您需要添加以下资源才能使其正常工作

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha.5/css/bootstrap.min.css" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://npmcdn.com/tether@1.2.4/dist/js/tether.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha.5/js/bootstrap.min.js"></script>

我删除了你的代码的php部分并放了一些随机的html

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha.5/css/bootstrap.min.css" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://npmcdn.com/tether@1.2.4/dist/js/tether.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha.5/js/bootstrap.min.js"></script> 
<nav class="navbar navbar-default navbar-fixed-top" role="navigation">  
            <div class="container-fluid">

                <!-- Logo & Responsive Menu -->
                <div class="navbar-header">
                    <button type="button" id="nav-toggle" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navigation-menu">Toggle navigation</button> 
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                    </button>
                </div>  <!-- End navbar-header -->

                <!-- Navigation -->

                <nav id="navigation-menu" class="collapse navbar-collapse"  role="navigation">
                  <ul class="nav navbar-nav navbar-right">
                 <li>hi</li>            

                  </ul>
                </nav>  <!-- End navbar-collapse -->

            </div>  <!-- End container -->
            <br />
        </nav>  <!-- End navbar -->
