I've ran into a bit of trouble trying to implement Blowfish in PHP- I've successfully ported a C implementation, and implemented a test-vector test in both languages.

The output (needs a fixed-width font) might speak for itself:

9/34 tests succeeded.

Failure number refers to the first L or R column pair that failed - they should be identical.
In the PHP test, ( ) refers to the first letter of it's gettype() result- integer or double.

Looking at this it seems PHP doesn't seem to allow that int == float, but allows to print them, and then they turn out equal.

Also, you will note the PHP and C values are very different, although the code is nearly exactly the same - I can't figure out what causes this, but since the results seem to be OK, it does not seem to matter :|

I'm not going to post my huge (20 kb) script here, but I'll send it if anyone needs to see it.
