Are there any best practices for handling UDP communication in PHP?

When handling UDP communication in PHP, it is important to set appropriate socket options, such as SO_BROADCAST, and handle errors properly to ensure reliable communication. Additionally, using non-blocking sockets can help improve performance when dealing with multiple UDP packets.

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

// Set socket options
socket_set_option($socket, SOL_SOCKET, SO_BROADCAST, 1);

// Bind the socket to a specific address and port
socket_bind($socket, '0.0.0.0', 1234);

// Receive data from a UDP client
$from = '';
$port = 0;
socket_recvfrom($socket, $data, 1024, 0, $from, $port);

// Handle the received data
echo "Received data from $from:$port - $data\n";

// Close the socket
socket_close($socket);
