Sort an array with special characters in PHP

Question

I have an array that holds the names of languages in spanish:

$lang[\"ko\"] = \"coreano\"; //korean
$lang[\"ar\"] = \"árabe\"; //arabic
$lang[\"es\"] = \"esp         


        

Answer 1

You defined your locale incorrectly in setlocale().

Change:

setlocale(LC_ALL,'es_ES.UTF-8');

To:

setlocale(LC_ALL,'es_ES');

Output:

Array ( [ar] => árabe [ko] => coreano [es] => español [fr] => francés )
