"Its not in the PHP 5.3 release, rather its a bug in the Zend
AutoDiscover class"
If it works fine in 5.2(.6) but not in 5.3 then something changed in
5.3 that made things break, which suggests a bug in 5.3.
If adding a content-length header fixes things then that's great as a
quick-fix, but SoapServer should be able to deal with chunk-encoded
responses which don't, by their nature, have a content-length.

The service works when using a local file.
I did some more tests, and have identified the actual problem.
Its not in the PHP 5.3 release, rather its a "bug" in the Zend
AutoDiscover class provided by Zend.
I assume the reporter also might be using this to generate the WSDL's
?
I guess that in php 5.3 the soap server expects the content length to
be set in the header inorder to parse the complete wsdl, but the
AutoDiscover class does not send this.
By adding header('Content-Length: '.strlen($this->_wsdl->toXML())); to
the handle function in the AutoDiscover class things are working
I'll report the findings on the Zend bugtracker.

@sjoerd,
When I load the WSDL over HTTP there is no content-length header, as
the response is sent chunk-encoded. As stated in the original report, if
I save the WSDL to disk then it works, for example:-
<?php
$data = file_get_contents('http://myserver/path?wsdl');
file_put_contents("wsdl.xml", $data);
$serv = new SoapServer("wsdl.xml"); // works
?>
@stig,
The behaviour you describe with different size WSDL might backup the
theory that it's chunk-encoding related. With a small body size, I think
PHP *does* send a content-length header; but if the body is larger than
the output buffer (?) it will switch to chunk-encoding to allow for the
unknown, variable length.

Thank you for your bug report.
When you retrieve the WSDL over HTTP, does the Content-Length header
match the length of the WSDL? You can try saving the WSDL to disk and
load that one instead.

We have started porting our soap services from 5.2.x to 5.3 and see the
same problem here.
I have spend quite some time trying to identify the problem, and it
seemes to me that when the wsdl reaches a certain size it stops
working.
Ie. i have a service with 10 exposed methods. When all these methods
are exposed i get an error, same as Richards. If i cut down on the
number of exposed methods, to ie. 3 on the service it works.
This is services that is used in production on the 5.2.x builds, and
works perfectly there.
Looks to me that there might be a bug in the XML parsing of the WSDL
somewhere.

Description:
------------
SoapServer is failing on construction. I pass an URL with *valid* WSDL
xml, which is generated automatically.
- If I save the WSDL locally and load from disk it works.
- If I serve the WSDL remotely from a static .xml file it works.
- If I load the WSDL-url in my browser I get a well-formed XML
response.
- I can access the dodgy-wsdl URL via file_get_contents.
- Using 5.2.6 on another machine it works fine.
I inspected the http requests and think it could be related to chunked
encoding (it fails on the chunked encoding response).
Reproduce code:
---------------
<?php
$url = 'http://myserver/path?wsdl';
$serv = new SoapServer($url);
?>
I can probably provide a sample url privately.
Expected result:
----------------
$serv to be instantiated
Actual result:
--------------
SOAP-ERROR: Parsing WSDL: Couldn't load from
'http://myserver/path?wsdl' : Premature end of data in tag definitions
line 2
Below are the headers of the response that fails:-
Date: Tue, 11 Aug 2009 19:15:29 GMT
Server: Apache/2.2.8 (Unix) DAV/2 PHP/5.3.0
X-powered-by: PHP/5.3.0
Vary: Accept-Encoding,User-Agent
Connection: close
Transfer-encoding: chunked
Content-type: text/xml
