pdo 连接类? [英] pdo connection class?

问题描述

我正在尝试了解 PDO，人们说它是与数据库交互的简单和最佳方式，但我觉得这并不容易.有什么可以帮忙的吗?

I am tring to learn about PDO people have said its easy and the best way to interact with the database, but im not finding it easy. can any help?

连接.php

<?php

class Connection {
    public function dbConnect() {
        return new PDO("mysql:host=localhost; dbname=lr", "root", "");
    }
}

?>

index.php

<?php
require_once('pdo.php');
$obj = new Connection();

$obj->dbConnect();
echo 'hello';
?>

这行得通，但太简单了.什么是最好的方法?

This works but its too simple. what is the best way?

我应该在自己的类中建立连接并将其扩展到我的其他类，还是应该使用全局变量来连接?还是有另一种更好的方法?谢谢

Should i have my connection in its own class and extend it to the rest of my classes or should i use a global variable to connect? or is there another way better way? Thanks

推荐答案

您只是在创建连接，并没有告诉我们您要实现的目标.您是要发布、更新、删除数据库中的某些内容还是什么?

You are just creating a connection and not telling us what you are trying to achieve. Do you want to post, update, delete something in the database or what?

因为您什么都不问，所以我能做的最好的事情就是将您链接到一个网站，该网站将尝试教您基础知识.不过我希望你以前用过数据库.

The best I can do since you aren't asking anything is link you to a website that will try to teach you the basics. I hope you have used databases before though.
