Not using Composer?

If you are not using Composer and still want to use all without including all classes?

use like below sample (assuming the Browser folder in the same folder as your project, otherwise you might want to change the include within the __autoload function to match your location.

function __autoload($class_name)   
{
    $class_name = str_replace("\\","/", $class_name);
    include $class_name . '.php';
}

use Browser\Browser;

$browser = new Browser;

echo $browser->getName();
