JS JSON没有被PHP json_decode解析

I have an issue with parsing JSON data by json_decode PHP function. The issue is that the JSON I receive is not properly formatted. It looks as follows:

"{ user:1 ,product:4 ,commentCount: 1 ,comment:'All fine! Well done.' ,commentDate:{ year:2015 ,month:8 ,day:19 } , likes:8 }"

When I try to decode this string with json_decode PHP function I get NULL. Is it possible to properly format this string with a preg_replace function

EDIT: I found this code on the web but it only wraps the variable names in the quotes. The values are still as they were and json_decode still returns NULL.

// fix variable names
$PHPJSON = preg_replace( '/([a-zA-Z0-9_]+?):/' , '"$1":', $PHPJSON );

我在使用json_decode PHP函数解析JSON数据时遇到问题。 问题是我收到的JSON格式不正确。 它看起来如下:

 “{user:1,product:4,commentCount:1,comment:'一切都很好!干得好。'  ,commentDate:{year:2015,month:8,day:19},赞:8}“

当我尝试使用json_decode PHP函数解码此字符串时 我得到NULL。 是否可以使用preg_replace函数正确格式化此字符串

编辑: 我在网上找到了这段代码,但它只包装了 引号中的变量名。 这些值仍然是原样,json_decode仍然返回NULL。

 $ PHPJSON = preg_replace('/([a-zA-Z0-9_  ] +?):/','“$ 1”:',$ PHPJSON);

    Working solution for your malformed json:

    $json = "{ user:1 ,product:4 ,commentCount: 1 ,comment:'All fine! Well done.' ,commentDate:{ year:2015 ,month:8 ,day:19 } , likes:8 }";
    $json = preg_replace('/(,|\{)[ \t
    ]*(\w+)[ ]*:[ ]*/','$1"$2":',$json);
    $json = preg_replace('/":\'?([^\[\]\{\}]*?)\'?[ 

    But in general you need to wrap object param in double quotes "arg":1. Non-numeric values also. Just like this:


    The second function returns you id of an error, if there was any. Check the php manual for error codes identification
