What are some common issues when trying to send datagrams using PHP and how can they be resolved?

Issue: One common issue when sending datagrams using PHP is not setting the correct socket type when creating the socket. To resolve this, make sure to specify the correct socket type (SOCK_DGRAM) when creating the socket. 

// Create a UDP socket
$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
if (!$socket) {
    echo "Error creating socket: " . socket_strerror(socket_last_error());
    exit;
}
