如何在PHP中将数组转换为无。 [英] How to convert array to list without .= in PHP?

问题描述

我有以下数组输出。

 数组
（
 [day] => 17 
 [eventContent] =>事件1 of 17th 
 [eventTitle] =>第17个事件1 
）
 
数组
 b [day] => 19 
 [eventContent] =>第1个第19个
 [eventTitle] =>第19个事件1 
）
 
 b $ b（
 [day] => 05 
 [eventContent] =>第5个活动第1个
 [eventTitle] =>第5个活动1 
）
 
 Array 
（
 [day] => 17 
 [eventContent] =>第17项的事件2 
 [eventTitle] =>第17项事件2 
）
 
 Array 
（
 [day] => 19 
 [eventContent] =>事件2 of 19th 
 [eventTitle] =>第19个事件2 
）
 
数组
（
 [day] => 19 
 [eventContent] => 
 [eventTitle] =>第19个事件3 
）
 ... 
 ... 
  

例如第19个

 < li> 
< span class =title>第19个活动1< / span> 
< span class =desc>第19个活动1< / span> 
< / li> 
< li> 
< span class =title>第19个活动2< / span> 
< span class =desc>第19个活动2< / span> 
< / li> 
< li> 
< span class =title>第19个活动3< / span> 
< span class =desc>第19个活动3< / span> 
< / li> 
  

我试过下面的。它在PHP中工作正常，但不是在Codeigniter。所以我希望有人能告诉我另一种方法。=

提前感谢。

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

以下是模型的详细信息。

  $ events = array（）; 
 
 //查询数据库中每月第一个日期和月份最后一个日期之间的事件
 // $ 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>'; 
 ... 
 ...

解决方案

位。首先，看看CI的数据库类中的Active Record，它会使你的数据库调用更容易100％。

为什么不能将数组传回视图并注入

 <？ 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; > 
  

这将循环浏览您的活动详细资料数组并列出。

I have the following array outputs.

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
)
...
...

Now I want to make it like the followings.

For example for 19th

<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>

I tried the following. It works fine in PHP but not in Codeigniter. So I am hoping someone can tell me another way to do with out .=

Thanks in advance.

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

And the following is the details of the model.

$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>';
...
...

解决方案

This can simplified quite a bit. First, look at Active Record in CI's database class, it will make your DB calls 100% easier.

Why can't you pass the array back to the view and inject it there?

Your view may look like

<?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; ?>

That will loop through your array of event details and make your list.
