PHP curl PUT does not continue respectively send payload/data - php

Question

I need to PUT some json data to an API endpoint, which works as expected via command line curl, but not via php curl and I don't have any idea, why it doesn't.
my command is
curl -v --insecure --request PUT --url <https://blabla/blablabla> --user 'username:password' --header 'Content-Type: application/json' --data '<valid json data>'
but it doesn't work this way within php:
// get cURL resource
$curl = curl_init();
// set cURL options
$curloptions = array(
CURLOPT_PUT => true, // set method to PUT
CURLOPT_RETURNTRANSFER => true, // return the transfer as a string
CURLOPT_VERBOSE => true, // output verbose information
CURLOPT_SSL_VERIFYHOST => false, // ignore self signed certificates
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_USERNAME => $config['uag']['user'], // set username
CURLOPT_PASSWORD => $config['uag']['pass'], // set password
CURLOPT_HTTPHEADER => array( // set headers
"Content-Type: application/json",
),
CURLOPT_POSTFIELDS => $jsondata // set data to post / put
);
curl_setopt_array($curl, $curloptions);
foreach($serverurilist as $uri) {
// set url
curl_setopt($curl, CURLOPT_URL, $uri);
// send the request and save response to $response
$response = curl_exec($curl);
// stop if fails
if(!$response) {
die('Error: "' . curl_error($curl) . '" - Code: ' . curl_errno($curl));
}
var_dump($response);
}
// close curl resource to free up system resources
curl_close($curl);
What doesn't work? The payload / data doesn't get submitted. If I tcpdump the command line und php version without encryption, I can see, that the command line submits the data right after the Expect: 100-continue request and the HTTP/1.1 100 Continue response from the server. The php version doesn't do anything after the HTTP/1.1 100 Continue response and quits after reaching the timeout.

From documentation:
CURLOPT_PUT - true to HTTP PUT a file. The file to PUT must be set with CURLOPT_INFILE and CURLOPT_INFILESIZE.
and you are not using any file to provide content.
You should use CURLOPT_CUSTOMREQUEST => 'PUT'.
This is your same cUrl request exported from Postman:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => 'https://blabla/blablabla',
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => '',
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => 'PUT',
CURLOPT_POSTFIELDS =>'<valid json data>',
CURLOPT_HTTPHEADER => [
'Content-Type: application/json',
'Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ='
],
));
$response = curl_exec($curl);
curl_close($curl);
echo $response;

You should use this CURLOPT_CUSTOMREQUEST=>'PUT'
