What is the best way to create a ticker in PHP that displays data from a MySQL database?

To create a ticker in PHP that displays data from a MySQL database, you can use AJAX to periodically fetch data from the database and update the ticker on the webpage without refreshing the entire page. This can be achieved by creating a PHP script that connects to the database, retrieves the data, and returns it in a format that can be easily displayed on the webpage. 

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

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

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

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

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo $row["data_column"] . "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
