Merge php中的合并时间

我正试图找到合并时代的最佳方式。。。在用户有两件事的时间表上工作：

X天的可用性和分配小时数

两者的结构相同，如下所示：

具体日期（2012-10-07）的可用性：

[2012-10-07]
             [0][start_time] => 08:30
                [end_time]   => 13:30

             [1][start_time] => 16:30
                [end_time]   => 23:30

现在，对于特定的一天，他可能被分配，我的查询结果如下所示：

 [2012-10-07][0][start_time] => 08:30
                [end_time]   => 09:30

             [1][start_time] => 10:30
                [end_time]   => 11:30

             [2][start_time] => 17:00
                [end_time]   => 18:30

 [2012-10-07] [0][start_time]=> 08:30
                 [start_time]=> 09:30
                 [assigned]=> true

              [1][start_time]=> 09:30
                 [start_time]=> 10:30
                 [assigned]=> false

              [2][start_time]=> 10:30
                 [start_time]=> 11:30
                 [assigned]=> true

              [3][start_time]=> 11:30
                 [start_time]=> 13:30
                 [assigned]=> false

              [4][start_time]=> 16:30
                 [start_time]=> 17:00
                 [assigned]=> false

              [5][start_time]=> 16:30
                 [start_time]=> 17:00
                 [assigned]=> false

              [6][start_time]=> 17:00
                 [start_time]=> 18:30
                 [assigned]=> true

              [7][start_time]=> 18:30
                 [start_time]=> 23:30
                 [assigned]=> false

合并的结果应如下所示：

 [2012-10-07][0][start_time] => 08:30
                [end_time]   => 09:30

             [1][start_time] => 10:30
                [end_time]   => 11:30

             [2][start_time] => 17:00
                [end_time]   => 18:30

 [2012-10-07] [0][start_time]=> 08:30
                 [start_time]=> 09:30
                 [assigned]=> true

              [1][start_time]=> 09:30
                 [start_time]=> 10:30
                 [assigned]=> false

              [2][start_time]=> 10:30
                 [start_time]=> 11:30
                 [assigned]=> true

              [3][start_time]=> 11:30
                 [start_time]=> 13:30
                 [assigned]=> false

              [4][start_time]=> 16:30
                 [start_time]=> 17:00
                 [assigned]=> false

              [5][start_time]=> 16:30
                 [start_time]=> 17:00
                 [assigned]=> false

              [6][start_time]=> 17:00
                 [start_time]=> 18:30
                 [assigned]=> true

              [7][start_time]=> 18:30
                 [start_time]=> 23:30
                 [assigned]=> false

现在，当在日历上加入这两个选项时，可用性显示为绿色（false），分配为红色（assigned=true）

我所做的是循环可用性，将开始/结束时间转换为UNIX时间戳，然后循环每个分配的时间并转换为UNIX时间戳

然后测试所有情况，如果时间在可用性范围内或在可用性范围外，则添加临时数组和循环，同时不更改最终数组

（因为每次生成新时间时，我都必须在指定的时间内再次循环）

这是可行的，但我不喜欢我的方式做它。。。有更好的办法吗

更新：

  function mergeSessionFromSchedule($schedule ,$seances) {

    $sessions = removeSessionsFromSchedule($schedule,$seances);

    $mergedSessions = array_merge_recursive($sessions , $seances);

    foreach($mergedSessions as $s => $val) {
        $sortedSessions[$s] = subval_sort_by_time($val,'heure_debut'); 
    }



    return $sortedSessions ;
   }

    function subval_sort_by_time($a,$subkey) {
        foreach($a as $k=>$v) {
        $b[$k] = strtotime($v[$subkey]);
        }
    asort($b);
    foreach($b as $key=>$val) {
        $c[] = $a[$key];
    }
    return $c;

对于希望在此处查看完整工作代码的用户，它是：

function removeSessionsFromSchedule($schedule,$remove){

    $modified = false;

    if(is_array($schedule) && count($schedule) > 0 && is_array($remove)  && count($remove) > 1) {

       if($modified) {
                break;
            }

       $pos = 0;
            $countdispo = count($dispo); 

        foreach($schedule as $s => $dispo) {
            $pos = 0;
            $countdispo = count($dispo);
            foreach($dispo as  $d) {
                $abs = $remove[$s];
                $counter = 0;
                // dispo debut/end
                $dis_s = strtotime($d['heure_debut']);
                $dis_e = strtotime($d['heure_fin']);

    else {$modified = false;}


    if($modified) {
        $schedule = removeSessionsFromSchedule($schedule,$remove);  
    }

    return $schedule;  
}

帮助者：

  function mergeSessionFromSchedule($schedule ,$seances) {

    $sessions = removeSessionsFromSchedule($schedule,$seances);

    $mergedSessions = array_merge_recursive($sessions , $seances);

    foreach($mergedSessions as $s => $val) {
        $sortedSessions[$s] = subval_sort_by_time($val,'heure_debut'); 
    }



    return $sortedSessions ;
   }

    function subval_sort_by_time($a,$subkey) {
        foreach($a as $k=>$v) {
        $b[$k] = strtotime($v[$subkey]);
        }
    asort($b);
    foreach($b as $key=>$val) {
        $c[] = $a[$key];
    }
    return $c;
