The programmatic method to call helper function in phtml in Magento 2 as given below can be helpful to implement custom functionalities and enhance the store features!

Method to Call Helper Function in phtml in Magento 2:

1. Call directly helper class

    $helper = $this->helper([Vendor]\[Module]\Helper\Data);
    $values = $helper->HelperMethod();

2. Using block class

<?php 

namespace [Vendoe]\[Module]\Block;

class BlockName extends \Magento\Framework\View\Element\Template
{
     protected $helper;

     public function __construct(
     ....
    [Vendor]\[Module]\Helper\Data $helperData,
    ....
) {
    ....
    $this->helper = $helperData;
    ....
}

public function yourMethod()
{
    return $this->helper->methodName();
}

}

If you want to call block in template file like display.phtml, write $block->yourMethod(); Here, BlockName class is block that renders the template display.phtml file.

That’s it.
