How to connect PHP with MySQL database?

<?php
$servername = "localhost"; // or your database server IP
$username = "your_username"; // your database username
$password = "your_password"; // your database password
$dbname = "your_database"; // your database name
 // Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
 // Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
 // Close connection
$conn->close();
?>

Explanation:

• Replace your_username, your_password, and your_database with your actual database credentials.
• This code uses mysqli extension to connect to the MySQL database.
• Always handle errors properly and consider using prepared statements for security.
