i keep getting an stupid error in PHP related to SOAP which i can't solve. I've searched quite much via Google and in the official manual, but there is nothing helpful for me.
This is my problem: I got an official endpoint adress: $wsdl = example.com/wsdl, which i need to use for an soap request. The problem is that there is an proxy at my university trying to destroy all my work. So in general i need to get past my proxy, then access the wsdl file successfully and then authenticate at the web service.
What i have tried:
$wsdl = "example.com/wsdl";
$client = new SoapClient($wsdl,array('user' => 'username','password' => 'password'));
This throws the error:
"SOAP-ERROR: Parsing WSDL: Couldn't load from ... : failed to load external entity"
I also tried to cache the external wsdl file via file_get_contents by creating an valid stream with stream_context_create() which also resulted in the same error message.
How can i access this thing now? What am i doing wrong?

I am using Nusoap library in codeigniter. My code works fine in localhost as well as on server before i make new folder for my testing purpose. But now in testing folder it gives error like this.
I'm receiving this Error:
HTTP Error: Unsupported HTTP response status 404 Not Found
(soapclient->response has contents of the response)
I have searched solution Here and Here but it shows that endpoint is not set for client. On my side, when I print my object it has the endpoint value... What do I do wrong?
I can't connect the URL(http://carvilshoe.cz.cc/index.wsdl.php?wsdl) from my web browser too. I think you have to check your WebService status is online.
I have tried all the answers given in the following threads.
[1] Magento SOAP API - PHP Exception thrown for login method call: "looks like we got no XML document"
[2] Magento SOAP API - PHP Exception error “looks like we got no XML document”
I am able to load the WSDL in the browser and the WSDL URL is in this format
http://www.foo.com/api/v2_soap/?wsdl
This is the error am getting in the console:
looks like we got no XML document .
This error is usually related to Magento setting up a SoapServer, and not to your SoapClient call, which in turn means that it's usually a problem of your server not being able to fetch the WSDL. Connect toyour server via ssh and issue the following command (with your URL)
$ curl -i 'http://www.foo.com/api/v2_soap/?wsdl'
This will output the HTTP headers, and the response. My guess is the response isn't valid XML (includes debugging, or whitespace), curl couldn't connect to the server (because your host's networking is wrong) or your WSDL points to other WSDLs that can't be connected to.
Solve that problem, and you'll be good to go.
I am trying to connect to Amazon Web Services from my GAE account using a simple PHP script. However, the very first line is throwing an error:
$wsdlURI = 'http://www.webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl';
$soapClient = new SoapClient($wsdlURI);
I get this error:
SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://.....'failed to load external entity
When I do a simple file_get_contents on the above URL, it works just fine. Only the SoapClient is not able to get the handle on the wsdl file....and ONLY GAE seems to have this problem. I tried the same code on another server and everything works fine.
Is there any setting in GAE that I am missing??
This is also related to the disabling of loading of loading of external entities by default, you will need to enable this to get this to work.
First, you must create a php.ini file containing this line:
google_app_engine.enable_functions = "libxml_disable_entity_loader"
Then you add the following before your call.
libxml_disable_entity_loader(false);
For SoapClient to work using sockets application also needs to have billing enabled.
This issue is likely related: https://code.google.com/p/googleappengine/issues/detail?id=9858 .
Looks like SOAP needs sockets support, which is not yet part of the PHP runtime.
Check that you have the following extensions activated:
php open ssl
and
php soap client.
I am trying to get the content of WSDL from HTTPS Server
<?php
echo file_get_contents("https://zendsoap.lan/Zend_Soap_Server.php?wsdl");
?>
It Return:
Warning: file_get_contents() [function.file-get-contents]: SSL operation failed with code 1. OpenSSL Error messages: error:1408E0F4:SSL routines:func(142):reason(244) in /Applications/AMPPS/www/zendSoap.lan/Zend_Soap_Client.php on line 4

