PHP: any function that i give as arguments the array and a key of that array and it returns the value of the array?

Question

Hi,

I have this array:

$a = array('it' => 'italiano',
                 'fr' => 'francese',
                 'en' => 'inglese',
                 'es' => 'spagnolo',
                 'de' => 'deutsch',

               );

Is there any function that i give as arguments the array and a key (for example 'en') and it returns 'inglese'?

Regards

Javi

Answer 1

This doesn't necessitate a function. This is just standard array access logic.

$a['en']

Or if $key was 'en', then

$a[$key]

Answer 2

Why not simply do:

echo $a['en'];

This will give you inglese

Answer 3

$languageName = 'Default';
$languageCode = 'en';
if (isset($a[$languageCode])) {
   $languageName = $a[$languageCode];
}

Answer 4

What's wrong with using $a['en']? Which would give 'inglese' as well.

function get_value($array, $key){
  return (isset($array[$key]) ? $array[$key] : null;
}

echo get_value($array, 'en'); # => echoes inglese

Answer 5

function language($array, $language){
    if(isset($array[$language]))
       return $array[$language];
    else 
       return false;
}

$language = language($a, 'en');

if($language != false)
  echo $language;

Answer 6

There are a couple of ways you can do this

$a = array(
      'it' => 'italiano',
      'fr' => 'francese',
      'en' => 'inglese',
      'es' => 'spagnolo',
      'de' => 'deutsch',
     );

$lang = 'it';
echo getValueFromKey($a,$lang);

function getValueFromKey($array,$key) {
   return $array[$key];
}

or like this

echo $a['it'];
