I think you may be gradually going down the wrong path because you are
asking very narrow questions.  This is made worse by the fact that your
questions are not very clear so people are just suggesting thing you
might try rather than guiding you to the best solution.

I suggest you back up a bit.  What are you doing overall?  What is it
you are trying to do that has led you to think that a file control, some
client side script and a bit of PHP is the solution?
