The script language doesn't matter all that much, because the end result is to send out a page of HTML to the browser.

There are some things that are just easier to do in PHP, and there are some things (like domain canonicalisation) that are easier to do to with an out-of-the-box Apache server (compared to using IIS).

That said, the reasons for your suggested changes are complete junk. Whoever is saying that, has no idea what they are talking about.
