SoapClient::__call

(PHP 5 >= 5.0.1, PHP 7)

SoapClient::__call — Calls a SOAP function (deprecated)

Description

public mixed SoapClient::__call ( string $function_name , string $arguments )

Calling this method directly is deprecated. Usually, SOAP functions can be called as methods of the SoapClient object; in situations where this is not possible or additional options are needed, use SoapClient::__soapCall().

If you are using a WSDL, the library will strip out anything from your parameters that is not defined in WSDL, without giving you any notice about this.

So if your parameters are not fully matching the WSDL, it will simply send no parameters at all.
This can be a bit hard to debug if you don't have access to the target server.

__soapCall() expects parameters in an array called 'parameters' as opposed to calling the function via it's WSDL name, where it accepts the parameters as a plain array.

I.e. if a function called sendOrder expects a parameter (array) called orderDetails, you can call it like this:

$orderDetails = array(/* your data */);
$soap->sendOrder(array('orderDetails' => $orderDetails));

Which is equivalent to:

$client->__soapCall('sendOrder', array('parameters' => array('orderDetails' => $orderDetails)));

Note the additional 'parameters' key used in __soapCall().

extend of __call thats adds a retry to handle the occasional 'Could not connect to host' exceptions

<?php
class LocalSoapClient extends SoapClient
{

  public function __call($function_name, $arguments)
  {
    $result = false;
    $max_retries = 5;
    $retry_count = 0;
    
    while(! $result && $retry_count < $max_retries)
    {
      try
      {
        $result = parent::__call($function_name, $arguments);
      }
      catch(SoapFault $fault)
      {
        if($fault->faultstring != 'Could not connect to host')
        {
          throw $fault;
        }
      }
      sleep(1);
      $retry_count ++;
    }
    if($retry_count == $max_retries)
    {
      throw new SoapFault('Could not connect to host after 5 attempts');
    }
    return $result;
  }
}
?>

Hi,
This is a good example, for the SOAP function "__call".
However it is deprecated.

<?php
$wsdl = "http://webservices.tekever.eu/ctt/?wsdl";
$int_zona = 5;
$int_peso = 1001;
$cliente = new SoapClient($wsdl);
print "<p>Envio Internacional: ";
$vem = $cliente->__call('CustoEMSInternacional',array($int_zona, $int_peso));
print $vem;
print "</p>";
?>

I'm writing PHP SOAP client (based on php_soap extension) which uses Google AdService, 
today, I tried to create sample Ad using   AdService::addAds()  and discovered that my SOAP library does not pass 
"headline", "description1", "description2"  parameters in SOAP request. 

First, I thought that this was something wrong with my data, coz I was getting validation errors like 
"One or more input elements failed validation."   Then I decided to take a look at WSDL description 
https://adwords.google.com/api/adwords/v11/AdService?wsdl

And voilà !  I've found this:

<complexType name="Ad" abstract="true">
<sequence>
  <element name="adGroupId" type="xsd:int"/>
  <element name="adType" nillable="true" minOccurs="0" type="impl:AdType"/>
  <element name="destinationUrl" nillable="true" minOccurs="0" type="xsd:string"/>
  <element name="disapproved" type="xsd:boolean"/>
  <element name="displayUrl" nillable="true" minOccurs="0" type="xsd:string"/>
  <element name="exemptionRequest" nillable="true" minOccurs="0" type="xsd:string"/>
  <element name="id" type="xsd:long"/>
  <element name="status" nillable="true" minOccurs="0" type="impl:AdStatus"/>
</sequence>

</complexType>

There is no any ''description", "headline1", "headline2", however there is another complexType 

<complexType name="TextAd">
    <complexContent>
    <extension base="impl:Ad">
    <sequence>

<element name="description1" nillable="true" type="xsd:string"/>
<element name="description2" nillable="true" type="xsd:string"/>
<element name="headline" nillable="true" type="xsd:string"/>
</sequence>

</extension>
</complexContent>
</complexType>

So, the thing is when you are working with php_soap be aware of complexType extensions which does not work in php_soap when you try to do things like:

<?php

$client = new
    SoapClient(
       "https://adwords.google.com/api/adwords/v11/AdService?wsdl",
        array(  'trace'      => true,
                'exceptions' => true,
             )
      
    );

$entropy     = substr(md5(rand(0, time())), 0, 10);
//create Ad test structure
$sample_ad =  array(
               "id" => 0,
               "adGroupId" => 0,
               "adType" => 'TextAd',
               "disapproved" => false,
               "destinationUrl" => 'http://test.com',
               "displayUrl" => 'www.Test.com',
               "status" => "Paused", //  Enabled / Disabled
               "descr_iption1" => 'D1_'.$entropy,
               "des_cription2" => 'D2_'.$entropy,
               "head_line" => 'H_'.$entropy
        );

$client->addAds(array('ads' => array($sample_ad) );
?>
