Hi,

Few comments...

The original F0 values in the AWB example were extracted by
ESPS's get_f0. See section "Pitch and formant extraction " in
http://www.speech.kth.se/snack/tutorial.html for details.

PDA works as well. I wasn't happy with unvoiced results in the creaky
sections in my speech data, though.
There are other F0 extractors as well, like Praat and tempo,
which may or may not be better.

You are using F0 range 80-200 in your PDA example, which are
probably reasonable values for an average male voice.
Note however that the typically HTS uses 5ms milliseconds frames,
not the 10 ms frames that are the default in PDA.
See --length option.

As for the unexpected output.
I'm lazy and not particularly good with endianisms or PHP...
I'd use something like

pda foo.wav -L -length 0.005 -fmin 80 -fmax 200 | x2x +af > foo.f0

Try whether it works for you.

(Notice also that PDA seems to print an extra space at the start of the
output.)

Good look,

  Nicholas
