嘗試按日期按事件分組PHP

Question

我從數據庫中抓取事件列表，並嘗試將日期與一個標題關聯起來。截至目前我使用的是<dl><dt><dd>等。這可能會改變，但我認爲它不會影響我的問題的整體影響。

基本上我想通過查詢搶5個最新事件：

global $wpdb; 

$sql = "SELECT e.*, c.*, ese.start_time, ese.end_time 
     FROM wp_events_detail e 
     JOIN wp_events_category_rel r ON r.event_id = e.id 
     JOIN wp_events_category_detail c ON c.id = r.cat_id 
     LEFT JOIN wp_events_start_end ese ON ese.event_id= e.id 
     WHERE e.is_active = 'Y' 
     AND c.category_identifier = 'main' 
     ORDER BY e.start_date ASC 
     LIMIT 0, 5"; 
$results = $wpdb->get_results($sql); 

我然後循環他們通過foreach()：

if(count($results) > 0) { 

    echo '<div class="calendar-list">'; 

    foreach($results as $event) { 

     $event_id = $event->id; 
     $event_name = $event->event_name; 
     $start_date = $event->start_date; 
     $start_time = $event->start_time; 

     $start_time = strtotime($start_time); 
     $start_time = date('g:ia', $start_time); 

     $the_time = strtotime($start_date); 

     $the_day = date('d', $the_time); 
     $the_month = date('M', $the_time); 

     echo '<dl class="calendar-day first-child">'; 
     echo '<dt>'; 
     echo '<p class="the-month">' . $the_month . '</p>'; 
     echo '<p class="the-day">' . $the_day . '</p>'; 
     echo '</dt>'; 
     echo '<dd>'; 
     echo '<h4><a href="' . $event_id . '">' . $event_name . '</a></h4>'; 
     echo '<h5><span class="time">' . $start_time . '</span></h5>'; 
     echo '</dd>'; 
     echo '</dl>'; 

    } 

    echo '</div>'; 
} 

我的主要問題是我需要找出一個將日期相互關聯的方式。例如，6月27日。如果有兩個日期，我想它看起來像：

<div class="calendar-list"> 
    <dl class="calendar"> 
     <dt> 
      <p class="the-month">JUN</p> 
      <p class="the-day">27</p> 
     </dt> 
     <dd> 
      <h4><a href="#">Title</a></h4> 
         <h5><span class="time">Time</span></h5> 
     </dd> 
     <dd> 
      <h4><a href="#">Title</a></h4> 
         <h5><span class="time">Time</span></h5> 
     </dd> 
    </dl> 
    <dl class="calendar"> 
     <dt> 
      <p class="the-month">JUN</p> 
      <p class="the-day">28</p> 
     </dt> 
     <dd> 
      <h4><a href="#">Title</a></h4> 
         <h5><span class="time">Time</span></h5> 
     </dd> 
     </dl> 
</div> 

我很不確定如何實現這一點。我一直在努力設置和解決一些變數，但一直未能取得理想的結果。

如果有人能指出我該做什麼的正確方向，那將是非常感謝。

謝謝！

基本上，你要記住，從每一行$the_time在你的循環結束，並將其與當前$the_time來決定，如果你有呼應新<dt>。但是，每天都有自己的<dl>這一事實使事情變得複雜一些。這裏是一個醜陋的解決方案：

// Init empty previous time 
$previous_time = null; 
// Open first definition list 
echo '<dl class="calendar-day first-child">'; 
foreach($results as $event) { 

    $event_id = $event->id; 
    $event_name = $event->event_name; 
    $start_date = $event->start_date; 
    $start_time = strtotime($event->start_time); 
    $the_time = $start_time; 
    $the_day = date('d', $start_time); 
    $the_month = date('M', $start_time); 
    $start_time = date('g:ia', $start_time); 

    // Date changed 
    if($the_time != previous_time) { 
     // Unless first iteration, close previous list 
     if(!empty($previous_time)) { 
      echo '</dl>'; 
     } 
     // Open new list 
     echo '<dl class="calendar-day first-child">' 
     // Show definition term for the group of events 
     echo '<dt>'; 
     echo '<p class="the-month">' . $the_month . '</p>'; 
     echo '<p class="the-day">' . $the_day . '</p>'; 
     echo '</dt>'; 
    } 

    // Display current event 
    echo '<dd>'; 
    echo '<h4><a href="' . $event_id . '">' . $event_name . '</a></h4>'; 
    echo '<h5><span class="time">' . $start_time . '</span></h5>'; 
    echo '</dd>'; 

    // Remember date from previous row 
    previous_time = $the_time; 
} 
// Close last definition list 
echo '</dl>';
