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
Warning: file_get_contents() [function.file-get-contents]: Failed to enable crypto 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

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...

I am having the weirdest, head splitting issue ever. The real issue is I'm getting a SOAP error SOAP-ERROR: Parsing WSDL: Couldn't load from 'some website' : failed to load external entity
In the past it was caused by the host not responding, bad URL, etc. But today I have no problem connecting to the host.
I'm using Symfony to run the API. I stripped ALL of the soap code from the API, created a simple test.php file and ran it from the command line on the exact server the API is running on, and it worked perfectly!
So I went back to the Symfony, flushed the cache. Still not working.
Next I decided to test the simplest methods I could and slapped 'file_get_contents('the url to the WSDL')` at the very top of the service that's making this SOAP call. It returns an empty string. No errors in the error log.
Next I tried moving that to the Controller. Still an empty string.
I tried file_get_contents('https://google.com'). Still, empty string no matter where in the Controller or Service I stick it. But, if on that same server I run a PHP script from the command line, it works no problem.
I don't even know where to begin showing you my code. Because it doesn't matter if file_get_contents() is in the controller, an entity, or the services it's using. Every time it returns an empty string.
As a side note, this is a development server. Which is an exact mirror of production (they just made an image of the production server). The whole API works fine in production and also on my local dev environment and in other environments it's been deployed to. So I'm entirely lost on why it's just this server, and just this particular application.
Any help is appreciated.

Update 1
As suggested by a friend I checked allow_url_fopen in both the cli php -i and apache phpinfo() and in both cases it's set to On
==
Update 2
As Pedro suggested I ran a cURL test in the controller of the API. And that worked, it retrieved the contents of the WDSL, and of course Google.
However, it doesn't solve my root problem with SOAP not retrieving the contents of a URL. Nor the obvious file_get_contents() not working. Does the PHP SOAP client use file_get_contents() to retrieve WSDLs?
==
Update 3
For those curious this is where the code is failing. I have to omit a lot of the class because it contains information specific to my company.
<?php
class Carrier implements CarrierInterface
{
//...omitted code
private function getSoapClient($wsdl)
{
// This line is what fails.
return new \SoapClient( $wsdl , array('trace' => true));
}
//...omitted code
public function quote(QuoteInterface $quote)
{
//Get the Soap Client
$client = $this->getSoapClient($this->quoteWSDL);
// The rest of the SOAP CALL
return $quote;
}
}
But in short, $this->quoteWSDL is just a URL, and yes it has a the correct value I've checked. But it fails when trying to construct the SOAP client stating SOAP-ERROR: Parsing WSDL: Couldn't load from '<url>' : failed to load external entity
==
Update 4 (with Kinda Solution)
Restarting apache fixed everything. I'm not sure why I didn't just ask the SysAdmin to do that sooner. That's like IT 101 right there. Thanks for your help. But now I'm curious why this was an issue to begin with. Weird.
My guess is that allow_url_fopen is disabled.
To enable it, you'll have to set allow_url_fopen=1 on php.ini.
Restart the Apache server to reload the configuration.
Have you considered using curl? Here's an example:
$url = "http://google.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$contents = curl_exec($ch);
curl_close($ch);
PS: For future users: Make sure you read the comments below.
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 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 looking for help with this problem and I hope someone give me that help. The error is the following:
Fatal error: SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://example.com/index.php/api/?wsdl' : failed to load external entity "http://example.com/index.php/api/?wsdl" in
/var/www/presentacion/app/code/local/Pengo/Extension/Model/Something.php on line 28
And the code that I'm using to connect to it is something like this:
$this->_soap = new SoapClient(http://example.com/index.php/api/?wsdl);
and there is where it says is the error.
I have been serching in Google, PHP forums, here in StackOverflow and Magento itself but I don't find the solution anywhere.
What I had seen is that the WSDL is never get parsed or loaded as the error says and none of its functions.
I tried connecting like this:
$options['location'] = http://example.com/index.php/api/?wsdl;
$options['uri'] = 'urn:Magento';
$this->_soap = new SoapClient(null, $options);
like this it doesn't dispatch any error like the others but there aren't functions to use, like in the other case it doesnt' load and parse the WSDL.
I am a bit frustrated because I have been developing this like 1 month and now that I am making some tests it shows this message, I had test it when it was really empty and new and it worked fine.
So any help would be appreciated.
Thank you.
Nine times out of ten this error is Magento is telling you it can't load the WSDL file. Magento is telling you this. It's not your local client code that's complaining.
Magento uses the PHP SoapServer object to create its SOAP API. The SoapServer object needs to access the WSDL as well. Try running the following from your server's command line
curl http://example.com/index.php/api/?wsdl
If I'm right, the above will timeout/fail.
Because of some quirks in DNS, it's surprisingly common that a server won't be able to access itself via its domain name. If this is the case, the quickest fix is adding an entry to the server's hosts file. (Talk to your server admin if none of that made sense)
Well after all the things that I test the only one that worked for me, I don't know why but it worked, was doing this in two separate machines. I tried that because I read that somewhere and I just do it and my Magento and Webservice now works perfectly. Whenever I try to do this local it dispatch the same error.
I hope this can help someone in the future and they don't have to knock their head on the wall because of this problem.
Thank you all for your answers and comments.
Alan Storm is right on the Money here!
Make sure that you check your server Hosts File, and that it includes an entry for both domain and www.domain. Espicialy important if you are doing server rewrites.
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
