Array_search - multidimensionale

[maxtn]

Cioè? così?

$arr_testi = array("A" => "provaA", "B" => "provaB");

function txt_display($txt_pulsante)
{
if (array_key_exists($txt_pulsante, $GLOBALS[$arr_testi])):
    $GLOBALS[$txt_nome] = $arr_testi[$txt_pulsante];
endif;
return $txt_nome;
}
echo  txt_display('A'); 

mi da: Warning: array_key_exists(): The second argument should be either an array or an object
