Question

我必须得到一个普通数组，按时间间隔分组创建一个多维数组。

原始数组是这样的：

$one = {
  0 => [
    'nome' => 'ALO/MANO'
    'origem' => 'GRU'
    'voo' => '4730'
    'inicio' => '2018/03/10'
    'hora' => '18:15'
   ],
  1 => [
   'nome' => 'JOHN/DOE'
   'origem' => 'GRU'
   'voo' => '4730'
   'inicio' => '2018/03/10'
   'hora' => '18:15'
  ], 
  2 => [
   'nome' => 'EVA/DOE'
   'origem' => 'GRU'
   'voo' => '4730'
   'inicio' => '2018/03/10'
   'hora' => '18:15'
  ], 
  3 => [
   'nome' => 'CARL/DOE'
   'origem' => 'GRU'
   'voo' => '4730'
   'inicio' => '2018/03/10'
   'hora' => '20:35'
  ], 
  4 => [
   'nome' => 'CARL/DOE'
   'origem' => 'GRU'
   'voo' => '4730'
   'inicio' => '2018/03/10'
   'hora' => '20:55'
  ], 
  5 => [
   'nome' => 'CARL/DOE'
   'origem' => 'GRU'
   'voo' => '4730'
   'inicio' => '2018/03/10'
   'hora' => '22:35'
  ], 
  46 => [
   'nome' => 'CARL/DOE'
   'origem' => 'GRU'
   'voo' => '4730'
   'inicio' => '2018/03/10'
   'hora' => '22:55'
  ], 
 };

我必须通过创建一个按hora键分组的函数来实现这一点：$ result = groupByTime（$ one，50）;

$result = {
 0 => [
   0 => [
    'nome' => 'ALO/RAFAEL'
    'origem' => 'GRU'
    'voo' => '4730'
    'inicio' => '2018/03/10'
    'hora' => '18:15'
  ],
  1 => [
   'nome' => 'JOHN/DOE'
   'origem' => 'GRU'
   'voo' => '4730'
   'inicio' => '2018/03/10'
   'hora' => '18:15'
  ], 
  2 => [
   'nome' => 'EVA/DOE'
   'origem' => 'GRU'
   'voo' => '4730'
   'inicio' => '2018/03/10'
   'hora' => '18:15'
  ] 
], 
1 => [
 0 => [
  'nome' => 'CARL/DOE'
  'origem' => 'GRU'
  'voo' => '4730'
  'inicio' => '2018/03/10'
  'hora' => '20:35'
 ], 
 1 => [
  'nome' => 'CARL/DOE'
  'origem' => 'GRU'
  'voo' => '4730'
  'inicio' => '2018/03/10'
  'hora' => '20:55'
 ], 
 2 => [
  'nome' => 'CARL/DOE'
  'origem' => 'GRU'
  'voo' => '4730'
  'inicio' => '2018/03/10'
  'hora' => '22:35'
 ] 
], 
0 => [
 0 => [
  'nome' => 'CARL/DOE'
  'origem' => 'GRU'
  'voo' => '4730'
  'inicio' => '2018/03/10'
  'hora' => '22:55'
 ]
],  
};

我已经尝试了几天，但似乎我被卡住了！

我认为这就是你要找的东西

/**
 * Group Elements Of One Array By Hora
 * @param array $arr
 * @return array 
 */
function groupByTimeInterval( $arr )
{
    $indexs = [];
    $new_arr = [];
    foreach ( $arr as $value ) {
        !isset( $indexs[$value['hora']] ) && $indexs[$value['hora']] = count($new_arr);
        $new_arr[$indexs[$value['hora']]][] = $value;
    }
    return $new_arr;
}

我使用给定的数组测试了它，我得到了以下结果：

[0] => Array
    (
        [0] => Array
            (
                [nome] => ALO/MANO
                [origem] => GRU
                [voo] => 4730
                [inicio] => 2018/03/10
                [hora] => 18:15
            )

        [1] => Array
            (
                [nome] => JOHN/DOE
                [origem] => GRU
                [voo] => 4730
                [inicio] => 2018/03/10
                [hora] => 18:15
            )

        [2] => Array
            (
                [nome] => EVA/DOE
                [origem] => GRU
                [voo] => 4730
                [inicio] => 2018/03/10
                [hora] => 18:15
            )

    )

[1] => Array
    (
        [0] => Array
            (
                [nome] => CARL/DOE
                [origem] => GRU
                [voo] => 4730
                [inicio] => 2018/03/10
                [hora] => 20:35
            )

    )

[2] => Array
    (
        [0] => Array
            (
                [nome] => CARL/DOE
                [origem] => GRU
                [voo] => 4730
                [inicio] => 2018/03/10
                [hora] => 20:55
            )

 ...
