如何在 PHP 中将数组转换为不带 .= 的列表？

我有以下数组输出。

Array
(
    [day] => 17
    [eventContent] => event 1 of 17th
    [eventTitle] => 17th event 1
)

Array
(
    [day] => 19
    [eventContent] => event 1 of 19th
    [eventTitle] => 19th event 1
)

Array
(
    [day] => 05
    [eventContent] => event 1 of 5th
    [eventTitle] => 5th event 1
)

Array
(
    [day] => 17
    [eventContent] => event 2 of 17th
    [eventTitle] => 17th event 2
)

Array
(
    [day] => 19
    [eventContent] => event 2 of 19th
    [eventTitle] => 19th event 2
)

Array
(
    [day] => 19
    [eventContent] => event 3 of 19th
    [eventTitle] => 19th event 3
)
...
...

现在我想让它像下面这样。

以19号为例

<li>
<span class="title">19th event 1</span>
<span class="desc">event 1 of 19th</span>
</li>
<li>
<span class="title">19th event 2</span>
<span class="desc">event 2 of 19th</span>
</li>
<li> 
<span class="title">19th event 3</span>
<span class="desc">event 3 of 19th</span>
</li>

我尝试了以下方法。它在 PHP 中工作正常，但在 Codeigniter 中却不行。所以我希望有人能告诉我另一种方法来处理 out .=

提前致谢。

$events[intval($row_event->day)] .= '<li><span class="title">'
.stripslashes($row_event->eventTitle).
'</span><span class="desc">'.stripslashes($row_event->eventContent).
'</span></li>';

以下是该模型的详细信息。

$events = array();

//query the database for events between the first date of the month and the last of date of month
// $result = mysql_query("SELECT DATE_FORMAT(eventDate,'%d') AS day,eventContent,eventTitle FROM eventcal WHERE eventDate BETWEEN  '$current_year/$current_month/01' AND '$current_year/$current_month/$total_days_of_current_month'");

$query = $this->db->query("SELECT DATE_FORMAT(eventDate,'%d') AS day,eventContent,eventTitle FROM eventcal WHERE eventDate BETWEEN  '$current_year/$current_month/01' AND '$current_year/$current_month/$total_days_of_current_month'");
foreach ($query->result_array() as $row_event)
{

$events[intval($row_event['day'])] .= '<li><span class="title">'
.stripslashes($row_event['eventTitle']).'</span><span class="desc">'
.stripslashes($row_event['eventContent']).'</span></li>';
...
...

这可以简化很多。首先，看看CI的数据库类中的Active Record，它会让你的DB调用变得100%容易。

为什么不能将数组传递回视图并将其注入那里？

你的观点可能看起来像

<?php foreach ($row_event as $event) : ?>
  <li>
  <span class="title"><?php echo $event->eventTitle; ?></span>
  <span class="desc"><?php echo $event->eventContent; ?></span>
  </li>
<?php endforeach; ?>

这将循环遍历您的一系列事件详细信息并列出您的列表。
