如何更改 URL 在頁(yè)面上調(diào)用的功能？下面是一個(gè)示例：https://exaplesitename.com/index.php?id=21 它現(xiàn)在的樣子，但我希望它是這樣的：https://exaplesitename.com/Entertainment 這是導(dǎo)航代碼：<?phpfunction find_parent_categories($options=[]) {    global $db;    $Active = $options['Active'] ?? 'false';    $sql = "SELECT * FROM Parent_Categories ";    if($Active){        $sql .= "WHERE Active = true ";    }    $sql .= "ORDER BY Category_Order ASC";    $result = mysqli_query($db, $sql);    confirm_result_set($result);    return $result;}function find_categories($id_Category_Parent, $options=[]){    global $db;    $Active = $options['Active'] ?? 'false';    $sql = "SELECT * FROM Categories ";    $sql .= "WHERE id_Category_Parent='" . db_escape($db, $id_Category_Parent) . "' ";    if($Active){        $sql .= "AND Active = true ";    }    $sql .= "ORDER BY Category_Order ASC";    $result = mysqli_query($db, $sql);    confirm_result_set($result);    return $result;} ?><nav class="navbar fixed-top navbar-expand-lg bg-white navbar-custom">    <a class="navbar-brand" href="<?php echo url_for('/index.php'); ?>">        <img src="../../images/Logo1.png" alt="Nantucket" class="img-fixed"/>    </a>    <button class="navbar-toggler custom-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent1" aria-controls="navbarSupportedContent1" aria-expanded="false" aria-label="Toggle navigation">Menu        <span class="navbar-toggler-icon"></span>     </button>
