Upload a file using an API PUT request

I'm building an API in PHP. One of the methods is place.new (PUT request). It expects several string fields, and it also expects an image. However I can't get it working. With a POST request it was easy, but I'm not sure how to do it with a PUT and how to get the data on the server.

thanks for the help!

Test CURL code

$curl = curl_init();
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($curl, CURLOPT_URL, $this->url);

curl_setopt($curl, CURLOPT_PUT, 1);
curl_setopt($curl, CURLOPT_INFILE, $image);
curl_setopt($curl, CURLOPT_INFILESIZE, filesize($image));

$this->result = curl_exec($curl);
curl_close($curl); 

Server code

if ( $im_s = file_get_contents('php://input') )
{
    $image = imagecreatefromstring($im_s);

    if ( $image != '' )
    {
        $filename = sha1($title.rand(11111, 99999)).'.jpg';
        $photo_url = $temp_dir . $filename;
        imagejpeg($image, $photo_url);

        // upload image
        ...
    }
}

Solution

send

// Correct: /Users/john/Sites/....
// Incorrect: http://localhost/...
$image = fopen($file_on_dir_not_url, "rb");

$curl = curl_init();
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($curl, CURLOPT_URL, $url);

curl_setopt($curl, CURLOPT_PUT, 1);
curl_setopt($curl, CURLOPT_INFILE, $image);
curl_setopt($curl, CURLOPT_INFILESIZE, filesize($file_on_dir_not_url));

$result = curl_exec($curl);
curl_close($curl); 

receive

/* Added to clarify, per comments */
$putdata = fopen("php://input", "r");

/* Open a file for writing */
$fp = fopen($photo_url, "w");

/* Read the data 1 KB at a time
    and write to the file */
while ($data = fread($putdata, 1024))
{
    fwrite($fp, $data);
}

/* Close the streams */
fclose($fp);
fclose($putdata);

PHP doesn't populate form data in PUT requests (either in PATCH).

Just install https://pecl.php.net/package/apfd and PATCH and PUT request will have $_POST and $_FILES as if were GET or POST requests.

In Docker it will be:

RUN pecl install --force apfd && rm -rf /tmp/pear && docker-php-ext-enable apfd

Did you read http://php.net/manual/en/features.file-upload.put-method.php ? Script PUT /put.php all set up?

Also, what is $image -- it needs to be a file handler, not a file name.

Ps. Using file_get_contents will try to load whatever is PUT on the server into memory. Not a good idea. See the linked manual page.
