Parse arrays in array by their key values

Hi,

I want to get value from this array, I only need to get words which has value N. This is array:

$myarray = array (
  'feeler gauge' => 
  array (
    0 => 'h',
  ),
  'feeler' => 
  array (
    0 => 'N',
  ),
  'feeless' => 
  array (
    0 => 'A',
  ),
  'feelingful' => 
  array (
    0 => 'A',
  ),
  'feelinglessly' => 
  array (
    0 => 'v',
  ),
  'feelingless' => 
  array (
    0 => 'A',
  ),
  'feelingly' => 
  array (
    0 => 'v',
  ),
  'feelingness' => 
  array (
    0 => 'N',
  ),
  'feeling' => 
  array (
    0 => 'N',
    1 => 'A',
  ),
  'feel' => 
  array (
    0 => 'V',
    1 => 't',
    2 => 'i',
    3 => 'N',
  ),
);

PHP:

Lets say I want to get 'feeler' which is second array and first value which contains N value in its array. Let me know plz how can I get that value.

 

why not use a foreach and checks

is array | if

 

I did something like this, but I can`t get array key. As you see this array contains values and for each value array with key and values. So i need to match last value for each array and I did it but can`t extract value name:

foreach ($myarray as $array) {
	$key = array_search('N', $array);
	echo $key;
}

PHP:

 

sorry i am spanish and.. my inglish... jajajaja

 

I'm going to give you a sample idea of how parsing arrays within arrays works:

foreach($myarray as $key => $value)
{
    // $key is now 'feeler' or 'feeless' or etc
    // $value is now the array for 'feeler' or 'feeless' or etc (the $key)
    foreach($value as $inside_key => $inside_value)
    {
         // $inside_key is now 0, 1, 2, 3, etc 
         // $inside_value is now 'h', 'N', 'A', etc
    }
}

PHP:

I'm sure you'll figure out the rest from here
