static function CurrencyLocalePattern::loadFromEnv in Currency 7.2

Loads a single CurrencyLocalePattern based on environment variables.

If no country code is set in $language->currency_country_code, the "site_default_country" system variable will be used instead. If a CurrencyLocalePattern could not be loaded using these country sources and $language->language, the locale pattern for en_US will be loaded. This is consistent with Drupal's default language, which is US English.

Return value

CurrencyLocalePattern

Throws

RuntimeException

1 call to CurrencyLocalePattern::loadFromEnv()
