I know I can translate to current website language with t() function, but I need translate to specified (not current) language, my site has three languages and I want get English of some of the worlds in some template files when current language is French. How can I get translate of string according to specified language instead of current language?
According to t() documentation you can pass specified language it
As Example below code return French translate of
language string without consider current site language.
$fr_value = t('language', array(), array('langcode' => 'fr'));
