Perhaps you might want to read up on chapter 6 of the manual on Types and the list of escaped characters. 4) Erm, my knowledge of regex is pretty pitiful, I'm afraid. If all you want to do is get rid of them, you probably should use str_replace or substr_replace to replace them with a '' (null, in single quotes) something like $val = str_replace('\n','',$val); $val = str_replace('\r','',$val); might do the trick. -- David Robley | WEBMASTER & Mail List Admin RESEARCH CENTRE FOR INJURY STUDIES | http://www.nisu.flinders.edu.au/ AusEinet | http://auseinet.flinders.edu.au/ Flinders University, ADELAIDE, SOUTH AUSTRALIA
