用SQL和PHP连接到数据库[关闭]

Question

I'm making a website that uses SQL and PHP functionalities. How do I connect to a database?

Answer 1

The easiest way that I do with my site is make a file called db.php containing:

<?php
$host = 'localhost';
$user = 'root';
$pass = 'password';
$db = 'databasename';
$mysqli = new mysqli($host,$user,$pass,$db) or die($mysqli->error);

..then in the index.php file, at the top:

<?php
require_once('db.php')
?>
