I hope you read Jerry's response - all that the PHP script knows is that
it is running and has access to certain variables. It will have been
invoked by apache or similar.
None of my PHP scripts in these circumstances do anything with web
pages. They take the data they are given, process it one way or another,
and write output (not, in my case, HTML or even XML) to stdout (I use
echo for this). This output is captured by apache (or similar) and
returned to the browser, where JavaScript may be used to examine those
results and decide how to update the page.
As all your posts appear to be hundreds of words long, and I can't be
arsed to read all that, I'm not sure I even know what you are asking.
