decode json format data sent via url

consider the following url

index.php?json={uid:guest|10001441}

I am not able to decode the data . I need the output as {"uid":"guest|10001441"}.

The code i m using is 

if (isset($_GET['json']))
{
   $url_data = $_GET['json'];
   $decoded_data = json_decode($url_data,true);
   var_dump($decoded_data);
}

But it gives me output as NULL. What am i doing wrong?? Do i need to pass data in a different format??

If you pass it like this it will work: ?json={"uid":"guest|10001441"}

But I am not sure whether it is a proper method.

It seems impossible to decode a JSON string without double quotes, as it's hard to determine whether a JSON string "{A:B:C}" is encoded from {"A":"B:C"} or from {"A:B":"C"}

You can use urlencode() to encode the JSON string or just ignore the extreme cases and add the double quotes manually to make the JSON string valid, hope this help :D

you can encode url parameter with base64_encode()

$json=base64_encode('{"uid":"guest|10001441"}');

url will look like this

index.php?json=eyJ1aWQiOiJndWVzdHwxMDAwMTQ0MSJ9

then do like this :-

if (isset($_GET['json']))
{
   $url_data = base64_decode($_GET['json']);
   $decoded_data = json_decode($url_data,true);
   var_dump($decoded_data);
}

The JSON you have in your URL is not valid. PHP's json_decode looks for double quotes around the uid and it's value.

EDIT: Rather than storing the data in the URL as json could you not store the data as key value pairs such as

?uid=value

And then you could do something like

$data = json_encode( $_GET );

The data you're passing is not valid JSON. It doesn't have double quotes around it currently. Try this:

if (isset($_GET['json']))
{
   $url_data = '"'.$_GET['json'].'"';
   $decoded_data = json_decode($url_data,true);
   var_dump($decoded_data);
}

Output:

string(20) "{uid:guest|10001441}"

Also, I'd suggest using POST instead of GET here.
