What are the advantages of using variables variables in PHP to store values from a database?

Using variables in PHP to store values from a database allows for easier manipulation and reuse of the data throughout the code. This can help improve readability, reduce redundancy, and make the code more organized. Additionally, using variables can make it easier to pass data between different parts of the code or even between different pages. 

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

// Select data from database
$sql = "SELECT * FROM table";
$result = $conn->query($sql);

// Store values in variables
while($row = $result->fetch_assoc()) {
    $id = $row['id'];
    $name = $row['name'];
    $email = $row['email'];

    // Use the variables as needed
    echo "ID: " . $id . "<br>";
    echo "Name: " . $name . "<br>";
    echo "Email: " . $email . "<br>";
}

// Close the connection
$conn->close();
