18.18.1. Problem

18.18.2. Solution

fwrite($fh,'There are twelve pumpkins in my house.');
fflush($fh);

This ensures that "There are twelve pumpkins in my house." is written to $fh.

18.18.3. Discussion

To be more efficient, system I/O libraries generally don't write something to a file when you tell them to. Instead, they batch the writes together in a buffer and save all of them to disk at the same time. Using fflush( ) forces anything pending in the write buffer to be actually written to disk.
