add new index using array map function in php without using looping function

Question

this is my array

Array
(
    [0] => Array
        (
            [id] => 277558
            [text_value] => Jif
            [response_count] => 13
            [response_percentage] => 92
        )
    [1] => Array
        (
            [id] => 277559
            [text_value] => Peter Pan
            [response_count] => 20
            [response_percentage] => 6
        )
)

after completing the operation the out put should be

Array
(
    [0] => Array
        (
            [id] => 277558
            [text_value] => Jif
            [response_count] => 13
            [response_percentage] => 92
            [encode_param]=>ds!@@^(*!ggsfh8236542jsdgf82*&61327
        )
    [1] => Array
            (
                [id] => 277559
                [text_value] => Peter Pan
                [response_count] => 20
                [response_percentage] => 6
                [encode_param]=>ds!@@^(*!ggsfh8236542jsdgf82*&61327
            )
)

you can see a new array value encode_paramis added

in that function do some encode algorithms

i have achieve this in the foreach looping statement but i need to do it in array maping

Can anybody help thank u in advance

Have you actually looked at array_map() or array_walk() at all? — Mark Baker

$encode_func = function($elem) {   // declare function to encode
  return $elem['text_value']; 
}

$result = array_map(function($elem) use($encode_func) { 
  $elem['encode_param'] = $encode_func($elem);
  return $elem;
}, $array);

Hope it helps.

@DeepakKumar Are you sure you pass your array as last param in call to array_map()?
