"'\n"; /* Take a peek at the normal in-band data, but don't comsume it. */ echo "Data: '" . stream_socket_recvfrom($socket, 1500, STREAM_PEEK) . "'\n"; /* Get the exact same packet again, but remove it from the buffer this time. */ echo "Data: '" . stream_socket_recvfrom($socket, 1500) . "'\n"; /* Close it up */ fclose($socket); fclose($server); ?>
