why it might not work.  And some ideas about how to move forward with something that works for mobile support.

There is a single class with more than 700 lines of code.  It has 22 if() statements.  It appears to be highly dependent on hard-coded data and regular expressions.  This is where the testers come running into the room screaming, "Cyclomatic Complexity!" I can't even begin to estimate how long it would take to write the unit tests for something like this.  The introduction of any new mobile device, by any vendor, anywhere in the world will require code changes.  In short, I would look for another solution, because this is "one of those things" we don't ever want to deal with!

Instead, you might want to adopt a "mobile first" design strategy instead of "if mobile, go elsewhere."  The basic tenets of mobile first design are pretty simple.  We acknowledge that mobile traffic must be supported first, because it is the growth area of internet communication.  Wireless mobile traffic exceeded desktop traffic in 2012 and has been widening its lead over tethered traffic ever since.  So if there are specific things that we need to do for the desktop, we add those later, after our mobile design works well.  The desktop is an afterthought in modern web design, full stop.

Cross browser design technologies such as those from Twitter Bootstrap can help a lot.  FontAwesome is a nice addition.  React and AngularJS might be helpful, too.

Hey, Ray!

As always, I appreciate your willingness to weigh in. I did figure it out. It had nothing to do with the script. I was proceeding assuming that the header was, in fact, a part of the index page. It was not. Once that was determined, the sun shined, the birds began to sing and the French Horns began to play in the distance.

Morons, your bus is leaving...
