Pragmatically speaking, this is the typical order:

PHP runs first and constructs the page.
The browser loads the resulting HTML (any JavaScript found gets executed immediately)
Any JavaScript that was tied to the DOM ready or load event gets executed once the whole HTML is read and all objects are loaded respectively.

PHP will execute first, then HTML and finally javascript.

You send request to server, server executes your script
Then returns rendered html to browser, browser parses HTML(inline javascript executed)
Finally executes external included javascript files, one by one in order they are included.
