Overview Magento 2 get currency data

Step 1: Declare in Mageplaza_HelloWorld

You will use a block class of the module Mageplaza_HelloWorld, then possibly inject the object of StoreManagerInterface & Currency class in the constructor of the module’s block class.

app/code/Mageplaza/HelloWorld/Block/HelloWorld.php

<?php
namespace Chapagain\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
    protected $_storeManager;
    protected $_currency;
    
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,        
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Directory\Model\Currency $currency,        
        array $data = []
    )
    {        
        $this->_storeManager = $storeManager;
        $this->_currency = $currency;        
        parent::__construct($context, $data);
    }
    
        
    /**
     * Get store base currency code
     *
     * @return string
     */
    public function getBaseCurrencyCode()
    {
        return $this->_storeManager->getStore()->getBaseCurrencyCode();
    }
    
     /**
     * Get current store currency code
     *
     * @return string
     */
    public function getCurrentCurrencyCode()
    {
        return $this->_storeManager->getStore()->getCurrentCurrencyCode();
    }    
    
    /**
     * Get default store currency code
     *
     * @return string
     */
    public function getDefaultCurrencyCode()
    {
        return $this->_storeManager->getStore()->getDefaultCurrencyCode();
    }
    
    /**
     * Get allowed store currency codes
     *
     * If base currency is not allowed in current website config scope,
     * then it can be disabled with $skipBaseNotAllowed
     *
     * @param bool $skipBaseNotAllowed
     * @return array
     */
    public function getAvailableCurrencyCodes($skipBaseNotAllowed = false)
    {
        return $this->_storeManager->getStore()->getAvailableCurrencyCodes($skipBaseNotAllowed);
    }
    
    /**
     * Get array of installed currencies for the scope
     *
     * @return array
     */
    public function getAllowedCurrencies()
    {
        return $this->_storeManager->getStore()->getAllowedCurrencies();
    }
    
    /**
     * Get current currency rate
     *
     * @return float
     */
    public function getCurrentCurrencyRate()
    {
        return $this->_storeManager->getStore()->getCurrentCurrencyRate();
    }
    
    /**
     * Get currency symbol for current locale and currency code
     *
     * @return string
     */    
    public function getCurrentCurrencySymbol()
    {
        return $this->_currency->getCurrencySymbol();
    }    
}
?>

You can see more functions in vendor/magento/module-store/Model/Store.php and vendor/magento/module-directory/Model/Currency.php.

Step 2: Get the output of the currency data in phtml file

Allow getting and printing the currency rate, currency code, and currency symbol when you run the below command in the template phtml file.

echo $block->getCurrentCurrencySymbol() . '<br />';
echo $block->getCurrentCurrencyCode() . '<br />';
echo $block->getBaseCurrencyCode() . '<br />';
echo $block->getDefaultCurrencyCode() . '<br />';
echo $block->getCurrentCurrencyRate() . '<br />';
 
print_r($block->getAvailableCurrencyCodes()) . '<br />';
print_r($block->getAllowedCurrencies()) . '<br />';
