Guys, I'm stuck, banging my head off the desk for the past few hours.
I am trying to consume a service, and I have 8 other functions that I call that are almost IDENTICAL in nature to this one, but this one, results in a 'SOAP-ERROR: Encoding: Violation of encoding rules' error.
Heres the function call (wsdl omitted for security):
function CanLoadProduct($data){
$client = new SoapClient('wsdl-url');
$params = array('username' => $this->username,
'password' => $this->password,
'prod' => $data['productid'],
'mdn' => $data['mdn']);
try {
$reply = $client->__soapCall("CanLoadProduct", $params);
} catch (Exception $e) {
echo 'Error: ', $e->getMessage(), "\n";
print_r($params);
die();
}
if( $reply['result'] == 1 ){
return TRUE; // 1 = true
} else {
return FALSE;
}
}
Ok so this function, connects to a webservice, the required elements are: username, password, prod, mdn, all 4 of which I supply as part of the $params array. Username/Pass are defined earlier, and do work fine, as the other 8 functions consume the web service without any problems.
The $data[] array (that I pass to the function), contains: $data['productid'] $data['mdn'] nothing else is used.
I am getting
SOAP-ERROR: Encoding: Violation of encoding rules
for some unexplained reason, and Googling this error gets me nowhere. Anyone else run into this? Running PHP 5.2.9-2. The strange thing is this is identical to this function which works 100%:
function GetPIN($productid){
$client = new SoapClient('wsdl-url');
$params = array('username' => $this->username,
'password' => $this->password,
'prod' => $productid);
try {
$reply = $client->__soapCall("GetPIN", $params);
} catch (Exception $e) {
echo 'Error: ', $e->getMessage(), "\n";
die();
}
return $reply;
}
Here is the WSDL (should have posted this first):

If you upgrade your PHP version to 7.3 or later, the previous WSDL cache may stop working.
The default install directory is /tmp
and disabling cache or deleting the wsdl* cache files should remove the problem. I would recommend clearing the cache, or else your server will pull the WSDL every time (which may not be desirable).
I had the same problem.
In soapUI preferences I checked the option Preferences → Editor Settings → Validate Responses and I received this information:
line 3027: Invalid decimal value: unexpected char '44'.
This solved my problem. Field contained wrong type value.
It looks like you have a type mismatch somewhere, either while assembling your request (one of the parameters is not of type string), or the server returns something other than an int (violating the WSDL response definition and thus causing the client to consider the response invalid, as it expects something else).
Some additional observations/questions:
$client->__soapCall("CanLoadProduct", $params)
instead of $client->CanLoadProduct($username, $password, etc.)
? (The first version is a lower level variation which is intended to be used for non_WSDL scenarios. The second version might give you a more detailed error/exception)I had the same problem when trying to pass XML as a parameter to one of my webservices. Wrapping the XML data in <![CDATA[ ... ]]>
got rid of the SOAP-ERROR: Encoding: Violation of encoding rules and everything worked fine.
Other details:
1. The parameter was defined as xsd:string as well.
2. WSDL was document/literal.
3. Using built in SOAP class with php 5.2.10.
