Thank-you for reopening the question alex.

这是一个应该引起函数式程序员共鸣的解决方案.

This is a solution that should resonate with functional programmers.

function halfHourTimes() {
  $formatter = function ($time) {
    if ($time % 3600 == 0) {
      return date('ga', $time);
    } else {
      return date('g:ia', $time);
    }
  };
  $halfHourSteps = range(0, 47*1800, 1800);
  return array_map($formatter, $halfHourSteps);
}
