How can PHP be used to continuously update and display real-time sensor data on a website interface?

To continuously update and display real-time sensor data on a website interface using PHP, you can utilize AJAX to periodically fetch the latest sensor readings from the server without refreshing the entire page. You can then use JavaScript to dynamically update the sensor data on the webpage in real-time. 

<?php
// PHP code to fetch sensor data from a database or API
$sensor_data = get_sensor_data(); // Function to get sensor data

// Output sensor data as JSON
header('Content-Type: application/json');
echo json_encode($sensor_data);
?>
