数据库
1、system表：网站的配置信息
2、category表：栏目表
3、detailsList表：内容详情表
一、公共部分
database.php
连接数据库参数设置：
$dsn = '数据库的类型：host=数据库主机名; dbname=数据库名称';
<?php return[ 'type' => 'mysql', 'host' => '127.0.0.1', 'dbname' => 'php', 'username' => 'root', 'password' => '' ];
connect.php
连接数据库
<?php
// 连接数据库：PDO
$db = require 'database.php';
// $dsn = '数据库的类型：host=数据库主机名; dbname=数据库名称';
$dsn = "{$db['type']}:host={$db['host']}; dbname={$db['dbname']}";
$username = $db['username'];
$password = $db['password'];
try{
$pdo = new PDO($dsn, $username, $password);
//var_dump($pdo);
}catch (PDOException $e){
die('数据库连接失: ' . $e->getMessage());
}头部 header.php
<?php // 1、连接数据库 require __DIR__ . '/connect.php'; // 2、获取网站的配置信息 $sql = 'SELECT * FROM `system` limit 1'; $stmt = $pdo->prepare($sql); $stmt->execute(); $system = $stmt->fetch(PDO::FETCH_ASSOC); // 3、获取栏目信息 $sql = 'SELECT `cate_id`, `name`, `alias` FROM `category`'; $stmt = $pdo->prepare($sql); $stmt->execute(); $cates = $stmt->fetchAll(PDO::FETCH_ASSOC); $cate_count = count($cates); // 4、获取详细信息 $sql = 'SELECT * FROM detailsList'; $stmt = $pdo->prepare($sql); $stmt -> execute(); $detailsList = $stmt->fetchAll(PDO::FETCH_ASSOC); ?> <!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title><?php echo $system['title'] ?></title> <meta name="keywords" content="<?php echo $system['key'] ?>"> <meta name="description" content="<?php echo $system['desc'] ?>"> <link rel="stylesheet" href="./static/css/style.css"> </head> <body> <div class="header"> <ul class="nav"> <li><a href="index.php">首页</a></li> <li><a href="">***介绍</a></li> <?php foreach ($cates as $cate): ?> <li><a href="list.php?cate_id=<?php echo $cate['cate_id'] ?>"><?php echo $cate['alias'] ?></a></li> <?php endforeach; ?> </ul> </div>

<?php
// 使用双重循环来遍历两个数组
// 外层遍历栏目数组$cates，内层根据栏目id来查询对应的栏目详情 $detailsList 信息
foreach ($cates as $cate){

// 遍历栏目详情数组
foreach ($detailsList as $list){
// 判断当前栏目详情所属栏目是否与当前栏目id相同
if($list['cate_id'] === $cate['cate_id']){
