How can the "mysqli No database selected" error be resolved in the PHP code snippet provided?

The "mysqli No database selected" error occurs when the PHP script tries to perform database operations without selecting a specific database. To resolve this issue, you need to add a line of code to select the database before executing any queries. This can be done using the mysqli_select_db() function. 

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "your_database_name";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Select the database
mysqli_select_db($conn, $dbname);

// Now you can execute your queries
// For example:
$sql = "SELECT * FROM your_table";
$result = $conn->query($sql);

// Rest of your code here

$conn->close();
?>
