I've seen answers both ways in the archive of this list, and I wonder what is true.
Suppose I open a file in append mode - like a log file. Two different HTTP connections fire up two different PHP processes which both open the same file. Then they both do an fwrite( $fp, "some string" ). Is the result serializable? That is, is one write guaranteed to be appended after the the other? Or is there a chance that one will overwrite the other and truncate the file - in which case, I'll need an flock() even for the simplest log file. What if I opened the file in some other mode, like "w" or "r+"?
