Thing to remember is, if the HTML page has been downloaded to the web
browser, PHP is no longer running your script. If you want to do any client
processing (such as onclick events), you need to POST a data form back to
the PHP script and process it, or send a GET request to another script. I'd
say JavaScript is what you need to control what's on the page after it has
loaded.

PHP is server-side, not client-side. It sends a page 'as is', and can only
perform actions on the server itself. It doesn't care you have set it in
an 'onclick' HTML attribute, it could care less by what random content it
is surrounded. It builds a page and sends the result to the user.

You probably want javascript for this, something that does run on the
client's computer.
