How can a dynamic feature like a live ticker or automatic updating table be incorporated into a PHP-based CMS for website functionality?

To incorporate a dynamic feature like a live ticker or automatic updating table into a PHP-based CMS, you can use AJAX to periodically fetch new data from the server without reloading the entire page. This allows for real-time updates without disrupting the user experience.

```php
// PHP code to fetch data from the server and update the content dynamically

// This example demonstrates fetching new data from a database every 5 seconds and updating the content on the webpage

// 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);
}

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

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "<tr><td>" . $row["id"]. "</td><td>" . $row["name"]. "</td></tr>";
    }
} else {
    echo "0 results";
}

$conn->close();
```

This code snippet demonstrates how to fetch data from a database using PHP and display it on a webpage. To make it dynamic, you can use JavaScript and AJAX to periodically call this PHP script and update the content on the webpage without refreshing the entire page.
