求助，PHP处理三维数组

Question

原始数组： $arr = Array( '11' => Array( '1' => Array( 'sortid' => '6', 'driverid' => '1003', 'carsid' => '11', 'lineid' => '2', 'gettime' => '2018-01-19 10:00:00', 'comments' => '' ), '2' => Array( 'sortid' => '2', 'driverid' => '1000', 'carsid' => '11', 'lineid' => '1', 'gettime' => '2018-01-19 10:03:31', 'comments' => '' ), '4' => Array( 'sortid' => '9', 'driverid' => '1001', 'carsid' => '11', 'lineid' => '5', 'gettime' => '2018-01-19 12:48:54', 'comments' => '' ), '6' => Array( 'sortid' => '4', 'driverid' => '1001', 'carsid' => '11', 'lineid' => '2', 'gettime' => '2018-01-19 14:47:50', 'comments' => '' ), '7' => Array( 'sortid' => '5', 'driverid' => '1001', 'carsid' => '11', 'lineid' => '2', 'gettime' => '2018-01-19 14:48:07', 'comments' => '' ), '8' => Array( 'sortid' => '7', 'driverid' => '1006', 'carsid' => '11', 'lineid' => '5', 'gettime' => '2018-01-19 14:48:29', 'comments' => '' ), '10' => Array( 'sortid' => '10', 'driverid' => '1003', 'carsid' => '11', 'lineid' => '5', 'gettime' => '2018-01-19 14:49:05', 'comments' => '' ), ), '10' => Array( '3' => Array( 'sortid' => '1', 'driverid' => '1000', 'carsid' => '10', 'lineid' => '1', 'gettime' => '2018-01-19 11:47:15', 'comments' => '' ), '5' => Array( 'sortid' => '3', 'driverid' => '1000', 'carsid' => '10', 'lineid' => '1', 'gettime' => '2018-01-19 14:47:40', 'comments' => '' ), '12' => Array( 'sortid' => '12', 'driverid' => '1001', 'carsid' => '10', 'lineid' => '1', 'gettime' => '2018-01-19 14:49:17', 'comments' => '' ), ), '12' => Array( '9' => Array( 'sortid' => '8', 'driverid' => '1001', 'carsid' => '12', 'lineid' => '5', 'gettime' => '2018-01-19 14:48:46', 'comments' => '' ), '11' => Array( 'sortid' => '11', 'driverid' => '1006', 'carsid' => '12', 'lineid' => '1', 'gettime' => '2018-01-19 14:49:12', 'comments' => '' ), ), '13' => Array( '13' => Array( 'sortid' => '13', 'driverid' => '1001', 'carsid' => '12', 'lineid' => '5', 'gettime' => '2018-01-19 12:48:46', 'comments' => '' ), '14' => Array( 'sortid' => '14', 'driverid' => '1006', 'carsid' => '12', 'lineid' => '1', 'gettime' => '2018-01-19 14:49:12', 'comments' => '' ), ), ); 三维数组的要求是：三位数组的第三位维的相邻的gettime键值的差如果大于600秒，就返回其sortid键的值。处理后的数组如下： $arrs = array( '11' => array( array(6,2), array(4,5,7,10), ), '10' => array( array(3,12), ), '12' => array( array(8,11) ), ); 多谢各位大牛！

Answer 1

[1]保留key
$aDelArr = [];
foreach($arr as $key => $aFValue)
{
    $i = 0;
    $iPreTime = 0;
    foreach($aFValue as $iNode => $aV)
    {
        $iTime = strtotime($aV['gettime']);
        $iSubTime = $iTime - $iPreTime;
        if($iSubTime > 600 && !empty($aDelArr[$key][$i]))
        {
            $i++;
        }
        $aDelArr[$key][$i][$iNode] = $aV['sortid'];
        $iPreTime = $iTime;
    }
}
[2]修改原数组
foreach($arr as $key => &$aValue)
{
    $aTemp = [];
    $iPreTime = 0;
    foreach($aValue as $aV)
    {
        $iTime = strtotime($aV['gettime']);
        $iSubTime = $iTime - $iPreTime;
        if($iSubTime > 600)
        {
            $aTemp[] = [];
        }
        $aTemp[count($aTemp) - 1][] = $aV['sortid'];
        $iPreTime = $iTime;
    }
    $aValue = $aTemp;
}

Answer 2

看了要求和结果，怎么好像不太对，为什么不是'10'=>array( array(1,3))

Answer 3

首先遍历一下这个三维数组，在循环中判断相邻gettime键值的差,如果大于600秒，最后返回sortid键的值,就是这三个点，第二个比较难点.
