凝聚PHP数组？

Question

你好，我有以下代码来生成我的导航/页面菜单，并将样式元素应用到活动页面。我想知道如何才能凝聚代码而不是拥有两个合并数组？

这是我目前的代码，两者之间的区别是html链接输出。 “首页”链接必须是<a href="./'. $k .'">'. $v .'</a>

而其它页面需要有<a href="./?p='. $k .'">'. $v .'</a>

<?php 

    $current = array(
    "" => "Home" 
    ); 
    foreach($current as $k => $v) { 
     $active = $_GET['p'] == $k 
     ? ' class="current_page_item"' 
     : ''; 
    echo '<li'. $active .'><a href="./'. $k .'">'. $v .'</a></li>'; 
    } 

    $current = array(
     "contact" => "Contact Us", 
     "about" => "About Us", 
     "privacy" => "Privacy Policy" 
    ); 
    foreach($current as $k => $v) { 
     $active = $_GET['p'] == $k 
      ? ' class="current_page_item"' 
      : ''; 
     echo '<li'. $active .'><a href="./?p='. $k .'">'. $v .'</a></li>'; 
    } 

?> 

任何帮助将不胜感激，谢谢:)

} 

?>

几乎相同

$ href = empty（$ k）？ “./”：“./?p={$k}”;
