从Array中获取价值

Question

I am trying to get a certain value out of an array. Example of the array is:

array(2) {
  ["error"]=>
  array(0) {
  }
  ["result"]=>
  array(1) {
    ["open"]=>
    array(1) {
      ["12345-AAAAA-66AAKK"]=>
      array(14) {
        ["inf"]=>

Usually when I want a certain value I would use:

$datawanted=$data[result][open][value];

However, in this case the first array is a variable that always changes (12345-AAAAA-66AAKK), I need to find the value of that.

I tried getting this with reset() and key[0] but this not give the wanted result.

Is there a way to get the output of the first element in the result array?

You can use array_search: http://php.net/manual/de/function.array-search.php

Example:

foreach ($array['result']['open'] as $dynamicKey => $item) {
    if ($key = array_search('Value you are looking for', $item) {
       $datawanted=$array['result']['open'][$dynamicKey][$key];
    }
}
