Question

— Question —

I am just starting out with the REST API and am getting pretty confused.

This is what my PHP cRUL client-side looks like for a PUT.

case 'PUT':
    curl_setopt($handle, CURLOPT_CUSTOMREQUEST, 'PUT');
    curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
    break;

Now when I look at the server my $_SERVER[‘REQUEST_METHOD’] shows PUT, but my question is how do I get the $data I sent with CURLOPT_POSTFIELDS.

All I need to do is get the $data sent with a PUT request into the next line. Like

$value = $data['curl_data'];

I have seen so much clutter on this topic that it is giving me a headache. It seems so easy on the php client side, but no one has answers that are working for the php server side.

Thanks for any help!

I am new so I can’t answer my own question until after 8 hours… odd 🙂

Okay, after working with the great people here I have to say we ran into the answer. I am kicking myself for it being so easy, at the same time it was confusing.

curl_setopt($handle, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($data));

The first change (above) I had to add http_build_query() around $data. This took my data from an array to a url friendly string.

Next up I had to add.

parse_str(file_get_contents('php://input'), $put);

Now I can do things like $put[‘data’].

The answer PaulPRO gave above does work to get the data the same way file_get_contents() did with less lines. We got stuck trying to figure out how to parse the data which was where my lack of http_build_query() I had seen on another site kicked into play.

So This is how it all works.

1. Data is put into a normal array.
2. http_build_query() converts it into a nice almost GET like string.
3. file_get_contents() transports it from the client to the server.
4. parse_str() then turns it back into an array.

I am seeing a lot of messages about using PUT to send files. I can see how this would work, but from what I read in this entire REST process was that PUT is to update data as post is to create data. Maybe I am mistaken. Am I missing something?

From the PHP Manual:

PUT data comes from stdin:

$putdatafp = fopen("php://input", "r");

Example usage:

$putfp = fopen('php://input', 'r');
$putdata = '';
while($data = fread($putfp, 1024))
    $putdata .= $data;
fclose($putfp);
