SoapClient::SoapClient

miguel dot angel dot fuentes dot casanova at gmail dot com (2013-06-28 07:39:38)

Somebody using SoapClient has sometimes a lot of CLOSE_WAIT states?
It's in a local connection in a openSuse 11 (x86_64, version 11, patchlevel 2) with Apache 2.2.22 and PHP 5.3.15.

Note that if libxml_disable_entity_loader() has been called, you cannot specify a WSDL file - you'll get an error that PHP "failed to load external entity".

To resolve this, add

<?php
libxml_disable_entity_loader(false);
?>

Above any calls to instantiate SoapClient.

Where you have the problem of 
"looks like we got no XML document SoapClient", really the real problem is the xml code from remote server is not clear (after last tag is possible that you have space or other caracter that the your supplier of service have lost :  no one is perfect!)
I've read some solution, like here, but you must to know that is possible, that is possible that the remote server don't wrong, and the "surplus" (latin word for added values) is needed.
In particolar with axis Java server, is possible that the configuration of server is needed and the "surplus" is one or more attachments...
The solution is 3:
1) contact your supplier if is possible to remove caracter if is an error (good luck! ;) )
2) use another class like nusoap resolve the problem (but has other problem!)
3) this technical solution:
when call the wsdl be sure that the option trace and exceptions are setted (the first true and the second false)

<?php
$SoapClient = new SoapClient(NULL, 
          array( 
....
            'trace'          => 1,
        'exceptions'      => 0
          )
?>
(if you don't do that you can't use the __getLastResponse)

Now You can do the request and use __getLastResponse() to obtain all the part..
<?php
$result  = $SoapClient -> problematicCall($par);
?>

After all  you obtain a variable like that:

-----=_Part_9325_126764118.1363377774664

  &lt;A&gt;PALADINUX&lt;/A&gt;
  &lt;ID&gt;12345&lt;/ID&gt;
  &lt;TIPODOC&gt;RC&lt;/TIPODOC&gt;
  &lt;RISPOSTA&gt;
&lt;/MESSAGGIO&gt;
</rxproblematicCallReturn></ns1:rxCatalogoMaterialiResponse></soapenv:Body></soapenv:Envelope>

Content-Type: application/zip
Content-Transfer-Encoding: binary
Content-Id: <43E91F7E7PALADINUXE07BF041A7BAC9>
-------------------------

Is easy understand if the added part is needed or not!
Now you can explode all the part and parse!

Hope this can help you.See ya in the cyberspace!

If your service is protected through basic http authentication and you're not using wsdl, you will have to put the login in the SoapClient's option:

<?php
$client = new SoapClient(
    null,
    array(
        'soap_version' => SOAP_1_2,
        'location' => ...
        ...,
        'login' => 'username',
        'password' => '*******',
    )
);
?>

chris at phblock dot atNoSpam (2011-11-04 05:57:45)

this is the syntax of typemap (found at http://svn.php.net/viewvc/php/php-src/trunk/ext/soap/tests/typemap012.phpt?view=markup)
<?php
$options=Array(
'typemap' => array(
array("type_ns"  => "http://schemas.nothing.com",
         "type_name" => "soap",
         "to_xml"  => "some_funktion_name")
));
?>

Chris Gunawardena (2011-08-15 00:56:24)

To monitor SOAP calls in and out of a unix server:
sudo tcpdump -nn -vv -A -s 0 -i eth0 dst or src host xxx.xxx.xxx.xxx and port 80
And always use 'cache_wsdl' => WSDL_CACHE_NONE

svenr at selfhtml dot org (2011-07-27 03:51:49)

The "classmap" option actually is a mapping from the "ComplexType" used within the SOAP to your PHP Classes.
Do not confuse the XML tag names returned for your request with these ComplexTypes. SOAP allows them to be different.
I had something like this:
...
<soapenv:body>
<ns1:TagName>
<ns1:Content>FooBar</ns1:Content>
</ns1:TagName>
</soapenv:body>
TagName is not the key you want to put in your classmap, you have to know the name of the ComplexType this TagName refers to. This info is contained inside the WSDL resource.

paulovitorbal at gmail dot com (2011-07-05 08:17:03)

When using certificates, in the parameter 'local_cert', use the file contents, not the name of the file.
example:
new soapclient("http://localhost/index.php?wsdl", array('local_cert'=>file_get_contents('./key.pem'),'passphrase'=>'password'));

willem dot stuursma at hyves dot nl (2011-05-30 04:56:32)

In PHP, you can have private properties defined in the classes you use in your classmap. So if you create a private property $foo in you class, and the SOAP element has a child element <foo />, the contents of $foo will be set to the contents of <foo />. This way you can control acces to the properties in your classes.
(Note: This does not work in Facebook's HPHP).

willem dot stuursma at hyves dot nl (2011-05-30 02:00:41)

If you want to use classes in a different namespace in your classmap, just use the backslash in the the target class name.

