本系统代码简单，完整无BUB，完全开源，可二次开发修改并扩展。适合有志于PHP学习的同学参考学习使用，可修改为在线商城管理系统。可以写论文。

一、前端架构

前端基于bootstrap4.3框架，自适应移动端，是学习自适应移动端开发的优秀参考网站，代码干净整洁，无冗余。

<!-- Navigation -->
  <nav class="navbar navbar-expand-lg navbar-dark bg-dark">
    <div class="container">
      <a class="navbar-brand wow fadeInLeftBig" href="index.html"><img src="images/logo.png" class="img-fluid"></a>
      <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      </button>
      <div class="collapse navbar-collapse wow fadeInRightBig" id="navbarResponsive">
        <ul class="navbar-nav ml-auto">
      <li class="nav-item">
            <a class="nav-link" href="index.php">网站首页</a>
          </li>
                    <li class="nav-item">
            <a class="nav-link" href="about.php?id=53" >普洱介绍</a>
          </li>

                    <li class="nav-item">
            <a class="nav-link" href="list.php?id=57" >普洱美食</a>
          </li>

                    <li class="nav-item">

          </li>

                    <li class="nav-item">
            <a class="nav-link" href="product.php?id=6" >风景名胜</a>
          </li>

                    <li class="nav-item">
            <a class="nav-link" href="about.php?id=59" >民俗文化</a>
          </li>

                          <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="home.php" id="navbarDropdownUser" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><i class="fa fa-user-circle-o"></i>会员中心</a>
             <div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdownUser">
              <a class="dropdown-item" href="login.php">会员登录</a>
              <a class="dropdown-item" href="reg.php">会员注册</a>
            </div>
          </li>
                  </ul>
      </div>
    </div>
  </nav>

二、前端效果

首页效果

登录界面

景点展示介绍与下单界面

会员中心界面

三、后台管理功能

后台定单管理功能

后台分类管理功能

后台景点添加管理功能

四、后台部分核心代码

function Nav_next_back_html($filename, $id, $classid, $tablename){
  $pdo = new PDO(DB_DSN,DB_USER,DB_PWD,
    [PDO::ATTR_ERRMODE=>PDO::ERRMODE_WARNING]);
    $Nav_next_back_html_str = '';
    $sqlPrev = 'SELECT `id`,`title`,`class_id` FROM `'.$tablename.'` WHERE id<'.$id.' AND class_id='.$classid.' ORDER BY id DESC LIMIT 1';
  $fstmt = $pdo->prepare($sqlPrev);
  $fstmt->execute();
  if (!empty($fstmt->rowCount())) {
    $flist = $fstmt->fetchAll();
    $Nav_next_back_html_str .= '<div class="prev">上一条：<a href="'.$filename.'.php?id='.$flist[0][0].'">'.$flist[0][1].'</a></div>';
  } else {
    $Nav_next_back_html_str .= '<div class="prev">上一条：<span>暂时没有上一条内容了！</span></div>';
    
  }

  $sqlNext = 'SELECT `id`,`title`,`class_id` FROM `'.$tablename.'` WHERE id>'.$id.' AND class_id='.$classid.' ORDER BY id ASC LIMIT 1';
  $fstmt = $pdo->prepare($sqlNext);
  $fstmt->execute();
  if (!empty($fstmt->rowCount())) {
    $flist = $fstmt->fetchAll();
    $Nav_next_back_html_str .= '<div class="prev">下一条：<a href="'.$filename.'.php?id='.$flist[0][0].'">'.$flist[0][1].'</a></div>';
  } else {
    $Nav_next_back_html_str .= '<div class="prev">下一条：<span>暂时没有下一条内容了！</span></div>';
    
  }
  
  return $Nav_next_back_html_str;

}

// 获取IP函数
function GetIP(){
  if(!empty($_SERVER["HTTP_CLIENT_IP"])){
    $cip = $_SERVER["HTTP_CLIENT_IP"];
  }
  elseif(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])){
    $cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
  }
  elseif(!empty($_SERVER["REMOTE_ADDR"])){
    $cip = $_SERVER["REMOTE_ADDR"];
  }
  else{
    $cip = "无法获取！";
  }
  return $cip;
}
//echo GetIP();

// 获取父ID函数
function getParentID($cate, $id) {
    $arr = array();
    foreach ($cate as $v) {
        if ($v['id'] == $id) {
            $arr[] = $v;
            $arr = array_merge(getParentID($cate, $v['parent_id']), $arr);
        }
    }
    return $arr;
}
