How can the communication between a client and a PHP daemon be efficiently managed without using a cron job?

The communication between a client and a PHP daemon can be efficiently managed using a combination of long-polling and websockets. This allows for real-time communication without the need for a cron job to periodically check for updates. 

// Client side code using long-polling to check for updates
function checkForUpdates() {
    // Make an AJAX request to the server to check for updates
    // If there are updates, process them and display to the user
    // Set up a new long-polling request after processing the updates
}

// Server side code using websockets to push updates to clients
// Implement a websocket server in PHP to push updates to connected clients
// When there are updates, send them to all connected clients
// Clients will receive the updates in real-time without the need for polling
