不带索引的son数组

Question

我有这段代码，主要是取一些行，放入一个4行一组的数组中

最初，数据的格式如下：

line1
line2
line3
line4
line5
line6
line7
line8

使用下面的代码，我将行传递给array：

$addresses = [];
foreach (preg_split("/((\r?\n)|(\r\n?))/", $nodes) as $line) {
    $temp[] = trim($line);
    if(count($temp) == 4){
        array_push($addresses,[
                    'ADDRESS' => $temp[0],
                    'STREET_NAME' => $temp[1],
                    'TOWN_NAME' => $temp[2],
                    'POST_CODE' => $temp[3]
                ]);
      $temp = [];
  }
}
var_dump(json_encode($addresses,JSON_PRETTY_PRINT));

但结果不是我想要的.：

{
  "1": {
      "ADDRESS": "10",
      "STREET_NAME": "TRIQ ID-DAR TA` PULTU",
      "TOWN_NAME": "BIRZEBBUGA",
      "POST_CODE": "BBG 1810"
  },
  "2": {
      "ADDRESS": "12",
      "STREET_NAME": "TRIQ ID-DAR TA` PULTU",
      "TOWN_NAME": "BIRZEBBUGA",
      "POST_CODE": "BBG 1810"
  }
}

我不想要索引..。

我需要这样的东西：

[
{
  "ADDRESS": "10",
  "STREET_NAME": "TRIQ ID-DAR TA` PULTU",
  "TOWN_NAME": "BIRZEBBUGA",
  "POST_CODE": "BBG 1810"
},
{
  "ADDRESS": "12",
  "STREET_NAME": "TRIQ ID-DAR TA` PULTU",
  "TOWN_NAME": "BIRZEBBUGA",
  "POST_CODE": "BBG 1810"
}
]

你知道这个错误吗？

Answer 1

这将创建您所要求的内容

$nodes = 'line1
line2
line3
line4
line5
line6
line7
line8
';

$addresses = [];
foreach (preg_split("/((\r?\n)|(\r\n?))/", $nodes) as $line) {
    $temp[] = trim($line);
    if(count($temp) == 4){
        $obj = new stdClass();
        $obj->ADDRESS =  $temp[0];
        $obj->STREET_NAME = $temp[1];
        $obj->TOWN_NAME = $temp[2];
        $obj->POST_CODE = $temp[3];

        $addresses[] = $obj;
        $temp = [];
    }
}
var_dump(json_encode($addresses,JSON_PRETTY_PRINT));

结果：

string(266) "[
    {
        "ADDRESS": "line1",
        "STREET_NAME": "line2",
        "TOWN_NAME": "line3",
        "POST_CODE": "line4"
    },
    {
        "ADDRESS": "line5",
        "STREET_NAME": "line6",
        "TOWN_NAME": "line7",
        "POST_CODE": "line8"
    }
]"

但是，当您查看编码后再解码为PHP数据类型的数据时，仍然会对对象进行数字索引，因为数组必须有索引。当您将此数据转换为javascript时，这适用于PHP和等效的javascript

print_r(json_decode(json_encode($addresses)));

结果

Array
(
    [0] => stdClass Object
        (
            [ADDRESS] => line1
            [STREET_NAME] => line2
            [TOWN_NAME] => line3
            [POST_CODE] => line4
        )

    [1] => stdClass Object
        (
            [ADDRESS] => line5
            [STREET_NAME] => line6
            [TOWN_NAME] => line7
            [POST_CODE] => line8
        )
