I'm curious why you want this.  Locking is almost never the right 
solution for a web app.  Writing to a temp file and then atomically 
rename it into its final destination.  Adding locks to every library 
function PHP can call that can potentially write files is not feasible.

Apparently there is not way to lock files while writing to them.

I'd like to see a similar behavior like the flags in 
http://php.net/file_put_contents

Maybe the file actually get's locked. I can't test it.
