PHP SOAP Extension

I was following this article to learn myself to prepare and use web services in my PHP5. Article explains very clearly how to deal with all basics. Unfortunately client built using SoapClient class work fine until you are not trying to connect web service build using PHP5 Soap extension. I tried to connect many services written in different languages with no problems, but connecting my own service in PHP5 returns exception "Uncaught SoapFault exception: [Client] looks like we got no XML document".

First I thought, that my WSDL (working on other platforms) does not work for me in PHP5, but I tried to check it using few WSDL validators and I found it OK.

Could anyone have an idea, where could be a problem? I`ve spent hours by googling Internet but with no success ;(.

Thank you for any advice.

I’ve just spend half my evening trying to solve this problem, and your not gonna believe the solution…

Did you by any chance copy&paste the text from this website? I know I did.
Did you also copy two whitespaces along with the rest, now comfortably resting before your ‘<?php’? I sure did.
Do your errors disappear as soon as you strip these two leading whitespaces (along with any trailing whitespaces behind ‘?>’ if they happen to excist) from your code? Yep, you guessed right, they did here.

I guess there is a parser at work behind the curtains somewhere which is rather strict, perhaps a bit to strict.

(Tested with: WAMP5 1.6.6 : with PHP 5.2.0)

It seems an error found it’s way to the article (as far as I can tell from the W3C WSDL 1.1 examples[1]).
When simplifying the W3C example[2] the ‘tns’ was lost in the port binding in the service section:

On this page:

<service name=’StockQuoteService’>
<port name=’StockQuotePort’ binding=’StockQuoteBinding’>
<soap:address location=’http://[insert real path here]/server1.php’/>
</port>
</service>

Should be:

<service name=’StockQuoteService’>
<port name=’StockQuotePort’ binding=’tns:StockQuoteBinding’>
<soap:address location=’http://[insert real path here]/server1.php’/>
</port>
</service>

I noticed this when I tried to consume the webservice with Flash 8 (the PHP example above didnt have a problem with it).
I am not entirely sure if this is the fault of the author, or that Flash 8 is at fault. I *think* the parser is now looking for ‘StockQuoteBinding’ in the xmlns by default and not the xmlns:tns, yet I cant find where I’ve read about this behaviour, and the W3C specifications are not helping me either on this (or perhaps I am overlooking it there).

Either way, it’s perhaps usefull information to someone.

[1] http://www.w3.org/TR/wsdl#_services
[2] http://www.w3.org/TR/wsdl#_wsdl

When i copy code in this page to make webservice, i have error HTTP_ROW_POST_DATA.
It can find HTTP_ROW_POST_DATA.

Why???
Help me, help me to do.
Thanks

One of the deficiencies of the PHP5 SOAP extension is the inability to extract Headers sent from the clients. I think the only way to do this will be to manually extract and process any headers received from the clients by the server.

Another way to handle this, which is not exactly the right way to do it, would be to include the validation or authentication data in the message as part of the parameters to the function called instead of sending them as part of the header.

In the above example, 1 value is returned. Are 2 values returned as an array? Or how would that be done?

This is a great article.

But I am having a problem when it comes to crafting my own server/client with the example.

My server does not parse the WSDL file with error:

SOAP-ERROR: Parsing WSDL: Couldn’t load from

I have validated the file at:

http://www.mgateway.com/php/wsdlValidator/home.php

And it is valid, but the server response always has an error because it will not parse the wsdl.

Please help.

Thanks,
Chris

Hello,

about this:
$server = new Soapclient($wsdl [, $options]);

May you explian about all of options in this function?

I heard about keys,May you explain about them?

2-about example 2,May tell more about this:"The only argument against using it is that the client has to load the relevant WSDL document from the server before the RPC can be made"

3-Example 4:May you explain about this: Were you to do so, you should ensure that the return values are special objects of the SoapParam and SoapVar classes (as in the first example).

Soapvar? special object?

Thanks

you have mistake in xml definition. Check the definition line and look for example.org and replace it with your server and path.

I am having the same problem, and i am not behind a proxy…

Replacing example.org doesnt work !

I hope anyone can help us ?

good article.

for the above users’ errors. try to catch the exception…
i think this is where most peoples errors above are.

<?php
$client = new SoapClient("stockquote.wsdl",array(
"trace" => 1,
"exceptions" => 0));

try
{
$client->getQuote("ibm");
// or $client->__soapCall("getQuote", array("ibm"));
}
catch (SoapFault $exception)
{
echo ‘EXCEPTION=’.$exception;
}

?>

Get rid of the spaces before <?xml too…

This may be getting you, too:

Is it possible to send and receive an xml ‘envelope’ object such as the following?

<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope"&gt;
<env:Header>
<n:alertcontrol xmlns:n="http://example.org/alertcontrol"&gt;
<n:priority>1</n:priority>
<n:expires>2001-06-22T14:00:00-05:00</n:expires>
</n:alertcontrol>
</env:Header>
<env:Body>
<m:alert xmlns:m="http://example.org/alert"&gt;
<m:msg>Pick up Mary at school at 2pm</m:msg>
</m:alert>
</env:Body>
</env:Envelope>

If so, could you please provide an example using the php frame work?

