Example #1 locale_get_primary_language() example
<?php
echo locale_get_primary_language('zh-Hant');
?>
Example #2 OO example
<?php
echo Locale::getPrimaryLanguage('zh-Hant');
?>
The above example will output:
zh
The behaviour when a falsy value is passed as the $locale is undocumented, but it appears that it returns the primary language of the default system language. In my case:
Locale::getPrimaryLanguage(null);
Returns 'en'. So make sure to test $locale before passing it to the method.
