How to use a zend framework 2 view helper in any class:

ZF2-view-helpers-in-classes.php

<?php
// This will allow you to use any view helper in any class such as a controller //
// 1. Instantiate the view helper.
// 2. Configure it.
// 3. Use it.

// E.g. Use currency formatter
$currencyFormatter = new CurrencyFormat();
$currencyFormatter->setCurrencyCode('USD');
$currencyFormatter->setLocale('en_US');

$value = 10000;

$formattedValue = $currencyFormatter($value);

var_dump($formattedValue); // Will output $ 1,000 with HTML entities such as &nbsp;

// When this example will be useful?
// In a select element of a form, as the value options are automatically echoed by the formRow view helper
// the currency format needs to be set when the value options are assigned.
