I am searching for a simple solution to call a PHP function only when a-tag is clicked.
PHP:
function removeday() { }HTML:
<a href="" onclick="removeday()" class="deletebtn">Delete</a>UPDATE: the html and PHP code are in the same PHP file

First, understand that you have three languages working together:
PHP: It only runs by the server and responds to requests like clicking on a link (GET) or submitting a form (POST).
HTML & JavaScript: It only runs in someone’s browser (excluding NodeJS).
I’m assuming your file looks something like:
<!DOCTYPE HTML><html><?php function runMyFunction() { echo 'I just ran a php function'; } if (isset($_GET['hello'])) { runMyFunction(); }?>Hello there!<a href='index.php?hello=true'>Run PHP Function</a></html>Because PHP only responds to requests (GET, POST, PUT, PATCH, and DELETE via $_REQUEST), this is how you have to run a PHP function even though they’re in the same file. This gives you a level of security, “Should I run this script for this user or not?”.
If you don’t want to refresh the page, you can make a request to PHP without refreshing via a method called Asynchronous JavaScript and XML (AJAX).
That is something you can look up on YouTube though. Just search “jquery ajax”
I recommend Laravel to anyone new to start off right: http://laravel.com/
