解析 json 由于 unicode 个字符和斜杠而损坏的字符串

Question

I'm trying to received data from Android to Laravel using API. Below are the data that I received in format object array list.

$obj = '{ "registerDetails": "{"accountName":"hh h hc","accountNumber":"868686","addressUser":"cg h jc","bankId":1,"selectedCityId":1,"emergencyName":"g g h","emergencyNumber":"0686868","education":[{"certificatePicture":{"body":{},"headers":{"namesAndValues":["Content-Disposition","form-data; name\u003d\"certificateFile\"; filename\u003d\"2022-11-30-00-56-28-598.jpeg\""]}},"grade":"hxycucu","educationLvl":"STPM / A Level or Equivalent","endEducation":"Dec 2022","id":4,"institutionName":"yxyxyxy","isEducationExpandable":false,"startEducation":"Nov 2022"}],"skill":[{"id":8},{"id":10}],"work":[{"companyName":"cuvuv","jobEndDate":"Nov 2022","isCurrentlyWorkHere":true,"isJobExpand":true,"jobPosition":"g cuc","jobScope":"cuccu","jobTitle":"6ff7f","jobStartDate":"Oct 2022"}],"phoneUser":"906886","postCode":"058686","selectedStateId":1}", "myKadFile": {}, "selfieFile": {} }';

I already attempted to decode the object, but it returned NULL .

Here's what I tried:

var_dump(json_decode($obj, true));

Answer 1

Bruteforce trial and error json repair at its finest:

The problem stems from those pesky unicode = ( = ) characters.

I needed to replace them and handle slashes.

_{...In case I need to clarify for anyone...}

THIS IS A HACK!!!!

Code: ( Demo )

$fixed = preg_replace('/\\\\u003d\\\\\\\\(.*?)\\\\\\\\/', '=\\\\\\\\\\\\$1\\\\\\\\\\\\', $obj);

var_export(
    json_decode(json_decode($fixed)->registerDetails)
);

Output:
