For most php applications, a 1-way hash such as md5 or sha1 is sufficient for storing passwords in a database. This is more secure, because passwords aren’t stored in plaintext and when a user does type in a password to login to the application, it is compared to a hash rather than the actual password. A problem with this method is that there is no way to get the original password. So if a user forgets their password, the only thing that you can do is reset (by generating a new one) it and send them this new password.
