流程：
PDO方式连接数据库->将网站所需的数据以二维数组赋值到一个变量->在相应的位置对其数组数据遍历->页面显示
1-1 PDO连接所需参数
实例
<?php return [ 'type'=>'mysql', 'host'=>'127.0.0.1', 'dbname'=>'kuqiwang', 'username'=>'root', 'password'=>'root', ];

1-2实例化PDO
实例
<?php
$db = require __DIR__.'\data.php';
$dsn = "{$db['type']}:host={$db['host']};dbname={$db['dbname']}";
$username = $db['username'];
$password = $db['password'];
try{
$pdo = new PDO($dsn,$username,$password);
// echo'连接成功';
}catch(PDOException $e){
die('连接失败'.$e->getMessage());

1-3获取数据表数据
