Writing a file can be done in a single line, with file_put_contents().
Unfortunately, file_get_contents() and file() both need 5 lines to flock() - this is more complex than it needs to be, and asymmetrical wrt file_put_contents().

$fp = fopen ($DATA_FILE,"r");
flock ($fp, LOCK_SH);
$contents = file_get_contents($DATA_FILE);  
flock ($fp, LOCK_UN);
fclose ($fp);

How is it possible that this hasn't been addressed in 6 years??

This shouldn't even be marked as a feature request, this is a bug. A bug in the specifications, but still a bug. And a huge and obvious one.
