Yes. As you insisted in a previous posting that the examples serve as documentation,
I tacitly adopted this terminology.

reading file hamlet.xml ...
hamlet.xml
storing document to collection /db/may ...
Ok.

and then it is accessible in the database.

It was the response when I used the httpclient class (created by the output
routines from your test_http_soap example).
 
In the meantime, a small part of the problem is solved:
we found out that the server ignores the content type
declaration when it is not exactly "text/xml" (but extended with parameters).

But, after fixing this, I am still back with the original question: how
to do PUT with HTTP with any PHP class. Writing the XML in the body (as in your
SOAP example) as

  $http=new http_class;
  $url="http://ap34.ifi.informatik.uni-goettingen.de:8081/exist/servlet/db/may/bla.xml";
  $http->GetRequestArguments($url,$arguments);
  $arguments["RequestMethod"]="PUT";
  $arguments["Headers"]["Content-Type"]="text/xml";
  $arguments["Body"]="<?xml version='1.0' encoding='UTF-8'?><name>bla</name>";

does not work:

http/1.1 400 parsing+exception%3a+premature+end+of+file%2e:

Even if I add an explicit attribute for the content length,
 $arguments["Headers"]["Content-length"]=54;
(or instead of 54 any number like 3 or 1000), it waits for some time and returns

http/1.1 500 read+timed+out:
