How can the logic of a PHP script be adjusted to display the correct values from the database without manual intervention like refreshing the page?

To display the correct values from the database without manual intervention like refreshing the page, you can use AJAX to make asynchronous requests to the server and update the content dynamically. This way, the PHP script can fetch the latest data from the database without requiring the user to manually refresh the page. 

// PHP script to fetch data from the database
<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";

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

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

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

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Value: " . $row["column_name"] . "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