Example:
<?php
$classmap = array('result' => 'MyNamespace\\Result');
?>

You need to specify the backslash twice because it is the escape character in strings.

simonlang at gmx dot ch (2011-04-06 06:35:28)

Example for a soap client with HTTP authentication over a proxy:

<?php
new SoapClient(
    'service.wsdl',
    array(
        // Stuff for development.
        'trace' => 1,
        'exceptions' => true,
        'cache_wsdl' => WSDL_CACHE_NONE,
        'features' => SOAP_SINGLE_ELEMENT_ARRAYS,

        // Auth credentials for the SOAP request.
        'login' => 'username',
        'password' => 'password',

        // Proxy url.
        'proxy_host' => 'example.com', // Do not add the schema here (http or https). It won't work.
        'proxy_port' => 44300,

        // Auth credentials for the proxy.
        'proxy_login' => NULL,
        'proxy_password' => NULL,
    )
);
?>

Providing an URL to a WSDL file on the remote server (which as well is protected with HTTP authentication) didn't work. I downloaded the WSDL and stored it on the local server.

2. paramaters to soap functions must be passed as :

I'm experiencing the same problems when trying to load a WDSL fiel which is protected by basic http authentication, since the parameters login and password are just used for the request but not when reading the wdsl file. I just use the following workaround by downloading the xml file to a non-protected location on my server. Please notice that this doesn't support any kind of caching.

Hello folks!
A hint for developers:
When programming some soap server set the "soap.wsdl_cache_enabled" directive in php.ini file to 0:
soap.wsdl_cache_enabled=0
Otherwise it will give a bunch of strange errors saying that your wsdl is incorrect or is missing.
Doing that will save you from a lot of useless pain.

titan at phpdevshell dot org (2010-10-06 06:11:02)

It should be noted that if you receive a return error : 'Object reference not set to an instance of an object.'. This could be due to something as simple as passing the incorrect parameters. When you look at this XML:

    <Get xmlns="http://example.com">
      <request>
        <CustomerId>string</CustomerId>
        <From>dateTime</From>
        <To>dateTime</To>
      </request>
    </Get>

Your code should look something like this:

<?php
        try {
            $options = array(
                'soap_version'=>SOAP_1_2, 
                'exceptions'=>true,
                'trace'=>1,
                'cache_wsdl'=>WSDL_CACHE_NONE
            );
            $client = new SoapClient('http://example.com/doc.asmx?WSDL', $options);
// Note where 'Get' and 'request' tags are in the XML
            $results = $client->Get(array('request'=>array('CustomerId'=>'1234')));
        } catch (Exception $e) {
            echo "<h2>Exception Error!</h2>";
            echo $e->getMessage();
        }

$results = $client->Get(array('request'=>array('CustomerId'=>'842115')));
?>

If your WSDL file containts a parameter with a base64Binary type, you should not use base64_encode() when passing along your soap vars. When doing the request, the SOAP library automatically base64 encodes your data, so otherwise you'll be encoding it twice.

WSDL snipplet:
<element name="content" type="base64Binary" xmime:expectedContentTypes="*/*"/>

<?php
$string = 'data_you_want_to_send___like_xml_in_soap';
$soap_data = array(
        'foo' => 'bar',
      //'content' => base64_encode($string ) // don't do this
        'content' => $string //do this
);
$response = $client->Send($soap_data);
?>

Being new to SOAP, I was searching for a while to find out why my message was getting a response in soapUI, but not with my php code. The specific service I was addressing gives a HTTP 202 Accepted on success (no response), but returns a SOAP message on errors.
Situation:
Using an (authenticated) client connection, and a WDSL file, SOAP calls with type "One-Way" don't give a response header, even though a response is expected.
Solution:
When calling the client constructor, set SOAP_WAIT_ONE_WAY_CALLS in the $options['features'].

