Exactly!
You could also do it like this:
$tmpname = 'test.tpl.tmp.'.posix_getpid();
file_put_contents($tmpname, '....');
rename($tmpname, 'test.tpl');
That way - adding the process ID to the temporary filename - does not run into
the danger of two processes changing the file at the same time. The LOCK_EX
should handle that case, too, but I usually go for the "appended PID" approach
and don't worry about file locking at all.
