我很困惑地将2个元素组合在数组中，这是输出：

array:16 [▼ // app\Http\Controllers\TappingController.php:18
  0 => "-3.6475644"
  1 => "114.8616161"
  2 => "-3.6475625"
  3 => "114.8613661"
  4 => "-3.6475798"
  5 => "114.8604937"
  6 => "-3.6475471"
  7 => "114.8596975"
  8 => "-3.6464274"
  9 => "114.8598053"
  10 => "-3.6449308"
  11 => "114.85987"
  12 => "-3.6439882"
  13 => "114.8599144"
  14 => "-3.6427097"
  15 => "114.8599408"
]

我想要这样的结果：

array:8 [▼ // app\Http\Controllers\TappingController.php:18
  0 => "-3.6475644,114.8616161"
  1 => "-3.6475625,114.8613661"
  2 => "-3.6475798,114.8604937"
  3 => "-3.6475471,114.8596975"
  4 => "-3.6464274,114.8598053"
  5 => "-3.6449308,114.85987"
  6 => "-3.6439882,114.8599144"
  7 => "-3.6427097,114.8599408"
]

怎么会得到这样的结果呢？

你可以通过循环遍历原始数组并将每两个元素连接成一个新数组来实现这一点。下面是一个示例代码片段：

$originalArray = [
    "-3.6475644",
    "114.8616161",
    "-3.6475625",
    "114.8613661",
    "-3.6475798",
    "114.8604937",
    "-3.6475471",
    "114.8596975",
    "-3.6464274",
    "114.8598053",
    "-3.6449308",
    "114.85987",
    "-3.6439882",
    "114.8599144",
    "-3.6427097",
    "114.8599408",
];

$newArray = [];

for ($i = 0; $i < count($originalArray); $i += 2) {
    $newArray[] = $originalArray[$i] . ',' . $originalArray[$i + 1];
}

print_r($newArray);

这将输出：

Array
(
    [0] => -3.6475644,114.8616161
    [1] => -3.6475625,114.8613661
    [2] => -3.6475798,114.8604937
    [3] => -3.6475471,114.8596975
    [4] => -3.6464274,114.8598053
    [5] => -3.6449308,114.85987
    [6] => -3.6439882,114.8599144
    [7] => -3.6427097,114.8599408
)

你可以使用array_map（）函数来合并数组中的两个元素：

$result = array_map(function($a, $b) {
    return $a . ',' . $b;
}, $array[0], $array[1]);
