Yes, that would be correct.  When you enable serialize, PHP processes 
the data through the serialize() function before sending it.

Now I've never tried sending between PHP and C, so I haven't seen your 
problem.  However, some questions:

1). What OS are you using (including version)?
2). Do you have all errors being displayed?  Your php.ini file in your 
test system should have:
   error_reporting=E_ALL
   display_errors=on
3). What does the code in you C program look like?
4). What compiler did you use for the C program?

I'm sure I can come up with more :) but this is a start.

Actually - I just thought of something else.  PHP may not be adding the 
ending null character.  What happens if you send "Hi\0"?
