PHP 的时间范围数组问题

问题描述 投票：0回答：4

我正在尝试编写一个用于预订机场时段的应用程序，基本上有一个开放和关闭时段以及时间间隔，然后该应用程序在两个时间值之间循环并显示一个选择下拉列表。

我需要为机场建立一个选项来限制时间范围，例如每周四上午 10:00 到中午 12:00 之间，机场不接受预订，我需要将其构建到循环中，但无法使其正常工作。它需要是特定日期（周一至周日）而不是特定日期，因为机场将在同一时间段内每周的每个指定日期关闭。

这是到目前为止我的代码，有人可以帮忙吗？

<?php

$open_from = "09:00";
$open_to = "17:00";
$interval = "15 mins";  

$today_number = date('w');

$intervals = array(
    array(
        'day' => '4',
        'start' => '10:00',
        'end' => '12:00',
    ),
    array(
        'day' => '4',
        'start' => '12:30',
        'end' => '13:30',
    ),
    array(
        'day' => '5',
        'start' => '15:30',
        'end' => '16:00',
    ),
);  

if(!isset($_GET['date'])){                  
    $date = date('d-m-Y');          
}else{          
    $date = $_GET['date'];          
} 

function create_time_range($start, $end, $interval) { 

    $start_time = strtotime($start); 
    $end_time   = strtotime($end); 

    $current    = time(); 
    $add_time   = strtotime('+'.$interval, $current); 
    $diff       = $add_time-$current; 

    $times = array(); 
    while ($start_time < $end_time) { 
        $times[] = $start_time; 
        $start_time += $diff; 
    } 
    $times[] = $start_time; 
    return $times; 
    
}

$times = create_time_range($open_from, $open_to, $interval);

foreach ($times as $key => $time) { 
    $times[$key] = date($date.'H:i', $time); 

    foreach($intervals as $key2 => $item) {
        if($intervals[$key2]['day']==$today_number && date('H:i',$time) == $intervals[$key2]['start'] && date('H:i',$time) == $intervals[$key2]['end']){
            echo "yes";
        }else{
            echo "no";
        }
    echo "<option value='".date('H:i', $timestamp)."'>".date('H:i',$time)."</option><br>";      
    //echo $intervals[$key]['day']." - ".$intervals[$key]['start']." - ".$intervals[$key]['end'];
    //echo "<br>";
}

    
    
}

针对您的问题，您可以使用以下代码达到您想要的结果：

if(!isset($_GET['date']))
    $date = date('d-m-Y');
else
    $date = $_GET['date'];

$startTime     = '09:00';
$endTime       = '17:00';
$interval      = 15; // minutes
$day           = date('N', strtotime($date));

$bookedSlots = array(
    array(
        'day' => '4',
        'start' => '10:00',
        'end' => '12:00',
    ),
    array(
        'day' => '4',
        'start' => '12:30',
        'end' => '13:30',
    ),
    array(
        'day' => '5',
        'start' => '15:30',
        'end' => '16:00',
    ),
);

function fetchTimeIntervals($startTime, $endTime, $intervalMinutes) {
    global $day,$bookedSlots;

    $htmlContent = '';

    // Convert start and end times to DateTime objects
    $start  = new DateTime($startTime);
    $end    = new DateTime($endTime);

    // Create an interval object based on the specified minutes
    $interval = DateInterval::createFromDateString($intervalMinutes.' minutes');

    // Create a date period object based on the start, end, and interval
    $period = new DatePeriod($start, $interval, $end);

    // Iterate through each interval and check each slot whether it is booked or not
    foreach ($period as $slot) {
        foreach ($bookedSlots as $subArr) {
            $isSlotBooked = false;

            $bookedSlotStartTime = new DateTime($subArr['start']);
            $bookedSlotEndTime   = new DateTime($subArr['end']);

            if($subArr['day'] == $day && $bookedSlotStartTime->getTimestamp()-$slot->getTimestamp() <= 0 && $bookedSlotEndTime->getTimestamp()-$slot->getTimestamp() > 0)
                $isSlotBooked = true;
        }

