将无效的json转换为有效的json
我正在尝试从Web服务器读取.json文件。 我从服务器收到的JSON报告在http://jsonlint.com/无效：

Parse error on line 1: { preOpen: "900", -----^ Expecting 'STRING', '}'
在使用PHPparsing之前，如何将它转换为VALID JSON？
所有的键 （preOpen，preClose，…）必须是string，所以他们需要双引号。
{ "preOpen": "900", "preClose": "908", ... }
===更新===
如果你有一个无效的JSONstring，你可以用下面的脚本来转换它：
$sInvalidJson = '{ preOpen: "900", preClose: "908" }'; $sValidJson = preg_replace("/(\n[\t ]*)([^\t ]+):/", "$1\"$2\":", $sInvalidJson);
也看到这个例子 。
（该脚本仅适用于上述无效的JSON，否则必须更改该模式。）
===更新===

另外这个更新的例子 。
提供的大多数解决scheme都有一些问题，主要是冒号。
我写了一个JSON数组函数，克服了这个问题。
它还检查jsonstring周围的圆括号，并在json_decode之前删除它。
这是function：
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，并将其从variables名称中排除。
这是我testing的一个示例string：
（{style：“border：5px solid pink;”，class：“test”，“correct”：“value”，test：true，var5：“some escaped \”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，它看起来是防弹的。
如果你发现一个洞，让我知道。
我相信正确的JSONstring也需要在所有键名称周围加双引号。 你所展示的是一个有效的JavaScript对象，但是当把string化成JSON时，所有的键都应该用双引号。
属性名称需要引用。 请参阅http://json.org/example.html 。 我会改变服务器产生适当的JSON。
它应该产生像{ "preOPen": "900", .... }
是的，这是错误的 – 缺less关键名称的引号。 你需要自己parsing它作为string…或更改服务器上的文件。
