使导航栏在 php include_once 标签中处于活动状态 - Make navigation bar active in php include_once tag

Make navigation bar active in php include_once tag

我在标题中拥有所有页面的基本导航栏.php那么它如何使其处于活动状态，以便人们通过导航栏知道他们在哪个页面上

.HTML

<ul class="menu">
     <li><a href="index.php">HOME</a></li>
     <li><a href="features.php">SMARTRETAIL FEATURES</a></li>
     <li><a href="faq.php">FREQUENTLY ASKED QUESTIONS</a></li>
     <li><a href="customers.php">CUSTOMERS</a></li>
     <li><a href="contactus.php">CONTACT US</a></li>
     <li><a href="userguide.php">USER GUIDE</a></li>
  </ul>

.CSS

ul.menu {
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    background-color: #333;
}
ul.menu li {
    float: left;
    border-right: 1px solid black;
}
ul.menu li a {
    display: block;
    color: white;
    text-align: center;
    padding: 14px 16px;
    text-decoration: none;
}
ul.menu li a:hover:not(.active) {
    background-color: #000000;
}
.active {
    background-color: #2676f5;
}

如果 php 参考这里的答案如何在 php 中设置当前页面"活动"

总之

// set this above the include of the nav
$activePage = "offnungszeiten.php";
$pages = array();
$pages["index.php"] = "Öffnungszeiten";
$pages["features.php"] = "Sauna";
$pages["faq.php"] = "Frauensauna";
$pages["custom.php"] = "Beauty Lounge";
$pages["feiertage.php"] = "Feiertage";

//menu.php
<?php foreach($pages as $url=>$title):?>
  <li>
       <a <?php if($url === $activePage):?>class="active"<?php endif;?> href="<?php echo $url;?>">
         <?php echo $title;?>
      </a>
  </li>
<?php endforeach;?>

试试这个：

<ul class="menu">
 <li><a href="index.php" class="<?php echo ($_SERVER['REQUEST_URI'] == '/index.php') ? 'active':'' ?>">HOME</a></li>
 <li><a href="features.php"  class="<?php echo ($_SERVER['REQUEST_URI'] == '/features.php') ? 'active':'' ?>">SMARTRETAIL FEATURES</a></li>
 <li><a href="faq.php" class="<?php echo ($_SERVER['REQUEST_URI'] == '/faq.php') ? 'active':'' ?>">FREQUENTLY ASKED QUESTIONS</a></li>
 <li><a href="customers.php" class="<?php echo ($_SERVER['REQUEST_URI'] == '/customers.php') ? 'active':'' ?>">CUSTOMERS</a></li>
 <li><a href="contactus.php" class="<?php echo ($_SERVER['REQUEST_URI'] == '/contactus.php') ? 'active':'' ?>">CONTACT US</a></li>
 <li><a href="userguide.php" class="<?php echo ($_SERVER['REQUEST_URI'] == '/userguide.php') ? 'active':'' ?>">USER GUIDE</a></li>
