Ask about this in comp.lang.javascript, mentioning 'executing code
retrieved by XMLHTTPRequest'.
Short answer: inline code will execute on a pageload, after the page has
loaded you can add all the inline code with js you want, it won't fire
unless explicitly called by some script already running or scheduled to
run. This had nothing with the fact wether or not this is done by PHP, or
just a static HTML page retrieving a static HTML snippet.
