Answer 1

Replace

if ($detect->isMobile()) {$mobile = '1';}

With

if ($detect->isMobile()) {$mobile = '1';}

See if that works

Answer 2

You have a problem with mismatched quotes as well as with your -&gt. Try

if ($detect->isMobile()) {$mobile = '1';}

instead

With your mismatched quotes, use

echo '<link href="'+$site+'css/mobile.css" rel="stylesheet">';

This is what i did and it works.

// Include and instantiate the class.
require_once 'php/mobile_detect.php';

$detect = new Mobile_Detect();
if ($detect->isMobile()) {$mobile = '1';}

if ($mobile == 1) {
    echo '<link href="css/mobile.css" rel="stylesheet">';
}else {
    echo '<link href="css/custom.css" rel="stylesheet">';
    }

?>
