how to use md5() and crypt() together in php and msyql

Question

I want to use md5() and crypt() together in php login authentication.

I tried to use md5(crypt(string),salt); but i can't login in mysql.

Does anyone know how to use them together? Thanks a lot.

You've got the salt in the wrong function for a start:

md5(crypt(string,salt));

Also, assuming string and salt are variables you will need to prefix them with $:

md5(crypt($string,$salt));
