PHP user agent determining for both mobile and tablet

Question

i use this:

    $isMobile = (bool) strpos($_SERVER['HTTP_USER_AGENT'],'Mobile');

    if ($isMobile) {
        $Ymobile = "block";
    } else {
        $Ymobile = "none";
    }

This determines if the user is on mobile device, if yes it sets the class of a div to block.

However for a tablet, the div is shown.

So i changed the 'Mobile' to 'Tablet' and it worked, the div didnt show on the tablet.

How come the else doesnt hide the div on a tablet?

I thought i could do e.g.:

    $isMobile = (bool) strpos($_SERVER['HTTP_USER_AGENT'],'Mobile');
    $isTablet = (bool) strpos($_SERVER['HTTP_USER_AGENT'],'Tablet');

    if ($isMobile) {
        $Ymobile = "block";
    } else if ($isTablet) {
        $Ymobile = "none";
    } else {
        $Ymobile = "none";
    }

But that still shows the div.

Where am i going wrong?

Just an idea..

Why don't you try a switch statement. If no 'Mobile' is detected then set none, in all other cases (is Mobile) then go for "block"

switch(strpos($_SERVER['HTTP_USER_AGENT'],'Mobile')) {
    case false:
        $Ymobile = "none";
        break;
    default:
        $Ymobile = "block";
        break;
}

Very simple to use with tons of options.
