Question

我正在努力计算某一特定地点某一天（今天）的总事件数。使用24小时的时间，我试图在foreach循环中找到当天的最后一个事件，然后当当天最后一个事件的end_time比现在少时，显示文本，“所有预定的事件今天结束了。”

我的问题是xml数据包括所有房间中的所有事件14天而且我没有得到正确的计数。我在foreach中有一些if语句可以减少它....

如果xml space id == room id，那么如果xml事件start_date等于今天，那么 if（$ i＆lt; $ numItems）如果事件结束时间大于现在，展示那些事件

当满足这些条件时，我需要记录的数量...当事件是今天的日期，并且在与通过url传递的roomID相同的房间中。在foreach计算太多记录并将计数放在foreach中之前将$ numItems = $ count（$ arr）放入，总是只返回1。

$arr = $this->data['events'];
$numItems = count($arr);
$i = 1;
foreach ($arr as $key => $reservation){
if ((int)$reservation->space_reservation->space_id == $roomID) 
{
//test today's date
        $resDT = date('m/d/y',strtotime($reservation->reservation_start_dt));
        if ($resDT == date('m/d/y'))
            {
            if ($i < $numItems)
            {
            $repst = substr($reservation->event_start_dt,11,5);
            $repet = substr($reservation->event_end_dt,11,5);

                if ( (date('H:i',strtotime($repet))) > (date('H:i')) )
                    {
                    echo '<h2>' .$reservation->event_name. '</h2> ';
                    echo '<span class="dates">' .date('m/d/y',strtotime($reservation->event_start_dt)). ' </span> ';
                    echo '<span class="times">' .date('g:i a',strtotime($repst)). ' - ';
                    echo date('g:i a',strtotime($repet)). '</span> ';
                    echo '<br />';
                    } // ends if event end date has passed

            //echo '<span style="color:#FFF200;">'.$i.'</span>';
            echo '<br />';
            }
//if $i equals last record
            elseif ($i === $numItems) {
                // test if last event ends show
                if ( (date('g:i a',strtotime($repet))) < (date('g:i: a')) ){
                echo '<span style="color:#FFF200;">All scheduled meetings/events have concluded for today. </span><br /><br />';
                }
            }
            $i++;
            } // ends if

    } // ends if
} // ends for each

以下代码将打印其中一个：

今天所有未完成的事件仅限于给定的房间;
“所有预定活动已于今天结束。”如果没有剩下的话。

我添加了两个计数器，供您根据需要使用：

$ totalEventsToday - 计算在给定房间内今天安排的所有活动;
$ unfinishedEventsToday - 计算今天在结束日期/时间尚未过去的特定房间内安排的事件。

所以这是代码：

$today                 = date('m/d/y');
$events                = $this->data['events'];
$totalEventsToday      = 0;
$unfinishedEventsToday = 0;

// Check all reservations/events
foreach ($events as $reservation) {

    // Process reservation/events for the given room only
    if ((int) $reservation->space_reservation->space_id == $roomID) 
    {
        // Process reservation/events for today only
        $resDT = date('m/d/y', strtotime($reservation->reservation_start_dt));
        if ($resDT == $today)
        {
            $totalEventsToday++;

            $repst = substr($reservation->event_start_dt,11,5);
            $repet = substr($reservation->event_end_dt,11,5);

            // Process unfinished event
            if ((date('H:i',strtotime($repet))) > (date('H:i')))
            {
                $unfinishedEventsToday++;

                echo '<h2>' .$reservation->event_name. '</h2> ';
                echo '<span class="dates">' .date('m/d/y',strtotime($reservation->event_start_dt)). ' </span> ';
                echo '<span class="times">' .date('g:i a',strtotime($repst)). ' - ';
                echo date('g:i a',strtotime($repet)). '</span> ';
                echo '<br />';
            } // ends if unfinished event
         } // ends if today
    } // ends if room
} // ends for each

// Test if there aren't any unfinished events left for today
if (!$unfinishedEvents){
    echo '<span style="color:#FFF200;">All scheduled meetings/events have concluded for today. </span><br /><br />';
}

我想我不确定你的问题在哪里。你可以简单地添加一个计数器，就像我在下面$currentEvents所做的那样。

$arr = $this->data['events'];
$numItems = count($arr);
$currentEvents = 0;
$i = 1;
foreach ($arr as $key => $reservation){
if ((int)$reservation->space_reservation->space_id == $roomID) 
{
//test today's date
        $resDT = date('m/d/y',strtotime($reservation->reservation_start_dt));
        if ($resDT == date('m/d/y'))
            {
            if ($i < $numItems)
            {
            $repst = substr($reservation->event_start_dt,11,5);
            $repet = substr($reservation->event_end_dt,11,5);

                if ( (date('H:i',strtotime($repet))) > (date('H:i')) )
                    {
                    $currentEvents++;
                    echo '<h2>' .$reservation->event_name. '</h2> ';
                    echo '<span class="dates">' .date('m/d/y',strtotime($reservation->event_start_dt)). ' </span> ';
                    echo '<span class="times">' .date('g:i a',strtotime($repst)). ' - ';
                    echo date('g:i a',strtotime($repet)). '</span> ';
                    echo '<br />';
                    } // ends if event end date has passed

            //echo '<span style="color:#FFF200;">'.$i.'</span>';
            echo '<br />';
            }
//if $i equals last record
            elseif ($i === $numItems) {
                // test if last event ends show
                if ( (date('g:i a',strtotime($repet))) < (date('g:i: a')) ){
                echo '<span style="color:#FFF200;">All scheduled meetings/events have concluded for today. </span><br /><br />';
                }
            }
            $i++;
            } // ends if

    } // ends if
} // ends for each

php计数并获取foreach循环中的最后一条记录
