For multidimensional arrays, I noticed someone created a function called
"extract_values_by_key" but it didn't work as I wanted it to... so I created a
recursive function of my own that gets the values within a multidimensional array with a specific
key and stores them into an array in case multiple keys match the search.
/* Search for values by key within multidimensional array */

function get_values_by_key($array, $needle_key) {
static $result = array();
if (is_array($array)) {
foreach ($array as $key => $value) {
get_values_by_key($value, $needle_key);
if ($key == $needle_key && $key != "0") {
$result[] = $value;
}
}
}
return $result;
}
