PHP SOAP Interpreter

A PHP library for interpreting SOAP 1.1 and SOAP 1.2 messages. It can be used in WSDL or non-WSDL mode. The implementation is built on the top of PHP's SoapClient.

Requirement

PHP 5.4 --enablelibxml --enable-soap

Install

composer require meng-tian/php-soap-interpreter

Usage

An Interpreter instance is capable of generating SOAP request messages and translating SOAP response messages. Constructor of Interpreter class is the same as SoapClient. The first parameter is wsdl, the second parameter is an array of options.

It should be noted that not all options supported by SoapClient are supported by Interpreter. The responsibility of Interpreter is to interpreting SOAP messages, whereas the unsupported options are related to debugging or HTTP transportation. The supported options by Interpreter are: location, uri, style, use, soap_version, encoding, exceptions, classmap, typemap, cache_wsdl and feature. More detailed explanations of those options can be found in SoapClient::SoapClient.

Examples

Generate SOAP request message in WSDL mode

$interpreter = new Interpreter('http://www.webservicex.net/length.asmx?WSDL');
$request = $interpreter->request(
    'ChangeLengthUnit',
    [['LengthValue'=>'1', 'fromLengthUnit'=>'Inches', 'toLengthUnit'=>'Meters']]
);

print_r($request->getSoapMessage());

Output:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.webserviceX.NET/">
<SOAP-ENV:Body><ns1:ChangeLengthUnit><ns1:LengthValue>1</ns1:LengthValue><ns1:fromLengthUnit>Inches</ns1:fromLengthUnit><ns1:toLengthUnit>Meters</ns1:toLengthUnit></ns1:ChangeLengthUnit></SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Generate SOAP request message in non-WSDL mode

// In non-WSDL mode, location and uri must be provided as they are required by SoapClient.
$interpreter = new Interpreter(null, ['location'=>'http://www.webservicex.net/length.asmx', 'uri'=>'http://www.webserviceX.NET/']);
$request = $interpreter->request(
    'ChangeLengthUnit',
    [
        new SoapParam('1', 'ns1:LengthValue'),
        new SoapParam('Inches', 'ns1:fromLengthUnit'),
        new SoapParam('Meters', 'ns1:toLengthUnit')
    ],
    ['soapaction'=>'http://www.webserviceX.NET/ChangeLengthUnit']
);

print_r($request->getSoapMessage());

Output:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.webserviceX.NET/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body><ns1:ChangeLengthUnit><ns1:LengthValue xsi:type="xsd:string">1</ns1:LengthValue><ns1:fromLengthUnit xsi:type="xsd:string">Inches</ns1:fromLengthUnit><ns1:toLengthUnit xsi:type="xsd:string">Meters</ns1:toLengthUnit></ns1:ChangeLengthUnit></SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Translate SOAP response message

$interpreter = new Interpreter('http://www.webservicex.net/length.asmx?WSDL');
$response = <<<EOD
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <ChangeLengthUnitResponse xmlns="http://www.webserviceX.NET/">
            <ChangeLengthUnitResult>0.025400000000000002</ChangeLengthUnitResult>
        </ChangeLengthUnitResponse>
    </soap:Body>
</soap:Envelope>
EOD;
$response = $interpreter->response($response, 'ChangeLengthUnit');

print_r($response);

Output:

/*
Output:
stdClass Object
(
    [ChangeLengthUnitResult] => 0.0254
)
*/
