About Whmcs Hooks

[Msonliy]

Hello !

I am a new php developer and I have a question. I'm developing a WHMCS Theme. But I'm new to PHP and I know the basics of Whmcs.

 For example, I want to get the following output somewhere I want in my custom theme. I don't know how to do this. How can I get the codes I wrote with Hooks into the html field I want?

I really need the help of a helpful person.

Thanks...

<?php

add_hook('ClientAreaPage', 1, function($vars) {

   print_r($vars['announcements']);

});
