Get function/value from php file in .phtml

Question

I'm trying to do something similar to this:

include/require php file within phtml template file

I have a .phtml file but need to get the return value from another php file by calling it from said .phtml file. How can this be achieved in Magento 2?

I tried using require, include and require_once with the path relative to the location of the .phtml file but this doesn't work (returns 500 error on page).

To make things somewhat clearer (I'm using a custom module):

• I have a Settings.php file in a folder called Helper (folder located in root of custom module, so Vendor/Module/Helper)
• Following, I have a template.phtml file under view/frontend/templates
• I want to get the return value from a function in Settings.php

Answer 1

You can call helper in .phtml like,

$helper = $this->helper('YOURNAMESPACE\YOURMODULENAME\Helper\Settings');

Now If you have some function in Settings.php then you can call like,

$helper->getSomethingFromSetting();
