带有时间戳列表的事件列表，在表格显示中按小时分组，在 PHP 中.

The table is built with Drupals theme_table(), which I can build up from any array, bearing arrays for each row. the Drupal part, however, is of little interest here :)

当前代码(片段):

<?php
//inside function that builds the content for the page linked to above:
$this_morning = _playdates_get_start_of_day_with($timestamp);
$this_night = _playdates_get_end_of_day_with($timestamp);
$nodes = _playdates_load_all_in_range($types, $this_morning, $this_night);
usort($nodes, '_playdates_cmp_titles');
//we now have a list of "nodes", being the events listed in the first column, which have
//  a list of playdates, the timestamps. $node->nid is a unique id for each event.  
foreach ($nodes as $node) {
  $times = $dates = array();
  if (is_array($node->starts_at)) {
    foreach ($node->starts_at as $starts_at) {
      $date = getdate($starts_at);
      $dates[$starts_at] = $date;
      if (!isset($active) && ($timestamp <= ($date[0] + $timezone))) {
        $active = _playdates_get_idx_hour($date);
      }
    }
    $times = _playdates_group_by_hour($dates);
    foreach ($times as $key => $value) {
      $header_times[$key] = $key;
    }
    $header = array_merge($header, $header_times);
    $entries[$node->nid] = $node;
    $entries[$node->nid]->times = $times;
  }
}

function _playdates_group_by_hour($timestamps, $playdate = NULL) {
  $indexes = array();
  foreach ($timestamps as $key => $value) {
    $indexes[_playdates_get_idx_hour($value)] = theme('playdates_format_time', $value, $playdate);
  }
  ksort($indexes);
  return $indexes;
}   

function _playdates_get_idx_hour($date) {
  return playdates_format_date($date[0], 'custom', 'H:00');
}

所以，模式是:抓取(并排序)事件列表.循环，对于每个事件，循环时间戳并创建一个数组，键是时间戳的小时(按小时分组).
