Magento Store Credit Extension Simple Example

<?php
// Loads a blank page and displays something like "This customer's store credit balance is $150.25"
// If you don't already have the Magecredit Magento extension you can get it at www.magecredit.com

require_once('app/Mage.php'); //Path to Magento
umask(0);
Mage::app();

// The next line loads the magecredit customer balance model.
$_balance = Mage::getModel('wf_customerbalance/balance')
            ->setCustomerId(136) // change this to whatever your customer ID is.
            ->loadByCustomer();

// This line formats the amount using the currently loaded store's currency
$_amount = Mage::app()->getStore()->formatPrice( $_balance->getAmount() );

// Example Output: This customer's store credit balance is $150.25
echo Mage::helper('core')->__('This customer\'s store credit balance is %s', $_amount);
