PHP encountering a bad escaped character while parsing JSON using JSON.parse

Question

PHP encountering a bad escaped character while parsing JSON using JSON.parse

I'm encountering an issue with JSON parsing. In my PHP code, I have the following:

 json_encode(getTeams(),JSON_HEX_APOS);

This returns a large amount of data.

Sample data: To provide more clarity, let's assume I have this:

my_encoded_data = 
     {
        "13": "Germany-1",
        ...
        "68": "C. Oberstolz/P. Gruber"
    }

To validate the data, I split it into smaller parts and checked it using JSONLint, where it was confirmed as valid JSON. Next, I assigned it in JavaScript like so:

window.objteamsFromServer  = my_encoded_data;

Then, when attempting to parse it in JSON:

arrSearch = window.objteamsFromServer;

It throws this error:

JSON.parse: bad escaped character

How can I resolve this issue?

Please let me know if any additional information is required.

Thank you,
Awlad

It seems like you might be having trouble understanding what exactly my_encoded_data represents based on your question. It sounds like you are taking the output of json_encode and using it within JavaScript source code, such as:

window.objteamsFromServer = {
    "13": "Germany-1",
    "14": "Russia-1",
    "15": "Switzerland-1",
    "16": "Canada-1",
    "17": "USA-1",
    // ...and so forth
};

Additionally, it seems like you are attempting to parse this data again using JSON.parse.

However, this is not necessary. The JavaScript engine will have already interpreted the object initializer (as it is JavaScript source code, not JSON), so you can access the values directly like this:

console.log(window.objteamsFromServer[13]); // "Germany-1"

It seems that the error you're experiencing might be related to this specific line:

"43": "A. Florschütz/T. Wustlich",

Take note of the special character 'ü' in the name mentioned above.

One potential solution is to encode the data on the server side and then decode it on the client side. You can use JavaScript's decodeURIComponent function for decoding on the client side.

To learn more about server-side encoding of data, you can refer to the PHP documentation.
