为什么我的php没有连接到我的服务器？

Question

I'm trying to take and get data from a database to a website using php. When I'm trying to connect I'm using this code:

<?php
error_reporting(-1);
ini_set('display_errors', 'On');
$db_host = 'localhost';
$db_user = 'root';
$db_pass = '';
$db_name = 'test';
$conn = new mysqli($db_host, $db_user, $db_pass, $db_name);
if ($conn->connect_errno) echo "failed to connect to database";
?>

but upon trying to open the php file I recieve this on firefox:

connect_errno) echo "failed to connect to database"; ?> (on firefox)

and this on opera/chrome:

<?php
error_reporting(-1);
ini_set('display_errors', 'On');
$db_host = 'localhost';
$db_user = 'root';
$db_pass = '';
$db_name = 'test';
$conn = new mysqli($db_host, $db_user, $db_pass, $db_name);
if ($conn->connect_errno) echo "failed to connect to database";
?> 

I have also tried loading it with internet explorer but it simply tries to save it again. I'm not understanding what I am doing wrong.

For extra detail I am trying to do this through xampp using phpmyadmin.

Okay, I fixed it just incase anyone looks back at this essentially the issue was my misunderstanding of the instruction 'open the php'. I was opening it directly to the browser, I needed to open it via localhost. so localhost/connect.php rather than just opening connect.php to the browser.

Answer 1

1) Make sure the extension of file is ".php"

2) Make sure that you are running page from "http://localhost//" or your local host ip.

You can test your apache/xampp by visiting "localhost" or "localhost:8080" if it is running on 8080 port.
