If you’re running an eCommerce website using Lemonstand V1 (which is now unsupported since their V2 is the new hot stuff) and have recently upgraded your server to PHP 5.5+, you may run into a deprecated error when using Braintree Payments.

The error is in /modules/shop/payment_types/shop_braintree_transpredirect_payment/Braintree/Util.php and is pretty easy to fix.

There are two functions using the deprecated /e modifier: delimiterToCamelCase & camelCaseToDelimiter.

The fixed versions of these methods are:

delimiterToCamelCase

public static function delimiterToCamelCase($string, $delimiter = '[\-\_]')
{
    return preg_replace_callback('/' . $delimiter . '(\w)/',function($matches)   {
        return strtoupper($matches[1]);
    },$string);
}

camelCaseToDelimiter

public static function camelCaseToDelimiter($string, $delimiter = '-')
{
     return preg_replace_callback('/([A-Z])/',function($matches) use ($delimiter)  {
        return $delimiter.strtolower($matches[1]);
    },$string);
}
