Here is some code notes:
[configs/application.ini]
resources.locale.default = en_US
[index/index.phtml]
<?php
echo '<br>HTTP_ACCEPT_LANGUAGE: ' . Zend_Controller_Front::getInstance()>getRequest()>getServer('HTTP_ACCEPT_LANGUAGE');
$locale = Zend_Registry::get('Zend_Locale');
$defaultLocale = $locale->getDefault();
foreach ($defaultLocale as $key => $value)
{
echo '<br>Default locale: ' . $key . ' (' . $value. ')';
}
echo '<br>Language: ' . $locale->getLanguage();
echo '<br>Region: ' . $locale->getRegion();
?>
[output with Zend version of Locale resource's getLocale()]
HTTP_ACCEPT_LANGUAGE: de-de,en-us;q=0.7,en;q=0.3
Default locale: en_US (1)
Language: en
Region: US
(Notice that even though the preferred language in HTTP_ACCEPT_LANGUAGE is "de-DE",
the language set in the Locale is "en_US". This is because the existing Locale
resource sets the locale language to the default setting, instead of allowing it
to detect the language using Zend_Locale automatic locale discovery)
[output using getLocale() based on code in the above comment]
HTTP_ACCEPT_LANGUAGE: de-de,en-us;q=0.7,en;q=0.3
Default locale: en_US (1)
Language: de
Region: DE
(Notice that the Locale created by the modified Locale resource is correctly set
to "de_DE" because the locale is being created using automatic locale discovery.
Automatic locale discovery ($locale = new Zend_Locale()
will detect the locale
by first looking at HTTP_ACCEPT_LANGUAGE. If automatic discovery fails, it will
ultimately use the locale default.)
When the application.ini file sets a default (fall-back) locale, Zend_Application_Resource_Locale incorrectly creates the locale object with it. This default should be set before creating the locale object and then create the object using automatic locale discovery.
For instance, the getLocale() function should be modified similar to this:
public function getLocale()
{
// Zend version incorrectly ignores HTTP_ACCEPT_LANGUAGE value when create locale object
if (null === $this->_locale) {
$options = $this->getOptions();
if (isset($options['default'])) { // Set the fall-back locale Zend_Locale::setDefault($options['default']); } else { // Should the web server's locale be set as a default when none provided? }
// Now create the locale with automatic locale discovery enabled (the default method)
$this->_locale = new Zend_Locale();
$key = (isset($options['registry_key']) && !is_numeric($options['registry_key']))
? $options['registry_key']
: self::DEFAULT_REGISTRY_KEY;
Zend_Registry::set($key, $this->_locale);
}
return $this->_locale;
}
