Add key-value pair in every array element in multidimension array

Question

Is it possible without using foreach to add key-value to the every array element? I need to add at the end of all arrays type => image. I have array like this:

array(5) {
  [0]=>
  array(7) {
    ["idfile"]=>
    string(2) "71"
    ["iduser"]=>
    string(1) "1"
    ["name"]=>
    string(60) "11745552_873843849371628_3215645663726390853_n-57335133dee48"
    ["extension"]=>
    string(3) "jpg"
    ["isImage"]=>
    string(1) "1"
    ["is_deleted"]=>
    string(1) "0"
    ["add_date"]=>
    string(19) "2016-05-11 15:35:15"
  }
  [1]=>
  array(7) {
    ["idfile"]=>
    string(2) "72"
    ["iduser"]=>
    string(1) "1"
    ["name"]=>
    string(19) "black-57335133e1ded"
    ["extension"]=>
    string(3) "jpg"
    ["isImage"]=>
    string(1) "1"
    ["is_deleted"]=>
    string(1) "0"
    ["add_date"]=>
    string(19) "2016-05-11 15:35:15"
  }
  [2]=>
  array(7) {
    ["idfile"]=>
    string(2) "73"
    ["iduser"]=>
    string(1) "1"
    ["name"]=>
    string(21) "Canon_1-57335133e4394"
    ["extension"]=>
    string(3) "jpg"
    ["isImage"]=>
    string(1) "1"
    ["is_deleted"]=>
    string(1) "0"
    ["add_date"]=>
    string(19) "2016-05-11 15:35:15"
  }
}

can you edit and show what you want to be the result array. also you are saying without foreach - is this exclude for loop as well? — Nick

You can use array_walk() and define the first argument of your callback as reference, but I assume foreach is a bit faster.

array_walk($array, function (&$value) {
    $value['type'] = 'image';
});
