Is it possible to create a Restful webservice with POST requests in PHP without using any library?

Question

Basic requirement is to know if we can iterate through $_POST when the request body payload has data sent in json format e.g.

{"City":{"countryCode": "IN","regionCode":"KR"}}

We are able to access this only if we send the data as

m={"City":{"countryCode": "IN","regionCode":"KR"}}

We are able to access this using $_POST['m'] The Content-Type is set to default application/x-www-form-urlencoded, when we set this as application/json $_POST is empty/null.

If we try to access this as $_POST instead of $_POST['m'] it returns null/empty.

NB: I am newbie to PHP. Is it possible to create webservices without any library. Without making use of any library can PHP accept the post request with json data.

Answer 1

To get raw POST data (as opposed to having to access individual POST variables such as $_POST['m']), you can use the following wrapper:

$json = file_get_contents('php://input');

You can read the manual on wrappers if you're interested in learning a bit more about them.

Answer 2

This is how i am getting data and saving it to my database.

 $return    = array();
 $data      = json_decode(stripslashes($_REQUEST['Data']));

 $email     = $data->{"paramA"};
 $password      = $data->{"paramB"};

i think it might help you.
