problems with socket

Hi I hope someone can help me I have made a program with a servercomponent And this program connects to a PHP script on a webserver and the script makes a socket connection to this servercomponent and I want that this script logs into a database (or whatever) the logintime and when the program disconnects it works fine but if my internetconnection interrupts (for example my provider makes a IP change) the script doesn't recognize it .... what can I do?? my script: $fp = fsockopen($ip, $port, &$err_num, &$err_msg, 10); if ($fp) { $daten = "GET / HTTP/1.0\r\nUser-Agent: TestClient\r\n\r\n"; fputs($fp, $daten); // Database Entry >ONLINE!< while (!feof($fp)) { $zwdaten .= fgets($fp, 1); } // Database Entry >OFFLINE!< } MFG Günther Leitgeb webmaster@gleitgeb.at webmaster@gl5funk.cjb.net webmaster@gl-webradio.cjb.net webmaster@gl-netradio.cjb.net ICQ: 104677570
