如何在使用PHP解析之前将其转换为有效的JSON？？？

我认为正确的JSON字符串也需要在所有键名周围加上双引号。您显示的是一个有效的JavaScript对象，但是当字符串化为JSON时，所有键周围都应该有双引号。

all（preOpen，preClose，…）必须是字符串，因此它们周围需要双引号

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

$sValidJson = preg_replace("/([{,])([a-zA-Z][^: ]+):/", "$1\"$2\":", $sInvalidJson);

如果有无效的Json字符串，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);

也看到这个

（此脚本仅适用于上面描述的无效JSON，否则必须更改模式。）

此外，还需要引用属性名称。

。有关示例，请参见。我将更改服务器以生成正确的JSON

它应该产生类似于

{
“预开放”：“900”，
....
}

是的，格式不正确-缺少关键字名称周围的引号。您需要自己将其解析为字符串。。。或更改服务器上的文件。

提供的大多数解决方案都有许多问题，主要是冒号问题

我编写了一个json-to-array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_解码之前将其删除

以下是函数：

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);
}

到目前为止，它看起来是防弹的

如果你发现了一个洞，请告诉我。

钥匙必须用双引号引起来-因此，preOpen：“900”必须是“preOpen”：“900”，依此类推。如果您无法控制json源代码，则不确定如何修复它。您可以使用regex-在冒号前查找一个单词并将其包含在双引号中。是的，通过使用

JSON.stringify（eval（{preOpen:'900'，..}））

，将返回有效的JSON@然而，Sandy505使用eval是危险的，尤其是当数据来自第三方来源时，因为您不知道可以传递什么。它也可能是恶意代码注入你的网页。不管怎么说，这不是PHP方面。回答得很好。工作非常好，除了部分时间：2012年1月11日12:32:14“，这是一个错误。我使用以下代码没有成功：`$url=''$session=curl_init（$url）；curl_setopt（$session，CURLOPT_USERAGENT，'Mozilla/5.0（Windows；U；Windows NT 5.1；en-US；rv:1.8.1.13）Gecko/20080311 Firefox/2.0.0.13'）；curl_setopt（$session，CURLOPT_POST，true）；curl_setopt（$session，CURLOPT_头，false）；curl_setopt（$session，CURLOPT_RETURNTRANSFER，true）$json=curl_exec（$session）；echo$json；回声“

”$sValidJson=preg_replace（“/（\n[\t]*）（[^\t]+）：/”、“$1\”、“$2\”：”、$json）；echo$sValidJson；`我得到了相同的输出！！！！我认为json有点不同（例如换行符），那么模式就不起作用了。我需要的正是json-string的内容。您真的需要转换字符串吗？如果只需要将json字符串添加到javascript输出，则不需要转换它，因为这是有效的javascript代码。否则，如果您想在PHP中解码json，您真的应该这样做。然后我需要字符串。这是我需要解析json的链接。我需要在我的php文件中解码这个json。
