How to Make SOAP Calls Using PHP's SoapClient Class?

Creating SOAP Calls with PHP's SoapClient Class

When working with SOAP services as a client, structuring the proper SOAP call can be challenging. Using PHP's SoapClient class to make such calls can be daunting, especially for those less familiar with object-oriented coding.

Let's take the example of a SOAP function called "FirstFunction" that expects a "Contact" object as one of its parameters. The Contact object possesses the properties "id" and "name." Additionally, it requires a description and an amount.

Creating the SoapClient Object

Begin by referencing the WSDL file to establish a SoapClient object:

$client = new SoapClient("http://example.com/webservices?wsdl");

Structuring the Parameters

To create the "Contact" object, utilize the following code:

$contact = new Contact(100, "John");

Next, define the remaining parameters:

$description = "Barrel of Oil";
$amount = 500;

Combine these parameters into an array:

$params = array(
  "Contact" => $contact,
  "description" => $description,
  "amount" => $amount
);

Invoking the SOAP Call

Finally, invoke the SOAP call using the SoapClient's __soapCall method:

$response = $client->__soapCall("FirstFunction", array($params));

This complete code should successfully execute the desired SOAP call:

id = $id;
        $this->name = $name;
    }
}

$client = new SoapClient("http://example.com/webservices?wsdl");

$contact = new Contact(100, "John");
$description = "Barrel of Oil";
$amount = 500;

$params = array(
  "Contact" => $contact,
  "description" => $description,
  "amount" => $amount
);

$response = $client->__soapCall("FirstFunction", array($params));

var_dump($response);
