I think the default crypt in PHP is the Unix DES crypt. You could prefix
your hash with {crypt}.

Hmm, I suggest you should take a look at the different hashing and
encryption options in the reference manual ref.pdf. See sections 13.1.1
and 13.1.2 for User-Password and Encrypted-Password check items. You may
find the suitable {prefix} from there if your PHP crypt does something
else than Unix DES crypt.
If you want to pass the password to MySQL function, use %P to get
decoded User-Password.
