Cannot connect to the MySQL database

Question

This is my config.php file which I am using for the database connection. I am using WAMP server for the database and table creation. My database name is project and I have customer_info table on it. I don't know what to write in the password column as there is no mention of password in phpmyadmin.

<?php
define("MYSQLUSER","customer_info");
define("MYSQLPASS","Password1");
define("HOSTNAME","localhost");
define("MYSQLDB","project");
function db_connect(){
$conn = @new mysqli(HOSTNAME,MYSQLDB);
if($conn -> connect_error) {
die('Connect Error: ' . $conn -> connect_error);
}return $conn;
} 
?>

Answer 1

$conn = new mysqli('localhost', 'my_user', 'my_password', 'my_db');

the object creation should be like this. You are using wrong parameters sequence.

Answer 2

You have configured your database on MySql server and you are accessing it via PHPMyAdmin (just to help you with terminology). Your config file should be edited this way:

<?php
define("MYSQLUSER","root");
define("MYSQLPASS","");
define("HOSTNAME","localhost");
define("MYSQLDB","project");
function db_connect(){
$conn = @new mysqli(HOSTNAME,MYSQLDB);
if($conn -> connect_error) {
die('Connect Error: ' . $conn -> connect_error);
}return $conn;
} 
?>
