array_merge was replaced by the operator + but the merge parameters were reversed causing lesser priority language settings to override the most important ones.

<?php require_once 'Zend/Locale.php';

$locale = new Zend_Locale(); $language = setlocale(LC_ALL, 0); $httplanguages = getenv('HTTP_ACCEPT_LANGUAGE'); echo ($language), '
'; echo ($httplanguages), '
'; print_r($locale->getBrowser()); echo <<

Note

I'm getting this: LC_COLLATE=C;LC_CTYPE=English_United States.1252;LC_MONETARY=C;LC_NUMERIC=C;LC_TIME=C fr-fr,fr;q=0.8,en-us;q=0.6,en;q=0.4,ja;q=0.2 Array ( [en] => 1 [fr_FR] => 1 [fr] => 1 [en_US] => 0.6 [ja] => 0.2 )

But I'm excpeting that: LC_COLLATE=C;LC_CTYPE=English_United States.1252;LC_MONETARY=C;LC_NUMERIC=C;LC_TIME=C fr-fr,fr;q=0.8,en-us;q=0.6,en;q=0.4,ja;q=0.2 Array ( [fr_FR] => 1 [fr] => 1 [en_US] => 0.6 [en] => 0.6 [ja] => 0.2 )

PS: I also wonder why the qualities are not preserved: [fr_FR] should be 0.8 and [en] 0.4 Is it done on purpose? END;
