Using preg_match on a multidimensional array to return key values arrays

Question

I have an array that is structured as such:

$data = array(
    \"abc\"=>array(
            \"label\" => \"abc\",
            \"value\" => \"def\",
          


        

Answer 1

If you are using PHP 5.5 and are viewing this question in 2015, this might be a more simple answer:

$elements= array_column($array, 1); //Where 1 is the name of the column or the index
$foundElements = preg_grep("/regex/i", $elements);
