PHP SOAP Uncaught exception - might depend on server settings?

Hmmm.

Do you use an auto_(ap|pre)pend_file on you dev servers? If so is this configured on the live server?

Thank you for your answers!

First of all, we don't use append/prepend files. Otherwise here is a list of differences between dev and production servers I found in PHP, can this indicate you something important maybe?

On production there's eAcc also installed:
with eAccelerator v0.9.5, Copyright (c) 2004-2006 eAccelerator, by eAccelerator

Keep Alive set to ON on dev, OFF on production
Max Requests            Keep Alive: off

extra modules here:
Loaded Modules   mod_info mod_rewrite mod_ssl

HTTP headers:
on dev: Connection       close
on prod: Keep-Alive       timeout=5, max=100
       Connection       Keep-Alive

session values (lifetime, gc_probabilty) are different, though I think those wouldn't make any change

SOAP settings are the same on both boxes, and are the following:
Soap Client       enabled
Soap Server       enabled

Directive      Local Value      Master Value
soap.wsdl_cache_dir      /tmp      /tmp
soap.wsdl_cache_enabled      1      1
soap.wsdl_cache_ttl      86400      86400

What's in the exception. Can you show the FULL error. It may have nothing to do with config.

For example, file permissions, or DB access or something like that.

If you've got a URL we can see the error if it is too complicated, then that would be useful.

Here is the URL where you can see the whole error message:

http://www.stockxpert.com/plugin/client_delete.php

Can you show the code for __doRequest(). I would like to see the entire XML being generated and any response you may get.

Sure, this is the client:

<?php
  $client = new SoapClient("sxc.wsdl");

  print_r($client->delete("plugintest","1234", "testphoto2.jpg"));
?>

and this is the server:

<?php

require_once ("common_ws.php");
      
function login($username, $password) {
      return ws_login ($username, $password);
}

function upload($username, $password, $title, $caption, $keywords, $filename) {
      return ws_upload ($username, $password, $title, $caption, $keywords, $filename);
}

function delete($username, $password, $files) {
      return ws_delete ($username, $password, $files);
}

ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache

$server = new SoapServer("sxc.wsdl");
$server->addFunction("login");
$server->addFunction("upload");
$server->addFunction("delete");
$server->handle();
?>

Drilling down ... ws_delete() please?

It is in common_ws.php, a usual PHP file containing these functions. If I call those functions separately, they run well, returning the array needed. Just if called as SOAP webservice from the client above it fails. Here is the code for ws_common: (pointed out ... the other two functions in order not to make this post here too long:

<?

require_once ("../common.phtml");
require_once ("../../common.php");
include "iptc_lib.php";

function ws_login ($username, $password) {
...
      }

      function ws_delete ($username, $password, $files) {
            $loginres = ws_login ($username, $password);
      
            if ($loginres['status_num'] != 0)
                  return ($loginres);

            briefcase_chkdir($username);
            $dir=briefcase_getdir($username);

            $files = explode (",",$files);
            if (!is_array ($files))
                  return (array ('status_num' => '10', 'status_msg' => 'No files provided.'));
            foreach ($files as $f) {
                  if (is_file ($dir ."/". $f)) {
                        $fname = $dir ."/" .$f;
                        if (!unlink ($fname))
                              $error = true;
            }
            else {
                        $error = true;
                  }
                  }
            if ($error) {
                  return (array ('status_num' => '10', 'status_msg' => 'Could not delete all files.'));
                  }
            else {
                  return (array ('status_num' => '0', 'status_msg' => 'Successfully removed all files.'));
            }
      }
      
function ws_upload ($username, $password, $title, $caption, $keywords, $filename) {
...
}

?>

Ah.

SoapClient->__call() - Calls a SOAP function (deprecated)

This method is deprecated. Use SoapClient->__soapCall() instead of it.


I can't tell you when it was deprecated.

Can you show the wdsl file also.

Hmm, but where was the call function in my code...?

wsdl  file.

Actually, sxc_wsdl.php is the server. (sorry for bit messed up naming)

http://stockxpert.com/plugin/sxc_wsdl.php

Outputs ...

<envelope SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><body><fault><faultcode>SOAP-ENV:Server</faultcode><faultstring>Bad Request. Can't find HTTP_RAW_POST_DATA</faultstring></fault></body></envelope>

What OS and webserver are the servers?

I vaguely remember this being an issue.

Can you check the

; Always populate the $HTTP_RAW_POST_DATA variable.
always_populate_raw_post_data = On

settings on both platforms.

; Always populate the $HTTP_RAW_POST_DATA variable.
always_populate_raw_post_data = On

it's commented out on both servers - have a ; before always_populate_raw_post_data = On

The servers are Ubuntu Linux, Apache2, PHP 5.1.2

Remove the ;

I am pretty sure that there is a way, even uncommented, that this field is NOT populated.

Checking source ...

From what I can tell, if you are sending the data via POST, then you use $_POST. If you are NOT using POST then you CAN use $HTTP_RAW_POST_DATA which seems wrong to me, but I may be reading that wrong.

Hmm.

soap.c is slightly different.

Can you check your php error log. There should be messages like ...

PHP-SOAP requires 'always_populate_raw_post_data' to be on please check your php.ini file

This will also generate the SOAP fault of ...

soap_server_fault("Server", "Bad Request. Can't find HTTP_RAW_POST_DATA" ...);

So. I think this is the issue.

Dear Sage,

sorry for the long delay - in the end there was a solution found to the problem. It wasn't exactly server setting related, but DNS related - due to some misconfiguration, the www.domain... from inside the server wasn't pointing back to the server, but to the load balancer in front of fronteds - this way, the server PHP couldn't be found from the WSDL file. After some configuring of DNS zone files the webservice worked perfectly.
I appreciate all your efforts to help with this, and would happily give you the points on this - however, I wouldn't accept one of your answers which wasn't exactly the solution. Could you advise me please how can I still add points?
