There is no point in gaining an exclusive lock if you release it before flushing output. <?php $fp = fopen("/tmp/lock.txt", "r+"); if (flock($fp, LOCK_EX)) { // do an exclusive lock ftruncate($fp, 0); // truncate file fwrite($fp, "Write something here\n"); fflush($fp); // flush output before releasing lock flock($fp, LOCK_UN); // release the lock } else { echo "Couldn't get the lock!"; } fclose($fp); ?> Actual result: -------------- Saw a corrupted file that seems to indicate that output is not automatically flushed when an exclusive lock is released. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61436&edit=1
