How can using a stream in PHP help save traffic when checking a database for new entries?

Using a stream in PHP can help save traffic when checking a database for new entries by allowing us to continuously listen for changes in the database without repeatedly querying it. By setting up a stream to monitor the database, we can receive real-time updates as soon as new entries are added, reducing the need for frequent database queries and saving on unnecessary network traffic. 

<?php

$stream = fopen('database_updates.txt', 'r');

while (true) {
    $data = stream_get_contents($stream);
    
    if (!empty($data)) {
        // Process the new database entry
        echo "New entry added: " . $data . PHP_EOL;
    }
    
    sleep(1); // Check for updates every second
}

fclose($stream);
?>
