在 PHP 中将重复的一维数组转换为多维数组

Question

我有一个包含纬度、经度和时间数据的单维 PHP 数组。数据如 [lat, long, date, lat, long, date, lat, long, date.... 等等]

Array ( [0] => -28.0447606 [1] => 153.4340961 [2] => 1424136836118 [3] => -28.0447612 [4] => 153.4340963 [5] => 1424136876189 [6] => -28.0447658 [7] => 153.4340962 [8] => 1424136897993 [9] => -28.0447619 [10] => 153.4340615 [11] => 1424136918045 [12] => -28.0447656 [13] => 153.434057 [14] => 1424136938057 [15] => -28.0447613 [16] => 153.4340484 [17] => 1424136958085 [18] => -28.0447791 [19] => 153.4340959 [20] => 1424136978117 [21] => -28.0447584 [22] => 153.4340501 [23] => 1424136998135 [24] => -28.0447676 [25] => 153.434047 [26] => 1424137018179 [27] => -28.044782 [28] => 153.4340982 [29] => 1424137038185 [30] => -28.0447599 [31] => 153.4340496 [32] => 1424137058214 [33] => -28.0447614 [34] => 153.4340531 [35] => 1424137078589 [36] => -28.0447588 [37] => 153.4340963 [38] => 1424137098731 [39] => -28.0447768 [40] => 153.434098 [41] => 1424137138640 [42] => -28.0447141 [43] => 153.4341097 [44] => 1424137158672 [45] => -28.0447628 [46] => 153.4340962 [47] => 1424137178698 [48] => -28.0447622 [49] => 153.4340962 [50] => 1424137198726 [51] => -28.0447528 [52] => 153.4340936 [53] => 1424137218871 [54] => -28.0447636 [55] => 153.4340472 [56] => 1424137258825 [57] => -28.0447608 [58] => 153.434097 [59] => 1424137279945 [60] => -28.0447656 [61] => 153.4340979 [62] => 1424137300018 )

我只是想知道是否有一种简单的方法可以将其转换为二维数组，以便我可以像 $gps[0][1] 或 $gps[3][0] etc 那样访问它们。我已经尝试了一些方法，比如使用 for 循环，但肯定还有其他一些方法我忽略了。

如果我没记错的话这就是你想要的。您只需要更改变量的 $arr。

$coords = array_map(function($coords) {
  return array(
    "lat" => $coords[0],  # latitude
    "long" => $coords[1], # longitude
    "ts" => $coords[2]    # timestamp
  );
}, array_chunk($arr, 3));

/*
Array (
  Array (
    [lat] => 12
    [long] => 34
    [ts] => 56
  )
  Array (
    [lat] => 12
    [long] => 34
    [ts] => 56
  )
  ... and so on
)
*/
