PHP and MySQL connections to server

1. Prerequisites:

  • Web server: A web server such as Apache or Nginx is required to execute PHP code.
  • MySQL server: Install and configure MySQL server.
  • MySQL credentials: Keep the database username, password, and hostname readily available.

2. Connection Script

Create a PHP file (e.g., connect.php) with the following code:


// Database credentials
$hostname = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database_name";

// Create connection

$conn = new mysqli($hostname, $username, $password, $dbname);
