PHP：如何将此数组拆分为两个单独的数组或值？

我希望能够将这两个值拉成两个单独的值，例如，“1519106711000”和“1008.48”、日期和速率。

给您：

{"cae7fc":
["1519106711000 1008.48","1519107011000 1000.28","1519107311000 1009.89","1519107611000 1000","1519107910000 1006.52","1519108211000 985.68","1519108511000 1009.16","1519108812000 1003.5","1519109111000 998.09"]}

---

您可以使用以下

regex

和

preg\u match\u all

来实现您的目标

$json = json_decode('["1519106711000 1008.48","1519107011000 1000.28","1519107311000 1009.89","1519107611000 1000","1519107910000 1006.52","1519108211000 985.68","1519108511000 1009.16","1519108812000 1003.5","1519109111000 998.09"]');

$data = [];
foreach ($json as $row) {
    $row = explode(' ', $row);
    $data[] = ['date' => $row[0], 'rate' => $row[1]];
}

// you can use $data however you want
// it will give you something like this :
/*
[{"date":"1519106711000","rate":"1008.48"},{"date":"1519107011000","rate":"1000.28"},{"date":"1519107311000","rate":"1009.89"},{"date":"1519107611000","rate":"1000"},{"date":"1519107910000","rate":"1006.52"},{"date":"1519108211000","rate":"985.68"},{"date":"1519108511000","rate":"1009.16"},{"date":"1519108812000","rate":"1003.5"},{"date":"1519109111000","rate":"998.09"}]
*/

$rate

$json='{  
   "cae7fc":[  
      "1519106711000 1008.48",
      "1519107011000 1000.28",
      "1519107311000 1009.89",
      "1519107611000 1000",
      "1519107910000 1006.52",
      "1519108211000 985.68",
      "1519108511000 1009.16",
      "1519108812000 1003.5",
      "1519109111000 998.09"
   ]
}';

preg_match_all('/(?<=")\d+/', $json, $date);
preg_match_all('/[\d\.]+(?=")/', $json, $rate);

Array
(
    [0] => Array
        (
            [0] => 1519106711000
            [1] => 1519107011000
            [2] => 1519107311000
            [3] => 1519107611000
            [4] => 1519107910000
            [5] => 1519108211000
            [6] => 1519108511000
            [7] => 1519108812000
            [8] => 1519109111000
        )

)

要解决该问题，您可以使用以下功能：

• 分解

• sscanf

• preg\u match

• preg_split

使用

sscanf

的示例：

Array
(
    [0] => Array
        (
            [0] => 1008.48
            [1] => 1000.28
            [2] => 1009.89
            [3] => 1000
            [4] => 1006.52
            [5] => 985.68
            [6] => 1009.16
            [7] => 1003.5
            [8] => 998.09
        )

)

按空格分解。请尝试对每个

“cae7fc”

数组元素按空格使用

分解（）。Explode无法工作，因为php抛出“Explode（）期望参数2为字符串，数组给定”错误。@Alberter yes这是一个预期错误，因为
Explode（）
返回数组，所以您必须通过索引访问它，请检查我的soluHesham，谢谢您的帮助。你太棒了！不幸的是，我提供的字符串已经通过json_decode（）运行了；json_decode（）；包括“cae7fc”元素。@albertR然后，您可以使用
foreach（$json['cae7fc']作为$row）
团队，这两种解决方案的组合似乎可以工作。谢谢你的帮助，也谢谢你花时间帮忙。干杯请解释您建议的代码以及它应该如何帮助您。顺致敬意，