PHP 5.2.11 seems to not be very picky about the correctness of a WSDL.
Other SOAP clients were complaining about schema and namespace issues, while PHP's SoapClient worked completely fine. Fixing those issues for the other clients however broke PHP's SoapClient to the point where objects being passed to the SOAP method were becoming empty arrays on the server side.
Lesson learned: some elements were being prefixed with xsd: and others were not -- make absolutely sure your WSDL is correct and consistent (I'm using a tweaked WSDL_Gen.php).

james dot ellis at gmail dot com (2010-06-09 19:06:28)

I was having troubles getting responses from a Coldfusion SOAP server, with no obvious issues in the SoapClient used.
Eventually I found that the server was only accepting SOAP 1.1 requests and not 1.2. Not sure if this is a system wide Coldfusion setting but if you hit the same wall, try setting the SoapClient option "soap_version" to the constant SOAP_1_1 (which is the default but mine was defaulting to 1.2 as the client was being reused for another service)

ajcartmell at fonant dot com (2010-06-09 03:57:05)

There seems to be a problem with specifying empty strings for proxy_host and proxy_port options in recent versions of PHP (from a version later than 5.2.9, and equal to or earlier than 5.2.11).
Supplying empty string values for proxy_host and proxy_port causes "host not found" type errors: supplying NULL or FALSE works fine.

reinaldo at mandic dot com dot br (2010-05-25 07:43:44)

You need both certificates, privateKey and publicKey on the same file, on local_cert path to work.
# cat publicKey.pem privateKey.pem > key.pem

bhargav dot khatana at gmail dot com (2010-04-11 11:10:21)

It took me longer than a week to figure out how to implement WSSE (Web Service Security) headers in native PHP SOAP. There are no much resource available on this, so thought to add this here for community benefit.

Step1: Create two classes to create a structure for WSSE headers

<?php
class clsWSSEAuth {
          private $Username; 
          private $Password;  
        function __construct($username, $password) {
                 $this->Username=$username;
                 $this->Password=$password;
              }
}

class clsWSSEToken {
        private $UsernameToken;
        function __construct ($innerVal){
            $this->UsernameToken = $innerVal;
        }
}
?>

Step2: Create Soap Variables for UserName and Password

<?php
$username = 1111;
$password = 1111;

//Check with your provider which security name-space they are using.
$strWSSENS = "http://schemas.xmlsoap.org/ws/2002/07/secext";

$objSoapVarUser = new SoapVar($username, XSD_STRING, NULL, $strWSSENS, NULL, $strWSSENS);
$objSoapVarPass = new SoapVar($password, XSD_STRING, NULL, $strWSSENS, NULL, $strWSSENS);
?>

Step3: Create Object for Auth Class and pass in soap var

<?php
$objWSSEAuth = new clsWSSEAuth($objSoapVarUser, $objSoapVarPass);
?>

Step4: Create SoapVar out of object of Auth class

<?php
$objSoapVarWSSEAuth = new SoapVar($objWSSEAuth, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS);
?>

Step5: Create object for Token Class

<?php
$objWSSEToken = new clsWSSEToken($objSoapVarWSSEAuth);
?>

Step6: Create SoapVar out of object of Token class

<?php
$objSoapVarWSSEToken = new SoapVar($objWSSEToken, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS);
?>

Step7: Create SoapVar for 'Security' node

<?php
$objSoapVarHeaderVal=new SoapVar($objSoapVarWSSEToken, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'Security', $strWSSENS);
?>

Step8: Create header object out of security soapvar

<?php
$objSoapVarWSSEHeader = new SoapHeader($strWSSENS, 'Security', $objSoapVarHeaderVal,true, 'http://abce.com');

//Third parameter here makes 'mustUnderstand=1
//Forth parameter generates 'actor="http://abce.com"'
?>

Step9: Create object of Soap Client

<?php
$objClient = new SoapClient($WSDL, $arrOptions); 
?>

Step10: Set headers for soapclient object

<?php
$objClient->__setSoapHeaders(array($objSoapVarWSSEHeader));
?>

Step 11: Final call to method

<?php
$objResponse = $objClient->__soapCall($strMethod, $requestPayloadString);
?>

I found that WSDL fetching fails when using basic authentication in the soapclient. So I implemented the following workaround using wget. I realize wget may not be an option for some environments, in that case cURL would be the next simplest thing.

