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"?
