The function password_verify() uses constant time. This makes it safe against timing attacks.
Don't use crypt($password_database) === crypt($password_given_by_login), since there is no
protection against timing attacks!
If you don't want to use password_verify(), then have a look at hash_equals(), which also runs
a timing attack safe string comparison.
