如何在使用PHP解析之前将其转换为VALID JSON？

5 个答案:

答案 0 :(得分：9)

所有keys（preOpen，preClose，...）都必须是字符串，所以它们需要双引号。

{
    "preOpen": "900",
    "preClose": "908",
    ...
}

=== UPDATE ===

如果您的Json-String无效，可以使用以下脚本进行转换：

$sInvalidJson = '{
    preOpen: "900",
    preClose: "908"
}';
$sValidJson = preg_replace("/(\n[\t ]*)([^\t ]+):/", "$1\"$2\":", $sInvalidJson);

另见example。

（此脚本仅适用于上述无效JSON，否则必须更改模式。）

此updated example。

答案 1 :(得分：3)

我认为正确的JSON字符串也需要围绕所有键名称的双引号。你展示的是一个有效的JavaScript对象，但是当字符串化成JSON时，所有键都应该有双引号。

答案 2 :(得分：3)

提供的大多数解决方案都存在许多问题，主要是冒号。

我写了一个json到数组函数来克服这个问题。

它还检查json字符串周围的圆括号，并在json_decode之前删除它。

这是功能：

function jsonDecode($string, $assoc=true, $fixNames=true){
  if(strpos($string, '(') === 0){
    $string = substr($string, 1, strlen($string) - 2); // remove outer ( and )
  }
  if($fixNames){
    $string = preg_replace("/(?<!\"|'|\w)([a-zA-Z0-9_]+?)(?!\"|'|\w)\s?:/", "\"$1\":", $string);
  }
  return json_decode($string, $assoc);
}

它还检查冒号前的空格，并从变量名中排除它们。

这是我测试的示例字符串：

  

（{style：“border：5px solid pink;”，class：“test”，“correct”：“value”，   test：true，var5：“some escapeped”string“}）

转换后：

Array
(
    [style] => border: 5px solid pink;
    [class] => test
    [correct] => value
    [test] => 1
    [var5] => some escaped" string
)

到目前为止它看起来像防弹。

如果你发现了一个洞，请告诉我。

答案 3 :(得分：1)

是的，这是错误的 - 关键名称缺少引号。您需要自己将其解析为字符串...或更改服务器上的文件。

答案 4 :(得分：0)

需要引用属性名称。有关示例，请参阅http://json.org/example.html。我会更改服务器以生成适当的JSON。

它应该产生类似的东西  { "preOPen": "900", .... }
