What are the best practices for structuring PHP scripts to ensure that database changes are reflected immediately in the user interface?

To ensure that database changes are reflected immediately in the user interface, you should use PHP to query the database and fetch the updated data whenever the page is loaded or refreshed. This way, any changes made in the database will be displayed to the user in real-time. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// Query the database for updated data
$sql = "SELECT * FROM users";
$result = $conn->query($sql);

// Display the updated data in the user interface
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
