I have two processes running on the same server, one is creating a file,
loading it with data, and this process runs real slow.



The second process processes a directory, finds the new file and begins
reading the file contents.



How do I make the reading process detect that the file is still being filled
with data in PHP?

But you remain to be carefull, because flock is more like a semaphore
: it doesn't really lock the file. See man page for flock. (Maybe under
MS Windows the lock is hard).
