The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

PHP SOAP Uncaught exception - might depend on server settings?

Zones: SOAP, PHP Scripting Language, WebApplications

Tags: php, uncaught, soapfault, soap

Dear Experts,
I have a problem with a SOAP webservice written in PHP. The webservice is written by me and is used for a stock photography site to give the ability for external applications to upload images to the site.
The code worked perfectly on an old server, it works perfectly in the new dev environment but on production server with the exactly same piece of code I get the following error:
Fatal error: Uncaught SoapFault exception (...)
There shouldn't be any PHP-include errors, as if I call the PHP functions directly, they do the work well, but the same called from an external app or called through a PHP client run on the server this error is returned.
Might this happen because of different system setup or PHP settings? The php.ini, regarding SOAP related functions seem the same. Same PHP and Apache version as well. What other setting should be looked after?
Am chasing the problem in the right direction (server difference?) or this error is probably caused by something completely different?
If needed, I can post here some codes and the WSDL file as well.
Would appreciate any ideas that would come up to your mind, I'm getting pretty clueless. Thank you!

Can you show the code generating the exception?

It's going to be a trial and error issue to resolve.

Also, make sure you have the same version of all related dlls/extensions on the live server and of PHP itself.

Run this as info.php

<?php phpinfo(); ?>

on all the servers and check the differences.

Paying attention to SOAP settings.

Make sure the SOAP cache folder exists and you have permissions.

Output for Soap from php -i for me ...

soap

Soap Client => enabled
Soap Server => enabled

Directive => Local Value => Master Value
soap.wsdl_cache => 1 => 1
soap.wsdl_cache_dir => D:\Data\PHP\SOAP_Cache => D:\Data\PHP\SOAP_Cache
soap.wsdl_cache_enabled => 1 => 1
soap.wsdl_cache_limit => 5 => 5
soap.wsdl_cache_ttl => 86400 => 86400

Erm.

That's all I can think of for the time being.

Hmmm.

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

08.22.2007 at 03:28AM PDT, ID: 19744822

aburany:

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.

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

      return ws_login ($username, $password);
}

function 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();

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:

What OS and webserver are the servers?

I vaguely remember this being an issue.

Can you check the

always_populate_raw_post_data = On

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?
