Zend\Soap\Client

The Zend\Soap\Client class simplifies SOAP client development for PHP programmers, and may be used in either WSDL or non-WSDL mode.

Under WSDL mode, Zend\Soap\Client uses a WSDL document to define transport layer options.

The WSDL description is usually provided by the web service the client will access. If the WSDL description is not made available, you may want to use Zend\Soap\Client in non-WSDL mode. Under this mode, all SOAP protocol options have to be set explicitly on the Zend\Soap\Client class.

Instantiation

The Zend\Soap\Client constructor takes two parameters:

Both of these parameters may be set later using the setWsdl($wsdl) and setOptions($options) methods respectively.

Non-WSDL mode requirements

If you use Zend\Soap\Client component in non-WSDL mode, you must set the 'location' and 'uri' options.

The following options are recognized:

The following demonstrate usage of compression options:

// Accept response compression
$client = new Zend\Soap\Client(
    'some.wsdl',
    ['compression' => SOAP_COMPRESSION_ACCEPT]
);

// Compress requests using gzip with compression level 5
$client = new Zend\Soap\Client(
    'some.wsdl',
    ['compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | 5]
);

// Compress requests using deflate compression
$client = new Zend\Soap\Client(
    "some.wsdl",
    ['compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_DEFLATE]
);

Performing SOAP Requests

After we've created a Zend\Soap\Client instance, we can perform SOAP requests.

Each web service method is mapped to a virtual Zend\Soap\Client instance method which takes parameters with common PHP types.

As an example, given the following server:

class MyClass
{
    /**
     * This method takes ...
     *
     * @param integer $inputParam
     * @return string
     */
    public function method1($inputParam)
    {
        /* ... */
    }

    /**
     * This method takes ...
     *
     * @param integer $inputParam1
     * @param string  $inputParam2
     * @return float
     */
    public function method2($inputParam1, $inputParam2)
    {
        /* ... */
    }

    /* ... */
}

$server = new Zend\Soap\Server(null, $options);
$server->setClass('MyClass');
$server->handle();

We can write a client as follows:

$client = new Zend\Soap\Client("MyService.wsdl");

// $result1 is a string
$result1 = $client->method1(10);

// $result2 is a float
$result2 = $client->method2(22, 'some string');
