压缩PHP数组？

Question

您好我有以下代码来生成导航/页面菜单以及将样式元素应用于活动页面。我想知道如何缩小代码而不是使用两个合并数组？

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

而其他页面需要<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>';
    }

?>

非常感谢任何帮助，谢谢：）

差不多

$ href =空（$ k）？ “./”：“。/？p = {$ k}”;
