Trigger PHP function by clicking HTML link

Question

Is it possible to trigger a PHP function by just clicking a link? Or should I stick with the form submit method? If clicking the link will work, where should the link refer

Answer 1

To trigger a function on link click with php the only way I know would be to append a param in the url of the link and then listen for that

Add my username to the list

Then check for link

if (isset($_GET['function'])){
      runFunction();
}

This is because php is a server side technology if you want to fire something without refreshing the page you would need to look at something like javascript
