What are the potential challenges of using a central server to relay data between clients in a PHP application?

One potential challenge of using a central server to relay data between clients in a PHP application is the risk of overloading the server with too many requests. To solve this issue, you can implement a queuing system that prioritizes and processes requests in an orderly fashion. 

// Implementing a queuing system to handle requests in a PHP application

// Check if there are any pending requests in the queue
if ($queue->hasPendingRequests()) {
    // Process the next request in the queue
    $request = $queue->getNextRequest();
    $response = processRequest($request);
    sendResponse($response);
}

// Function to process a request
function processRequest($request) {
    // Process the request and return a response
    return $response;
}

// Function to send a response back to the client
function sendResponse($response) {
    // Send the response back to the client
}
