How can a PHP query be used to retrieve only new entries from the last hour?

To retrieve only new entries from the last hour using a PHP query, you can use the `NOW()` function in MySQL to get the current timestamp and then subtract an hour to get the timestamp from an hour ago. You can then use this timestamp in your query to filter out entries that were created before the last hour. 

// Get the timestamp from an hour ago
$timestamp = date('Y-m-d H:i:s', strtotime('-1 hour'));

// Execute the query to retrieve only new entries from the last hour
$query = "SELECT * FROM your_table WHERE created_at >= '$timestamp'";
$result = mysqli_query($connection, $query);

// Process the results
while ($row = mysqli_fetch_assoc($result)) {
    // Handle each row as needed
}
