Question

我有一个以这种方式组织的小时列表：

Array (
    [0] => Array (
        [0] => 08:30
        [1] => 09:00
        [2] => 09:30
        [3] => 10:00
        [4] => 14:30
        [5] => 15:00
        [6] => 15:30
        [7] => 16:00
        [8] => 16:30
    )
    [1] => Array (
        [0] => 13:30
        [1] => 14:00
        [2] => 14:30
        [3] => 18:00
        [4] => 18:30
        [5] => 19:00
    )
)

我试图将它们转换为这种格式：

'0': [['08:30','10:00'], ['14:30', '16:30']],
'1': [['13:30','14:30'], ['18:00', '19:00']]

jQuery插件正在使用（Day Schedule Selector）。

如果时差大于：30分钟，则范围包含在方括号之间。

我无法在PHP中找到这样的解决方案。

以下是我尝试的内容：

$prepared = '';
foreach($serialized as $day=>$hours) {
    $prepared_hours = array();
    foreach($hours as $hour) {
        $prepared_hours[] = "['". $hour ."']"; 
    }
    $prepared .= "'{$day}' : [". implode(',', $prepared_hours) ."],\n";
}

但结果是：

'0' : [['08:30'],['09:00'],['09:30'],['10:00'],['14:30'],['15:00']‌,['15:30'],['16:00']‌,['16:30']], 
'1' : [['13:30'],['14:00'],['14:30'],['18:00'],['18:30'],['19:00']

我无法定义时间范围：[＆＃39; 08：30＆＃39;，＆＃39; 10：00＆＃39;]，[＆＃39; ..

我真的很感激任何帮助。

谢谢。

Answer 1

这将为您（Demo）执行此操作：

$array=array (
    0 => array (
        0 => "08:30",
        1 => "09:00",
        2 => "09:30",
        3 => "10:00",
        4 => "14:30",
        5 => "15:00",
        6 => "15:30",
        7 => "16:00",
        8 => "16:30"
    ),
    1 => array (
        0 => "13:30",
        1 => "14:00",
        2 => "14:30",
        3 => "18:00",
        4 => "18:30",
        5 => "19:00"
    )
);
foreach($array as $index=>$times){
    $prev="";
    $x=-1;
    foreach($times as $time){
        if(!$prev || $time!=date("H:i",strtotime("+30 minutes $prev"))){
            ++$x;
            $result[$index][$x]=array($time,$time);  // store new time as start & end 
        }else{
            $result[$index][$x][1]=$time;  // update end time
        }
        $prev=$time;
    }
}
echo "<pre>";
var_export($result);
echo "</pre>";

输出是按要求的：

array (
  0 => 
  array (
    0 => 
    array (
      0 => '08:30',
      1 => '10:00',
    ),
    1 => 
    array (
      0 => '14:30',
      1 => '16:30',
    ),
  ),
  1 => 
  array (
    0 => 
    array (
      0 => '13:30',
      1 => '14:30',
    ),
    1 => 
    array (
      0 => '18:00',
      1 => '19:00',
    ),
  ),
)

Answer 2

也许这会让你开始：

$start = new \DateTime('9:00');
$end = new \DateTime('14:00');
$period = new \DatePeriod($start,new \DateInterval('PT30M'),$end);

foreach ($period as $date) {
    print $date->format('H:i') . '<br>';
}

如何在PHP中定义时间范围？
