PHP更新后Codeigniter DX_Auth登录无法正常工作

Question

I recently upgraded PHP from 5.3.5 to 5.3.10. I'm using the DX_Auth authentication library for Codeigniter. Now I have the following problems:

• Users who registered after the update cannot log in
• Users who changed their password after the update cannot log in anymore

Users who created an account before the update can still log in. DX_Auth uses PHPs crypt() function.

Any ideas what's going on here?

Answer 1

Apparently DX_Auth generates longer hashes after the PHP update. Increasing the length of the password field in the DB did the trick.
