preload pages

[casak]

If the user is on page1.php and clicks on a link that loads to page2.php....is it
possible to have a loading gif or something....the next page2 is loaded and then the browser instantly changes the view from page1.php to page2.php.
In short, visually eliminating the page loading process.

Yes. That's the main idea behind technologies like Angular.js.

It's not really a server-side (e.g., in this case, PHP) thing. There is always the possibility that the server won't respond instantly. Although, one might ask, why is page2.php so slow in the first place?

Yeah, it's typically handled on the client side, not the server. If you google something like "JavaScript preload images", you should find lots of info.
