PHP计数并获取foreach循环中的最后一条记录 - php count and get last record in foreach loop

我正在尝试能够计算给定日期(今天)特定地点的总事件。使用24小时时间，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小于现在时，显示文本，"今天所有计划的事件都已结束。"

我的问题是xml数据包括所有房间14天的所有事件，我没有得到正确的计数。我在foreach中有几个if语句来简化它....

如果XML空间id ==房间id，则如果XML事件start_date等于今天，则If ($i <numItems美元)如果事件结束时间大于现在，显示这些事件>

我需要满足这些条件时的记录计数…当事件是今天的日期，并且与通过url传递的roomID在同一个房间时。把我的$numItems = $count($arr)放在foreach之前计算太多的记录，并且在foreach中放入一个计数总是只返回1的计数。

$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

下面的代码将打印其中一个:

今天所有未完成的活动仅针对给定房间;
如果所有预定的活动都已结束，则显示"All scheduled events for today."

我添加了两个计数器供您使用:

$totalEventsToday -计算给定房间今天安排的所有事件;
$unfinishedEventsToday -计算今天在给定房间中计划的事件，其结束日期/时间尚未过去。

代码是这样的:

$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 />';
}

我想我真的不知道你的问题在哪里。您可以简单地添加一个计数器，就像我在下面对$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
