$data = file_get_contents("php://input");
$json = json_decode($data, true);
var_dump($json);// o/p->Null
print_r($json);// o/p-> nothing

echo $json[2];

In the request you put the json in a querystring var called json, therefor, shouldn't the json_decode be on $data['json'] rather than just $data? — Oldskool

allow_url_include may not be set to true in your php.ini? This is common on some older shared hosting services

Refer to this Stack Overflow post for a potential fix.

Ahhh... The problem is that you arent POSTing anything. But rather sending it via query string so there is no body for the stream to retrieve. So as I understand it you cannot use a streams to get the data

See PHP.net Aritical

"php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST request"

Well there are a couple of options. You can submit a form with your data in a form field and the form method type to POST. Or you can do it in PHP via cURL. Refer to - davidwalsh.name/curl-post - for more instructions on that.

if your site is https and we submit a POST request of content type JSON using a http url of the site, then you may get php://input as null.when submitting data to a https website using https could be better
