Question

我从数据库中获取以下数组：

Array
(
[0] => Array
    (
        [facility_name] => AFC Clayton Juniors
        [day] => 15
        [month] => Apr
        [year] => 2016
        [start_time] => 20
        [end_time] => 21
    )

[1] => Array
    (
        [facility_name] => AFC Clayton Juniors
        [day] => 15
        [month] => Apr
        [year] => 2016
        [start_time] => 22
        [end_time] => 23
    )

[2] => Array
    (
        [facility_name] => Chorlton Runners
        [day] => 15
        [month] => Apr
        [year] => 2016
        [start_time] => 10
        [end_time] => 11
    )

[3] => Array
    (
        [facility_name] => Chorlton Runners
        [day] => 15
        [month] => Apr
        [year] => 2016
        [start_time] => 19
        [end_time] => 20
    )
)

我需要它嵌套如下::

Array
(
[0] => Array
    (
        [facility_name] => AFC Clayton Juniors
        [dates] => Array
               (
                    [date1] => Array
                            (
                                [date] => 15 Apr 2016
                                [timeslots] => Array
                                            (
                                              [timeslot1] => Array
                                                          (
                                                            [start_time] => 20
                                                            [end_time] => 21
                                                           )
                                              [timeslot2] => Array
                                                          (
                                                            [start_time] => 22
                                                            [end_time] => 23
                                                           )
                                            )
                    [date2] => 16 Apr 2016    //etc
              )
     )
[1] => Array
    (
      [facility_name] = Chorlton Runners
      [dates] => Array //etc
    )
)

详细说明：我需要在我的数组中没有重复的名称，并且存在同名的日期作为与日期数组匹配相同名称的新键输入，并且对于时隙也是如此。我怎么能这样做？

对于这个解决方案，我们假设从数据库中取出的数组名为$facilities。代码是：

$noDupes = array();

foreach ($facilities as $fac) {
    $facilityIndex = -1; // The index of the facility name, -1 indicates it wasn't found.
    $dateIndex = '';     // The index of the date string, an empty string indicates it wasn't found.
    $timeslotIndex = ''; // The index of the timeslot, an empty string indicates it wasn't found.
    $facDate = "{$fac['day']} {$fac['month']} {$fac['year']}"; // The date string (dd mmm aaaa)

    foreach ($noDupes as $f => $facility) {
         if ($fac['facility_name'] == $facility['facility_name']) {
            // If the facility name was found we take the corresponding index (0, 1, 2, etc.).
            $facilityIndex = $f;

            foreach ($facility['dates'] as $d => $date) {
                if ($facDate == $date['date']) {
                    // If the date string was found we take the corresponding index (date1, date2, date3, etc.).
                    $dateIndex = $d;

                    foreach ($date['timeslots'] as $t => $timeslot) {
                        if ($fac['start_time'] == $timeslot['start_time'] && $fac['end_time'] == $timeslot['end_time']) {
                            // If the timeslot was found we take the corresponding index (timeslot1, timeslot2, timeslot3, etc.).
                            $timeslotIndex = $t;
                            break; // end timeslot loop
                        }
                    }

                    break; // end date loop
                }
            }

            break; // end facility loop
        }
    }

    if ($facilityIndex == -1) {
        // Take the new index for the date and timeslot if-statements
        $facilityIndex = count($noDupes);

        $noDupes[] = array(
            'facility_name' => $fac['facility_name'],
            'dates' => array()
        );
    }

    if ($dateIndex == '') {
        // Calculate the new index for the date (date1, date2, etc.)
        $dateNum = count($noDupes[$facilityIndex]['dates']) + 1;
        $dateIndex = "date{$dateNum}";

        $noDupes[$facilityIndex]['dates'][$dateIndex] = array(
            'date' => $facDate,
            'timeslots' => array()
        );
    }

    if ($timeslotIndex == '') {
        // Calculate the new index for the timeslot (timeslot1, timeslot2, etc.)
        $timeslotNum = count($noDupes[$facilityIndex]['dates'][$dateIndex]['timeslots']) + 1;
        $timeslotIndex = "timeslot{$timeslotNum}";

        $noDupes[$facilityIndex]['dates'][$dateIndex]['timeslots'][$timeslotIndex] = array(
            'start_time' => $fac['start_time'],
            'end_time' => $fac['end_time']
        );
    }
}

使用JSON数组将使您的任务变得非常简单，并且在PHP中受支持