Thanks,
Greg

I modified server1.php file as

<?php

class QuoteService {

private $quotes = array("ibm" => 198.42);

function getQuote($symbol) {

if (isset($this->quotes[$symbol])) {

return $this->quotes[$symbol];

} else {

throw new SoapFault("Server","Unknown Symbol ‘$symbol’.");

}

}

function getPrice($str) {

return "Take this price";

}

}

ini_set("soap.wsdl_cache_enabled","0");

//$data = file_get_contents(‘http://192.168.0.171/wsTest/client5.php’);

$server = new SoapServer("http://192.168.0.171/wsTest/stockquote.wsdl&quot ;

$server->setClass("QuoteService");

$server->handle();

?>

Client5.php reads like

<?php

$client = new SoapClient("http://192.168.0.171/wsTest/stockquote.wsdl&quot;,array(

"trace" => 1,

"exceptions" => 0));

try

{

$client->getQuote("ibm");

print "<pre>\n";

print "Request :\n".htmlspecialchars($client->__getLastRequest()) ."\n";

print "Response:\n".htmlspecialchars($client->__getLastResponse())."\n";

print "Headers:\n".htmlspecialchars($client->__getLastRequestHeaders())."\n";

print "</pre>";

echo $client->getPrice("hi");

}

catch (SoapFault $exception)

{

echo ‘EXCEPTION=’.$exception;

}

?>

I am not able to $client->getPrice(‘hi’);

Can you guys please guide me through the missing stuff or concept.
1. One more thing i would like to pass multiple arguments to the functions …I will highly appreciate any pointers towards solutions or root of errors.

abhikumar >
why do you use two services and two bindings?
you should use only one service and one binding to port type, which contain more operations

and btw replace the urn: with some as http://myserver/soap/stockoperations

Actually trying to follow this tutorial to get Soap going but it just keeps giving me the "HTTP 500 Error". On Windows Vista and PHP 5.2.5.Got "extension=soap_php.dll" indicated in php.ini .
I need some help. Thanks in advance.

The client script is:

<?php
$client = new SoapClient("http://localhost/c7/server1.php&quot ;
print($client->getQuote("ibm"));
?>

And the server1.php script is:

<?php
$quotes = array("ibm" => 98.42);

function getQuote($symbol) {
global $quotes;
return $quotes[$symbol];
}

$server = new SoapServer;
$server->addFunction("getQuote");
$server->handle();
?>

I have been trying to get this example to work. I have turned on ‘always_populate_raw_post_data’, however, I am getting the following error:

SoapFault exception: [SOAP-ENV:Server] Bad Request. Can’t find HTTP_RAW_POST_DATA

I am using PHP 5.2.2

sorry not speaking English … very good tutorial
i’m working on XP, localhost for testing

for Anonymous User (Mark) : very simple
copy :
php_soap.dll from your php-5.x.x-Win32/ext instal Php ZIP file
on :
local : like ( C:\php\extensions\php_soap.dll )

and verify php.ini on C:\windows ( search soap )

If you get the SOAp error "Error cannot find parameter", make sure the wsdl of your server and client are the same.

Espacially if you cnaged params of functions during development.

When developing both the client and server should have:
ini_set("soap.wsdl_cache_enabled", 0);

If you (like me) have this setting only at either server or client, you might get the above error and waste alot of time tracking it.

I always get above error when run the client. Anybody has an idea?
thanks. Looks like quite difficult to debug..

How can I biuld SOAP service over HTTPS using php. Please give me the example for server program,client program and WSDL. and how can I build SOAP Server WSDL without using "http://schemas.xmlsoap.org/soap/&quot;

I’m using external services, few of them can be unavaible, I’d like to use it as
try {
$client = new soapclient($wsdl);
}
catch(Exception $e)
{
…
}
or something else.

So, I except potential unavaiblity of service, but can’t do anything, I always get fatal error
Fatal error: SOAP-ERROR: Parsing WSDL: Couldn’t load from
and code is stopped.

Can I solve my problem and continue script if $wsdl is unavaible?

You only need to replace:
http://insert real path here]/server1.php
with real url to get working!

Thanks for the tip on adding tracing to SOAP calls in Zend. Very useful.

I have copied the code and wsdl. I have found and fixed all the errors as shown in the discussions. Including, changing the soap:address line to my localhost server. (PHP 5.2.8 with SOAP enabled)

My client always times out. I can see the wsdl loads from the client because I can see the functions, etc… But any call to the server times out after 30 seconds.

Is there any way to even see if the server is CALLING the soap server?

I’ve tried 3 other examples all with the same results. I presume it is something to do with my server, but I don’t know what it is and can’t find any help online.

Thanks for any help.

Got the provided example to work in a subdir just fine. http://myserver.xxx/soap01/client3.php,
but then if I made a change to the files to make a new methed, basically changing "getQuote" to "addQuote", it wont work in the subdir anymore.
It will work fine from the doc root, ie http://myserver.xxx/client3.php.

Some sort of path/name issue?
tired all combination I could think of with no luck.

Where you have
<port name=’StockQuotePort’ binding=’StockQuoteBinding’>

you should instead have
<port name=’StockQuotePort’ binding=’tns:StockQuoteBinding’>

Although php’s soap client will work with either, you will get invalid wsdl errors on many frameworks, and I think this may be causing some of the issues that people are having.

In case of this error remove the TWO white spaces from the server.php file you created ( at the beginning ).

Check all files ( client,server,wsdl for empty spaces in the beginning )
