That's a lot of code in the PHP example! To use bcrypt you can just do this:

  password_hash($password, PASSWORD_BCRYPT)\n

\nFrom version 5.5 that is, but you can get a compatibility library for older versions.

This is bang on. PHP devs need to stop rolling their own hashing methods.

The compatibility library to use for PHP <5.5 is Antony Ferrara's password_compat: https://github.com/ircmaxell/password_compat.
