Socket_strerror (Socket_last_error ()). "\ n";} else {echo "ok.\n";} echo "Attempting to connect to ' $address ' on port ' $service _port ' ..."; $result = Socket_connect ($socket, $address, $service _port), if ($result = = = False) {echo "Socket_connect () Failed.\nreason: ($result)". Socket_strerror (Socket_last_error ($socket)). "\ n";} else {echo "ok.\n";} $in = "head/http/1.1\r\n"; $in. = "host:www.example.com\r\n"; $in. = "connection:close\r\n\r\n"; $out = "; echo" sending HTTP HEAD request ... "; Socket_write ($socket, $in, strlen ($in)); echo" ok.\n "; echo" Reading response:\n\n "; $buf = ' This is M Y buffer. '; if (false!== ($bytes = Socket_recv ($socket, $buf, 2048, MSg_waitall)) {echo "Read $bytes bytes from Socket_recv (). Closing socket ... ";} else {echo "socket_recv () failed; Reason: ". Socket_strerror (Socket_last_error ($socket)). "\ n";} Socket_close ($socket); Echo $buf. "\ n"; echo "ok.\n\n";?  >
