Maybe in your opinion you have. But you have given us no idea about how
you're going about the problem or a lot of other things.

If you had given enough information, we could help you.

And BTW - in PHP there is no such thing as "private" code. Once you
give it to a customer the source is available, unless you get one of the
encryption engines, i.e. from Zend.

And I don't appreciate people arguing that they have provided enough
information when they are asking for help.

I have no insecurities, and my ego isn't a problem. But obviously yours
are.

I don't need to be "imaginative". I can come up with at least a half
dozen ways to do what your description says you're doing.

I need to see the code YOU are using.

If you want help here, you need to get rid of the attitude and post
something which SHOWS the problem.

Now we're getting someplace - and this is MUCH DIFFERENT than your
original problem. The fact it works on one server but not another is
something you never mentioned before, for instance.

For one thing, you don't have all errors enabled - or you would have
seen that your first line is wrong. It should be:

define('FILE_NAME', "somefile.txt");

Now some other questions:

What versions of PHP are the two systems using?
What OS are they using?
What directory are you writing the file to?
Do you have permission to flock() the file?

Once I corrected the above problem your code works on two different systems.
