fwrite()

I'm trying to take the contents of a table and write them to a file on my server. Everything seems to function ok (AKA no errors) but no file gets written ... I can't figure out why. Can anyone shine some light on this dark problem? $db = mysql_connect("localhost","cloft","spring"); mysql_select_db("countryloft"); // get requests from table $result = mysql_query("SELECT * FROM catalogreq WHERE PROCESSED IS NULL"); $fp = fopen("$DOCUMENT_ROOT/catalogreq/catalogs.txt","w"); fwrite($fp, $result); fclose($fp); $updatereq = mysql_query("UPDATE catalogreq SET PROCESSED = 'Y'"); echo "Thank you!"; Thanks for any help!
