PHP while array

    if ($content = getData('LED'))
    {
        return $content;

$airports = array('LED','DME','SVO','VKO','AER','KRR','IKT','KGP','KHV');
foreach($airports as $airport) {
  if($content = getData($airport)) {

  }
}

Do you mean something like array_walk, in_array, foreach or array_reduce?

foreach

or while, if you prefer
