Accessing form data form JSON object converted to associative array in PHP

Question

I'm sending the HTML FORM data with AJAX to PHP script and I'm converting the data to associative array like this:

$json = json_decode($request->get('json'),true);

so, when I'm dumping the variable I get this array:

array(11) {
  [0]=>
  array(2) {
    ["name"]=>
    string(21) "form[pickupDate][day]"
    ["value"]=>
    string(1) "4"
  }
  [1]=>
  array(2) {
    ["name"]=>
    string(23) "form[pickupDate][month]"
    ["value"]=>
    string(1) "1"
  }
  [2]=>
  array(2) {
    ["name"]=>
    string(22) "form[pickupDate][year]"
    ["value"]=>
    string(4) "2016"
  }
  [3]=>
  array(2) {
    ["name"]=>
    string(22) "form[pickupTime][hour]"
    ["value"]=>
    string(1) "0"
  }
  [4]=>
  array(2) {
    ["name"]=>
    string(21) "form[returnDate][day]"
    ["value"]=>
    string(1) "1"
  }
  [5]=>
  array(2) {
    ["name"]=>
    string(23) "form[returnDate][month]"
    ["value"]=>
    string(1) "1"
  }
  [6]=>
  array(2) {
    ["name"]=>
    string(22) "form[returnDate][year]"
    ["value"]=>
    string(4) "2016"
  }
  [7]=>
  array(2) {
    ["name"]=>
    string(22) "form[returnTime][hour]"
    ["value"]=>
    string(1) "0"
  }
  [8]=>
  array(2) {
    ["name"]=>
    string(19) "form[pickupAddress]"
    ["value"]=>
    string(0) ""
  }
  [9]=>
  array(2) {
    ["name"]=>
    string(12) "form[agency]"
    ["value"]=>
    string(1) "1"
  }
  [10]=>
  array(2) {
    ["name"]=>
    string(12) "form[_token]"
    ["value"]=>
    string(43) "9dh6ghpMv5K9LUdSLvh6y2NOzqTzUrOfVriL8C63Ybs"
  }
}

how can I get the value of form[pickupDate][day] without loop?

Answer 1

I was able to do it like this:

echo array_column($json, null, 'name')['form[pickupDate][day]']['value'];
