What are common issues when using Ratchet for a chat application in PHP?

One common issue when using Ratchet for a chat application in PHP is handling multiple connections and broadcasting messages to all connected clients. To solve this, you can use a loop to iterate through each connected client and send the message to them individually.

// Loop through each connected client and send the message
foreach ($this->clients as $client) {
    $client->send($message);
}
