Answer 1

Normally in our projects we do set include path like this:

set_include_path('PATH_TO_GLOBAL_LIBS; PATH_TO_LIBRARY_1; PATH_TO_LIBRARY_X; PATH_TO_DOCUMENT_ROOT');

By this we tell PHP (Apache) to search these paths for any classes that should be included by autoloader.

Then assuming we have some Library_1 in /var/www/Libs/library_1 and that this path is added to the include_path we could do this:

namespace Company\Common;

Class DB {
    private function __construct() {
        $this->Handle = new \Library_1();
    }
}

which should be the same as

namespace Company\Common;

use \Library_1;

Class DB {
    private function __construct() {
        $this->Handle = new Library_1();
    }
}
