I have this array in PHP:

```
Array
(
    [en-CA] => English
    [fr-CA] => Français
    [es-ES] => Español
)

```

I would like to get the language name from the key.

So I made this but it doesn't work:

```
$lang = "en-CA";
$curLang = array_search($lang, $languages);

```

`$curLang` returns me nothing.

Thanks.
