HI If you are using MySql look at ENCODE() on mysql.com
http://www.mysql.com/doc/M/i/Miscellaneous_functions.html Most databases support some sort of encryption. Encrypting by php is probably more secure - somebody might be able to sniff data going to the database if it still plain text, but that is a small risk IMHO, and getting the database to do it is easy .
