How to Execute PHP Functions Using Onclick Events without Page Refreshes?

Execute PHP Functions Using Onclick Events

Incorporating PHP functions within onclick events can prove a bit challenging. To gain a deeper understanding, it's crucial to remember that PHP functions are executed on the server-side, while HTML and JavaScript operate within the client-side browser.

Procedure:

Identify that three languages are interacting: PHP, HTML, and JavaScript.
Understand that PHP responds to server requests (such as clicking links or submitting forms), while HTML and JavaScript run in the user's browser.
Assuming your HTML and PHP code reside within the same PHP file, it may resemble the following:

<code class="html"><!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></code>

Copy after login

Since PHP relies on server requests, executing a PHP function requires triggering a request via the URL (e.g., using index.php?hello=true).
To avoid page refreshes, consider utilizing Asynchronous JavaScript and XML (AJAX) for handling server requests without refreshing the browser.

Alternatives:

Laravel, a popular web application framework, simplifies these processes and provides an ideal starting point for beginners.
