How do you connect to a MySQL database using PHP? Can you provide an example?

To connect to a MySQL database in PHP, you use the mysqli_connect function. Here's a simple example:

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

$conn = mysqli_connect($servername, $username, $password, $dbname);

if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>