AND when I can goto the WSDL Location (https://zendsoap.lan/Zend_Soap_Server.php?wsdl): Everything looks fine.
P.S: Can anybody tell me how can I share the WSDL file
I agree with RockyFord regarding it being an SSL issue (I'm pretty sure you will have a self signed certificate in place and due to using SSL there are a few steps you will need to take in order to minimise security concerns). Regarding the immediate issue you could try fixing it with code similar to this:
$url = 'https://zendsoap.lan/Zend_Soap_Server.php?wsdl';
$contextOptions = array(
'ssl' => array(
'verify_peer' => true,
'CN_match' => 'zendsoap.lan' // assuming zendsoap.lan is the CN used in the certificate
)
);
$sslContext = stream_context_create($contextOptions);
$wsdlContent = file_get_contents($url, NULL, $sslContext);
(UPDATE: It might seem like an easy solution to change the code above to
'verify_peer' => false
while it may be ok for basic development it's not really a good idea and definitely shouldn't be used in a production environment as it introduces serious security concerns - see this excellent article on How to properly secure remote API calls over SSL from PHP code by Artur Ejsmont for more on this subject as well as the Transport Layer Security Cheat Sheet and Securing Web Services by OWASP)
To pick up on your point regarding sharing a WSDL from within a Zend Framework application you could do something like this to get started:
// go to application/configs/application.ini
// if your APPLICATION_ENV is development then add the following line in the development section:
phpSettings.soap.wsdl_cache_enabled = 0
The line above will prevent your wsdl being cached during development. Next you might want to create a SoapController and add this action like this:
public function serverAction()
{
$baseUrl = 'http://zendsoap.lan/soap/server';
if( isset( $_GET['wdsl'] ) ) {
$strategy = new Zend_Soap_Wsdl_Strategy_AnyType();
$server = new Zend_Soap_AutoDiscover($strategy);
$server->setUri($baseUrl);
$server->setClass('Application_Model_Web_Service');
$server->handle();
} else {
$server = new Zend_Soap_Server($baseUrl . '?wsdl');
$server->setClass('Application_Model_Web_Service');
$server->handle();
}
}
The nice thing about the approach above is the WSDL will be generated for you on the fly. You will have noticed the setClass() method is going to be called with 'Application_Model_Web_Service' passed as the only parameter. To test your configuration I recommend you create that class and insert the method below. Testing your configuration with a simple service containing a single method will help you with troubleshooting before you make the service more complex. Here is the example method:
// Note: you should definitely comment your methods correctly in the class so
// the WSDL will be generated correctly - by that I mean use #param and #return
// so the correct input and output types can be determined and added to the WSDL
// when the the ZF component generates it for you
/**
* #return string
*/
public function getMessage()
{
return 'ok';
}
(UPDATE: Also in response to the question you asked regarding using Zend_Soap_Client to access the web service, since it looks like you're intending to make it a secure service I'd suggest you raise a separate question regarding setting up secure soap services with php. If you explain more about what you're trying to do in that question you may get some good input from a range of experts on best practices :-)

I know you're new to SO so if you're happy with the answer you can accept it, also generally it's best to just reply to an answer rather than add another answer to reply. Easy when you know how of course and even easier when someone tells you ;-)
I tried your way of defining The Soap Server, only thing was I used my custom class instead of using Application_Model_Web_Service. I am using single files for Client & Server. When I run https://zendsoap.lan/Zend_Soap_Server.php without ?wsdl it result in this:
<SOAP-ENV:Envelope>
<SOAP-ENV:Body>
<SOAP-ENV:Fault>
<faultcode>WSDL</faultcode>
<faultstring>SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://zendsoap.lan/Zend_Soap_Server.php?wsdl' : failed to load external entity "https://zendsoap.lan/Zend_Soap_Server.php?wsdl"
</faultstring>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
And When I try file_get_contents() the way you told, I get this:
Warning: file_get_contents() [function.file-get-contents]: SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:func(144):reason(134) in /Applications/AMPPS/www/zendSoap.lan/https_soap_test.php on line 16
Warning: file_get_contents() [function.file-get-contents]: Failed to enable crypto in /Applications/AMPPS/www/zendSoap.lan/https_soap_test.php on line 16

Loads of thanks for your help.
Problem solved By changing 'verify_peer' => false
Can you (#dkcwd) please tell me what should be the code if I use Zend_Soap_Client without file_get_contents(). I mean is there any option which i can't find on internet to do something similar to 'verify_peer' => false.
Loads of Thanks to #dkcwd
UPDATE: Let me summarise what exactly I am doing, I am trying to create a basic SOAP Server over SSL. Before making Web Services available on my Production website, I have to test it on Development system with has got Self Signed Certificate (Whose authentication is a problem right now).
Following are the problems I am facing in that regard:
When I try to call https://zendsoap.lan/Zend_Soap_server.php?wsdl its works fine I can view the wsdl.
But when I try https://zendsoap.lan/Zend_Soap_server.php, I get this:
SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://zendsoap.lan/Zend_Soap_Server.php?wsdl' : failed to load external entity "https://zendsoap.lan/Zend_Soap_Server.php?wsdl"
Is that something I should be
The reason I made verify_peer=>false as I am running it on dev server so no need to verify my own created certificate, but obviously on production I want the Certificate to be verified.
This thing work fine with NuSoap but most of the stuff in NuSoap is deprecated for our server which is running PHP 5.4.6, So the most reliable solution for me using PHP's SOAP extension. And the reason for me using Zend is we're in process of moving our system from some third party framework to Zend Framework and everyday I get requests from client to add this & that new components, I assumed if I develop every new request from Client using Zend libraries then it will be easy for me in later stages to move to Zend Framework.
I hope I made some sense there.
Many Thanks in advance...
For the same WSDL, which is totally valid, I am able to access it properly using PEAR SOAP like this:
$WSDL = new SOAP_WSDL($this->wsdlUrl);
$proxy = $WSDL->getProxy();
But not able to make it work through Zend_Soap, when used like this:
$soapclient = new Zend_Soap_Client($this->wsdlUrl);
I get the following error when accessed through Zend_Soap_Client:
Error: SOAP-ERROR: Parsing WSDL: Couldn't load
from 'https://abc.xyz.com/agent/TestService.php?wsdl' : Start tag expected, '<' not found
Openssl is also enabled in my php.ini
Does anybody know why it doesn't work? and how I can fix it to use Zend_Soap properly?
You should check if the ssl-Certificate is valid. This Error Message is also thrown if ssl-certificate verification fails.
Check to make sure that no Ports are blocked in your hosting situation.
I've had the same error, though with different code just plain php, and was struggling with it for several days.
It turned out that my webhotel had blocked the port I needed to access the web service.
Or it could some proxy-related issue giving the same blocked result.
Are you using HTTP Authentication? Auth works with SOAP Client, however you cannot access password protected WSDL files
