It looks like there's a fundamental problem of understanding how the
things work between the server and the client.

Think of an HTML page as if it would be just plain text, and in fact it
actually is - more or less. It's entirely up to the browser to do
something useful with that received text. The server couldn't care less
about what happens on the client side. All your PHP script can do is to
generate such text and send it to the browser. That's it.

This text can be plain HTML, but may also contain some more stuff like
JavaScript for example. But this is an entirely client-specific thing.
For your PHP script it's just meaningless text, a bunch of strings to
print. HTML, JavaScript etc. have no meaning in PHP, the interpreter
doesn't know about such things. There's also no direct communication
between the PHP script and the browser, so your script doesn't know what
happens on the client or how the received text will be handled. It just
creates the text - and that's it.