        $disableClass = ($isSlotBooked) ? 'disabled' : '';
        $slotTime     = $slot->format("H:i");
        $htmlContent .= "<option value='{$slotTime}' {$disableClass}>{$slotTime}</option>";
    }
    return $htmlContent;
}

echo $timeIntervals = fetchTimeIntervals($startTime, $endTime, $intervalMinutes);
?>

试试这个方法：

$interval = "15 minutes";
...
$current    = time();
add_time   = strtotime($current.'+'.$interval);

您还可以向我们提供有关最终抛出的错误的更多信息吗？最终启用调试：

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

好吧，在 foreach 中，您尝试修改正在循环的同一数组（$times[$key]），但似乎没有意义。

这是在本地机器上测试的更新代码

<?php

$open_from = "09:00";
$open_to = "17:00";
$interval = "15 mins";  

$today_number = date('w');

$intervals = array(
    array(
        'day' => '4',
        'start' => '10:00',
        'end' => '12:00',
    ),
    array(
        'day' => '4',
        'start' => '12:30',
        'end' => '13:30',
    ),
    array(
        'day' => '5',
        'start' => '15:30',
        'end' => '16:00',
    ),
);  

if(!isset($_GET['date'])){                  
    $date = date('d-m-Y');          
}else{          
    $date = $_GET['date'];          
} 


$times = create_time_range($open_from, $open_to, $interval);

foreach ($times as $key => $time) { 
    $day = date('w', strtotime($date));
    $timeFrame = date('H:i', $time);
   
    foreach ($intervals as $slot) {
        if ($day == $slot['day'] && $timeFrame >= $slot['start'] && $timeFrame < $slot['end']) {
            echo 'No </br>';
        } else {
            echo 'Yes </br>';
        }
    }
}

function create_time_range($start, $end, $interval) { 

  $start_time = strtotime($start); 
  $end_time   = strtotime($end); 

  $current    = time(); 
  $add_time   = strtotime('+'.$interval, $current); 

  $diff       = $add_time-$current; 

  $times = array(); 
  while ($start_time < $end_time) { 
      $times[] = $start_time; 
      $start_time += $diff; 
  } 
  $times[] = $start_time; 
  return $times; 
  
}

看看这个。我希望我已经正确理解了您的问题并提供了所需的解决方案。

<?php
$startTime     = '09:00';
$endTime       = '17:00';
$interval      = 15; // minutes
$weekNumber    = date('w');
$excludedSlots = [
    ['day' => '4', 'start' => '10:00', 'end' => '12:00'],
    ['day' => '4', 'start' => '12:30', 'end' => '13:30'],
    ['day' => '5', 'start' => '15:30', 'end' => '16:00']
];

$timeRange = generateTimeRange($startTime, $endTime, $interval, $weekNumber, $excludedSlots);
echo $timeRange;

function generateTimeRange($startTime, $endTime, $interval, $weekNumber, $excludedSlots) {
    $timeRange = '';
    $currentTime = $startTime;

    while ($currentTime <= $endTime) {
        $isExcluded = false;

        foreach ($excludedSlots as $excludedSlot) {
            if ($weekNumber == $excludedSlot['day'] && $currentTime >= $excludedSlot['start'] && $currentTime <= $excludedSlot['end']) {
                $isExcluded = true;
                break;
            }
        }

        if (!$isExcluded) {
            $timeRange .= "<option value='{$currentTime}'>{$currentTime}</option>";
        } else {
            $timeRange .= "<option value='{$currentTime}' disabled>{$currentTime} (Blocked)</option>";
        }

        $currentTime = date('H:i', strtotime($currentTime) + ($interval * 60));
    }

    return $timeRange;
}
?>