<?php
$wsdl = get_wsdl("https://example.com/soap/service?wsdl");
$this->client = new SoapClient($wsdl, array('user'=>'someuser', 'password'=>'somepassword'));

private function get_wsdl($url) {
    global $g;
    $url = escapeshellarg($url);
    $cache_file = "/tmp/soap.wsdl." . md5($url);
    
    //only fetch a new wsdl every hour
    if(!file_exists($cache_file) || filectime($cache_file) < time() - 3600) {
        $agent = escapeshellarg("--user-agent={$g['useragent']}");
        mwexec("wget --quiet --timeout=5 {$agent} --no-check-certificate --output-document={$cache_file} {$url}");
        if(!file_exists($cache_file)) {
            throw new Exception("Couldn't load WSDL at {$url}");
        }
    }
    return $cache_file;
}
?>

Though pointed out by jan at bestbytes, and discussed in bug #27777, one common source of the "Parsing WSDL: Couldn't find <definitions>" error is from trying to access a WSDL that is protected by HTTP authentication. Passing the login/password in the 2nd parameter doesn't always work; so if you encounter this error message and are trying to access a protected WSDL file, try passing the username and password in with the first parameter.

I had to struggle with a rather strange behavior when trying to consume standard Parlay X web services with no success. However, I found a remedy to my problem.

The problem which I faced was about an erroneous invalid HTTP basic authentication request sent to the web service. Although I was sending the right credentials, I was getting an authentication error. It turns out that PHP was sending HTTP requests to another endpoint which is not exposed directly through the web service and that end point does not require authentication. 

My remedy for that issue was by using this simple lines in the example of using sendSms Paraly-X method.

First, creating a soap client without any HTTP authentication options: 

<?php
$client = new SoapClient($wsdl_url);             
?>

The above request will cache the wsdl in the /tmp directory. Immediately after this construction we create another soap client, this time with HTTP authentication options:

<?php
try {                                            
        $client = new SoapClient($wsdl_url, array('login' => "griffin",
                                            'password'       => "password"));
} catch (Exception $e) {                           
        printf("Error:sendSms: %s\n",$e->__toString());
        return false;                              
} 
?>

Now it should work without any problem. Without the second call, PHP will call sendSms without credentials resulting in a failed attempt due to missing authentication information. I found this procedure to be the simplest.

This process should be done every time the cached wsdl expires, or simply a one can increase the time-to-live for the cached wsdl from php.ini

Note that creating a soap client for an invalid URL (you do test what happens, when a service is not available, right?) usually throws an exception which can be caught with try..catch. However, if xdebug is active you will get a fatal error, which obviously cannot be caught.

I had an issue figuring out the use of classmap that took me quite a while to figure out. I was assuming the WSDL type the docs were referring to was the name of the element being returned in the SOAP, so like,
<ns1:node id="8675309" />
and I was wondering why mapping
'classmap'=>array('node'=>'MyNode')
did nothing.
That's because in my WSDL I defined node as:
<xsd:element name="node" type="tns:nodeType" />
The classmap I needed was:
'classmap'=>array('nodeType'=>'MyNode')
I was able to find the type names using SoapClient->__getTypes()
Later, I realized where I could look inside the WSDL for the typename I needed.
I dunno if I missed something painfully obvious but maybe this can clear up some of the docs.

We've had some problems using SoapClient connecting to an external server via Microsoft ISA (presently v.2006 but this may apply to other versions too). We supply the proxy_host, proxy_port, proxy_login and proxy_password but the ISA server reports the login in its logs as "anonymous".
Our sysadmin believes this is because PHP is not supplying NTLN information (Windows security protocol) in the correct format (and whether it should work with proprietary proxies is of course another debate). We'd tried "username", "DOMAIN\username" to no effect. The solution is to add an exception in the ISA server for the target hostname/IP; null can then be supplied for proxy_login and proxy_password and the connection should then work as expected.
On a slightly related note, if you are having problems make sure the port number is supplied as an integer. Some versions of PHP will not use the proxy with SoapClient if the port number is supplied as a string.

jan at bestbytes dot de (2009-02-12 07:32:15)

You CAN get a wsdl, if basic authentication is required:

<?php 

$login = 'bert';
$password = 'berts password';

