What are some potential pitfalls to be aware of when using UDP connections in PHP?

One potential pitfall when using UDP connections in PHP is the lack of error checking and handling. Since UDP is connectionless and unreliable, there is no guarantee that data will be successfully transmitted or received. To address this, it is important to implement error handling mechanisms to ensure that data is properly sent and received. 

// Create a UDP socket
$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);

// Send data
if (socket_sendto($socket, $data, strlen($data), 0, $address, $port) === false) {
    echo "Error sending data: " . socket_strerror(socket_last_error());
}

// Receive data
if (socket_recvfrom($socket, $data, $length, 0, $address, $port) === false) {
    echo "Error receiving data: " . socket_strerror(socket_last_error());
}

// Close the socket
socket_close($socket);
