One shall not use PHP variables of any kind inside a translation function's string because translation relies on looking up strings in a table and then translating them. That is done by code which scans your PHP code (NOT executing it) and pulls out all the __()’s it finds, then builds the list of strings to be translated. That scanning code cannot possibly know what is inside $string. And ideally, phrases should be translated, not words.
