XML File does not reflect changes upon reopen - HELP

if ($isValid) { $cgi = '/cgi-bin'; if (strpos($HTTP_HOST, 'dyndns') === false) $cgi .= '/cgiwrap/ppowell'; $fileID = fopen("http://$SERVER_NAME$cgi/pollinsert.cgi?pollID=$pollID&answerID=$answerID&valIdentifier=" . urlencode($valIdentifier) . "&lastPollResultsID=" . ($pollResultsArray[sizeOf($pollResultsArray) - 2][attributes][ID] + 1), 'r') or die('Could not open CGI'); $result = fread($fileID, 100000); fclose($fileID); if (trim(strtoupper($result)) != 'DONE') die ("Problem with TCL CGI writing to file: $result"); // RE-PARSE XML CONTENTS SINCE ADDING NEW POLL ANSWER unset($pollResultsArray); unset($pollResultsXMLStuff); $fileID = fopen('/users/ppowell/web/xml/pollresults.xml', 'r') or die('Could not reopen file'); $pollResultsXMLStuff = fread($fileID, filesize('/users/ppowell/web/xml/pollresults.xml')); fclose($fileID); $parser = xml_parser_create(); xml_parse_into_struct($parser, $pollResultsXMLStuff, $pollResultsArray, $tags); xml_parser_free($parser); } else { // REDIRECT BACK TO POLL IF header("Location: http://$SERVER_NAME/poll/poll.php?pollID=$pollID&errorMsg=" . urlencode($errorMsg)); } // END OF FORM PLACEMENT } I am making changes to an XML file (and the only way I can, unless anyone knows how in PHP I can write TO an XML file!!! is to use a TCL CGI script to write to the XML file), once changes have been made I need to reopen the file and read its contents, however, every time I do I am getting OLD file information and NOT my changes, every single time, unless I refresh my page... Does anyone know what I can do about this? I can't redirect them, that would be horribly inefficient.. what can I do? Thanx Phil
