Okay,
I better understand. What everyone is saying is php merely outputs plain text strings which can be HTML or Javascript or whatever. I write the code in
php, send it to the server, and PHP outputs a a string that the browser can
interpret( whether it interprets it to be javascript or html ).

When I say mix php and javascript, I don't mean mix literally I mean
writing code that has php and javascript syntax intertwined ( at least to the eyeye ) . I now understand that php just sees it as a string, period. The server interprets the code, and outputs something it feels the browser can read.

I'm still working with this.

Just goes to show that you can code a lot but still not really understand the concept.