$client = new SoapClient(
    'http://' . urlencode($login) . ':' . urlencode($password) . '@www.server.com/path/to/wsdl',
    array(
        'login' => $login,
        'password' => $password
    )
);

?>

For anyone having trouble with ArrayOf_xsd_string and getting an error similar to 'No deserializer defined for array type {http://www.w3.org/2001/XMLSchema}string'
Try using the 'features' param, set to SOAP_USE_XSI_ARRAY_TYPE - this makes sure the correct deserializer is used.

eg, 
<?php
$client = new SoapClient("some.wsdl", array('features' => SOAP_USE_XSI_ARRAY_TYPE));
?>

i was looking for a good example and couldnt find one,
finally found it somewhere(forgot where) i think this is
the best example to make a soap request with multiple params

$params->AWSAccessKeyId = AMAZON_API_KEY;
$params->Request->SearchIndex = 'Books';
$params->Request->Keywords = 'php5 oop';
$amazon = new SoapClient('http://webservices.amazon.com
/AWSECommerceService/AWSECommerceService.wsdl');
$result = $amazon->itemSearch($params);

having xdebug may interfere with the constructor throwing exceptions

When using classmap option to map the SOAP results to a class, the constructor
of the object you've mapped to is not called.
$client = new SoapClient("url_to_wsdl",
array('classmap' => array('contact' => "Contact"));
$params = array("1");
$contact = $client->__soapCall("get_contact", $params);
Expected result:
A contact object that has properties initialized (i.e. db connections,
....).
Actual result:
A contact object without the properties.
Thanks for your help.

The same goes for using an SSL client certficate, the SoapClient will only present the certificate on the actual remote call, not when getting the WSDL. The workaround is the same as above. HttpRequest works as expected.

The "cache_wsdl" option takes constants like WSDL_CACHE_NONE or WSDL_CACHE_DISK that are listed on the "SOAP constants" page -> /manual/en/soap.constants.php

A note regarding boolean values that may seem obvious on reflection but could be a gotcha for some:

Seeing a SOAP request example with <SomeBooleanParam>true</SomeBooleanParam> may lead you to pass in string "true" or "false" as the parameter, which is incorrect - the correct method is to use boolean data types.

<?php
$client = new SoapClient($wsdl,$options);
$method = "DoSomething";
$params = new stdClass;

$params->SomeBooleanParam = TRUE;
$client->$method($params);
/**
 simplified request snippet would be
 <SomeBooleanParam>true</SomeBooleanParam>
**/

//this will also be correct, but not for the right reasons:
$params->SomeBooleanParam = "true";
$client->$method($params);
/**
 simplified request snippet would be
 <SomeBooleanParam>true</SomeBooleanParam>
**/

//this is where you may be wondering what is going on
$params->SomeBooleanParam = "false";
$client->$method($params);
/**
 simplified request snippet would be
 <SomeBooleanParam>true</SomeBooleanParam>
**/

//you need to do this instead
$params->SomeBooleanParam = FALSE;
$client->$method($params);
/**
 simplified request snippet would be
 <SomeBooleanParam>false</SomeBooleanParam>
**/
?>

Hope that helps!

If you want to use compression there is a missing parameter in the example above:

<?php
$client = new SoapClient("some.wsdl", 
  array('compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | 5));
?>

If you use SOAP_COMPRESSION_GZIP you have to add the compression level. Otherwise it will not compress the request. Took me some hours ;)

Oops!
I have written the wrong exception message in my last post.
The correct exception is:
SoapFault exception: [Client] looks like we got no XML document in <document>

giosh94mhz (2007-07-08 11:28:34)

If you get the following exception:

'Cannot open the XML file: the file is not well-formatted!'

PHP files of your SOAP-server contains syntax-error (probably).

If everything looks ok, try to remove EVERY blank-space and new-line outside the <?php ... ?> tag... this should save you an headache!

As noted in the bug report http://bugs.php.net/bug.php?id=36226, it is considered a feature that sequences with a single element do not come out as arrays. To override this "feature" you can do the following:
$x = new SoapClient($wsdl, array('features' =>
SOAP_SINGLE_ELEMENT_ARRAYS));

matt_schiros at academicsuperstore dot com (2006-11-30 12:26:40)

When using classmap to map the SOAP results to a class, the constructor of the object you've mapped to is _not_ called. This applies to the PHP5 __construct() and the PHP4 ClassName() constructors.

