Request_Soap Class

The Request_Soap class is intended to process SOAP requests through PHP's SoapClient extension. Your PHP installation must be compiled with "--enable-soap". You can check the output of phpinfo() to see if this is the case.

Creating an instance

You can forge an instance of this class through the Request class: 

// create a Request_Soap object
$soap = Request::forge('http://soap.example.org/api/v1/this/info', 'soap');

// note that this only creates the object, it does not execute the request!

set_params($params)

The set_params method allows you to set parameters to pass on the SOAP request call.

Static No
Parameters
Param Default Description
$params required Array of parameters for the request.
Returns Request_Soap, for chaining
Example 
// create a Request_Soap object
$soap = Request::forge('http://soap.example.org/api/v1/this/info', 'soap');

// set some parameters
$soap->set_params(array('userid' => 12, 'data' => $payload));

set_option($option, $value)

The set_option method allows you to define a SoapClient option to be passed to the request.

Static No
Parameters
Param Default Description
$option required SoapClient option to set.
$value required Value to set this option to.
Returns Request_Soap, for chaining
Example 
// create a Request_Soap object
$soap = Request::forge('http://soap.example.org/api/v1/this/info', 'soap');

// set the username to be used in the request
$soap->set_option('login', $username);

set_options(array $options)

The set_options method allows you to define multiple SoapClient options to be passed to the request.

Static No
Parameters
Param Default Description

Example 
// create a Request_Soap object
$soap = Request::forge('http://soap.example.org/api/v1/this/info', 'soap');

// set a username and password to be used in the request
$soap->set_options(array(
	'login' => $username,
	'password' => $password,
	)
);

Returns Request_Soap, for chaining
Example

$soap = Request::forge('http://soap.example.org/api/v1/this/info', 'soap');

// add some parameters
$soap->add_param(array('userid' => 12, 'data' => $payload));

// or add a single one
$soap->add_param('data' => $payload);

Static No
Parameters
Param Default Description
$body required The data to be set as the response body.
