php - PHP 配列の結合

Question

私が達成しようとしているのは、すべてのセッション時間を表示し、毎回すべての曜日を表示することです。次に、各曜日に 1 つ以上のイベントが表示されます。

時間と曜日は取得できますが、その日のイベントは取得できません。配列とコードを提供して、助けが得られるかどうかを確認しました。

私のセッション時間

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
)

マイイベント

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
)

)

そして、これは仕事をしようとする私のコードです。

    $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);

助けてくれてありがとう。

最初に、曜日と時間帯に一致するエントリをリストから検索する関数を作成します (クロージャを使用したこの実装には php 5.3 が必要ですが、古いバージョンの場合、実装は簡単なはずです)。

<?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;
}

次に、各セッションキーの曜日キーを含む配列を持つコンテナー配列を構築します。

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

上記のコードの最後の行に代わるものは次のとおりです。

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

次に、getClassesAt 関数を呼び出して割り当てる配列のリーフをたどります。

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

警告これは部分的にしかテストされていないため、希望どおりに動作することは約 60% しかないと確信していますが、それが基づいているロジックは正しい方向を示している可能性があります。
