I would like to retrieve only

when Hundai is my input. Anybody suggest me solution with minimum number of loop

Answer 1

$arr = array(
  'Hyundai' => array('Sonata', 'i20', 'Santro', 'Verna'),
  'Suzuki' => array('Alto', 'Ritz'),
  'VW' => array('Polo', 'Passat', 'Vento')
);

$key = 'Hyundai';

if (isset($arr[$key]) && is_array($arr[$key])) {
  echo implode(', ', $arr[$key]);
}
