javascript - Would linked php file using scrolling plugin make html page refresh -

Using this plugin for infinite scroll

The first row of the page is such a line Which is linked to a .php file, which every time users want to load more content

  echo ('& lt; a href = "loadmore.php" & gt; & lt; / a & gt;');  

The php code for selecting and receiving further content in the linked file. Will that PHP code refresh the page - should I use AJAX?
