php的include选项是否进行部分页面刷新？

Question

I've started using PHP locally and notice that if I use include files within a main index.php file, the whole page does not refresh when I click a button/link that will include a new/updated include file. My question is, is php's include option like ajax and only does a partial page refresh? If so, am I better off using just plain php or should I stick with ajax?

PHP code is interpreted server-side so it doesn't use AJAX like client-side JavaScript. Clicking a link will request a new page, and PHP will interpret the requested files and return the output. You're likely not experiencing refresh times because you're working locally. If you take a look at the Network tab of Chrome Developer tools you'll see the refresh take place.
