Parsing JSON POST PHP, unable to generate object

Question

I've done this many times before with various SAAS services, but I can't parse the supposedly JSON responses I'm getting from Blitline image processing's API.

Here's what I do to handle the POST:

$body=@file_get_contents('php://input');

print_r($body); 

results=%7B%22original_meta%22%3A%7B%22width

OR

$body=rawurldecode($body);

print_r($body); 

results={"original_meta":{"width ...

When I go to print $body->original_meta->width, I get an empty string. You'll realize I didn't json_decode() the $body but that's because that returns an empty string too.

Removing the results= with substr($body, 8) doesn't help either.

Can anyone help?

Why don't you start by removing the error suppression and see if that does anything — steven

I don't understand your code blocks...is "results=" part of your code? Or is that the response? If the latter, is "results=" part of the response, or is that just your way of showing us what the code resulted in? — JAAulde

It looks like you are perhaps getting not getting a JSON string POSTed to the script, but rather a query string with parameter results with a URL-encoded JSON string value. Perhaps in this case you should actually be getting your value from $_POST (that is of course if request is coming in with form-encoded content type header. — Mike Brant

Why are you dealing with the raw post? Seems you just want $data = json_decode($_POST['results']). — MrCode

I was just going to say it would make sense to deal with $_POST instead of reading input. — JAAulde

Expanding on my comment: the POST data is standard x-www-form-urlencoded data so there's no need to access the raw POST data. You can simply access the $_POST array that contains the URL decoded data:

$data = json_decode($_POST['results']);
echo $data->original_meta->width;

Ok this is pretty ugly but it works...

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

$body=rawurldecode($body);

$body=substr($body, 8); 

$body=json_decode($body);

echo $body->original_meta->width; //1936

I think another option would be to use parse_str($body, $data); json_decode($data['results']);.