Marius Mathiesen (2006-03-01 04:57:51)

I kept having a problem using an HTTP proxy with SOAP. The proxy_port parameter has to be an integer, ie. "proxy_port"=>"80" won't work, you'll have to use "proxy_port"=>80.
HTH,
Marius

php at sowen dot de (2005-12-22 06:40:42)

If you're using CLI and there are multiple IP addresses available for outgoing SOAP-requests, try this "secret" to set outgoing IP:
e.g. for local IP 10.1.4.71:
$opts = array('socket' => array('bindto' => '10.1.4.71:0'));
$context = stream_context_create($opts);
$client = new SoapClient(null, array('location'=>'http://...','uri' => '...','stream_context' => $context));
You can also set other options for the stream context, please refer to this page:
Appendix M: http://www.php.net/manual/en/wrappers.php

jared at ws-db dot com (2005-08-28 14:31:11)

If you connect to a SoapServer, that has been created with session persistence, you can access the server's session id via SoapClient->_cookies[<session_id_name>][0]. This property becomes available after your first client method call.
I have only tested this with session.use_cookies=1.

Arjan van Bentem (2005-08-11 23:31:42)

When using HTTP basic authentication, PHP will only send the credentials when invoking the service, not when fetching the WSDL.
To solve this, one needs to fetch the WSDL manually (or using PHP, of course!) and store it on the file system. Obviously, the first parameter for SoapClient(..) then needs to refer to that local copy.
Alternatively, the user annotations at http://nl3.php.net/manual/en/ref.soap.php state that one could encode the login and password into the URL as well.
See http://bugs.php.net/bug.php?id=27777

Jim Plush (2005-07-11 12:56:04)

As of version 5.0.4 you can now dynamically change your location even if you're using a wsdl

<?php

$client = new SoapClient("http://some.host.net/wsdl/somefile.wsdl",array(
    "location" => 'myurl.com'));

?>

notice you can now use the "location" key. 
This means you can have the same wsdl file not define a location until runtime which is great if you have a development test site or if you distribute your files to other companies. 
Prior to this change you would have to ship a custom wsdl file to every client you had with their location hardcoded.

Brian Grayless (2005-03-04 14:30:43)

Using a WSDL file is the way to go, however, for my particular application, the LOCATION:PORT needed to be dynamic so that my SOAP clients would be able to call a different service based on the client domain.

If you are using a WSDL, SoapClient() requires a URL direct to an actual URL and does not let you use a PHP file that outputs the dynamic WSDL XML in its stead. So, I ended up making a separate WSDL for each possible service needed and had to maintain them all if the service description changed.

Finally, after some fiddling, I was able to create a PHP page with the proper Mime type headers so that I could then trick SoapClient() to think that it was being passed a file with a ".wsdl" extension.

Example:

<?php

// filename: wsdl.php

header('Content-Type: application/xml; charset=UTF-8');
header('Content-Disposition: attachment; filename="filename.wsdl"');

$wsdl = 'path/wsdl_name.wsdl';

// read in file
$handle = fopen($wsdl, "r");
$wsdl_xml = fread($handle, filesize($wsdl));
fclose($handle);

// put code here to replace url and port in xml

echo $wsdl_xml;

?>

Now, in order to make this work, you can't just call a relative path to the file. I believe it has to go through Apache to properly set the mime type headers, etc... So you would use a full "http://....." address as the path to the wsdl.php file.

<?php

//... somewhere in your soap client code

$wsdl_loc = "http://yourdomain.com/wsdl.php";

$soap_client = new SoapClient($wsdl_loc, $client_param_array);

?>

Another, perhaps not so clean, way of achieving this would be to modify your .htaccess file in the directory where your WSDL file exists to force ".wsdl" files to run through the PHP engine. Add the following to your .htaccess:

AddType application/x-httpd-php .php .wsdl

You can then put dynamic PHP code snippets in your *.wsdl files to change whatever values you need to.

There are pros and cons to each solutions. The Mime solution probably taxes the system more as it has to read the file in every time a soap request is made. The htaccess solution makes it so you have to depend on either a modified .htaccess or Apache conf file.

Perhaps if you set the "soap.wsdl_cache_enabled", using ini_set(), to 1 (default), the caching will make it so it doesn't read the file every time for the Mime solution.
