php - PHP数组组合

Question

我想要实现的是显示所有会话时间，并且在所有工作日中都有每个时间，然后每个工作日将显示一个或多个事件（如果有的话）。

我可以得到时间和工作日，但不能得到那些日子的事件。我已经提供了我的数组和代码，看看我能不能得到一些帮助。

我的会话时间

Array
(
[06:00:00] => 06:00:00
[07:00:00] => 07:00:00
[08:00:00] => 08:00:00
[09:00:00] => 09:00:00
[09:30:00] => 09:30:00
[17:30:00] => 17:30:00
[18:00:00] => 18:00:00
[18:30:00] => 18:30:00
[19:30:00] => 19:30:00
)

我的活动

Array
(
[0] => stdClass Object
(
[class_id] => 1
[class_name] => Fit Box
[class_description] => Fitbox is a high energy aerobic workout utilizing focus pads, kick pads, heavy bags, and speed balls. This class increases muscle strength and cardiovascular fitness and also includes strength and endurance circuit style training. Excellent for co-ordination, reflexes and to pump out the adrenalin! The class is 1 hour in duration.
[class_time] => 06:00:00
[class_day] => Tuesday
[class_status] => active
[class_colour] => blue
)

[1] => stdClass Object
(
[class_id] => 2
[class_name] => Hot Boxing
[class_description] => test description
[class_time] => 08:00:00
[class_day] => Wednesday
[class_status] => active
[class_colour] => grey
)

[2] => stdClass Object
(
[class_id] => 3
[class_name] => Punch Face
[class_description] => test again
[class_time] => 09:00:00
[class_day] => Thursday
[class_status] => active
[class_colour] => grey
)

[3] => stdClass Object
(
[class_id] => 4
[class_name] => MOS
[class_description] => test again
[class_time] => 19:30:00
[class_day] => Monday
[class_status] => active
[class_colour] => yellow
)

[4] => stdClass Object
(
[class_id] => 5
[class_name] => Yoga
[class_description] => test description
[class_time] => 08:00:00
[class_day] => Wednesday
[class_status] => active
[class_colour] => grey
)

)

这是我试图完成这项工作的代码。

    $result_array = array();
$days_array = array("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday");

foreach($timetable_times as $time_key => $time_value)
{
    // initialize all the days of the week for each time entry
    $result_array[$time_value['time']] = array();
    foreach($days_array as $day) {
        $result_array[$time_value['time']][$day] = "";
    }

    if (array_key_exists($day, $timetable_classes)) {
        $event_entry = $timetable_classes[$time_value['time']];
        foreach($event_entry as $event_day => $events) {
            $result_array[$time_value['time']][$day][] = $events;
        }
    }
}

print_r($result_array);

我很感激帮助。

这就是我想要的结果

$arr = array(
    "06:00:00" => array(
                                                    "Sunday" => array(

                                                                'event_desc' => "item_1",
                                                                'event_link' => "item_1",

                                                        "Monday" => array(
                                                                array(

                                                                        ),

首先创建一个函数，它将在您的列表中搜索与工作日和时间段匹配的条目（这个带有闭包的实现需要 php 5.3，但对于旧版本，实现应该是微不足道的）

<?php
function getClassesAt($day, $timeslot, $classes){
    $matches = array_filter($classes, function($class) use ($day, $timeslot){
        return ($class->class_day == $day && $class->class_time == $timeslot);
    });
    if(count($matches) == 0) return "";
    $ret = array();

    foreach($matches as $match){
        $ret[] = array("title"=>$class->class_name,
                        "description"=>$class->class_description,
                        "link"=>"???");
    }
    return $ret;
}

然后构建一个容器数组，其中包含每个会话密钥的工作日密钥数组

$days = array("Monday"=>"","Tuesday"=>"","Wednesday"=>"","Thursday"=>"","Friday"=>"","Saturday"=>"","Sunday"=>"");
$results = array_combine($sessions, array_pad(array(), count($sessions), $days));

上述代码最后一行的替代方法是

$results = array();
foreach ($sessions as $session){
     $results[$session] = $days;
}

然后遍历该数组的叶子，调用并分配 getClassesAt 函数。

foreach($results as $timeslot =>&$weekdays){
    foreach ($weekdays as $weekday=>$res){
        $weekdays[$weekday] = getClassAt($weekday, $timeslot, $classes);
    }
}

警告这只是部分测试，所以我只有大约 60% 的把握它会做你想要的，但它所基于的逻辑可能会为你指明正确的方向。

根据新提供的代码，这里是一个可行的解决方案。

<?php
$classes = array(
                    array(
                        "class_id" => 1,

输出是
