Encoding

This package provides a pure PHP drop-in replacement for the ext-soap encoding logic. It can be used as a driver so that you don't have to install PHP's soap extension on your machine anymore.

Installation

composer require php-soap/encoding

Example usage

use Soap\Encoding\Driver;
use Soap\Encoding\EncoderRegistry;
use Soap\Engine\SimpleEngine;
use Soap\Psr18Transport\Psr18Transport;
use Soap\Wsdl\Loader\StreamWrapperLoader;
use Soap\WsdlReader\Locator\ServiceSelectionCriteria;
use Soap\WsdlReader\Model\Definitions\SoapVersion;
use Soap\WsdlReader\Wsdl1Reader;

// Loads the WSDL with the php-soap/wsdl-reader package:
$wsdl = (new Wsdl1Reader(new StreamWrapperLoader()))($wsdlLocation);

// Create an engine based on the encoding system that is provided by this package:
$engine = new SimpleEngine(
    Driver::createFromWsdl1(
        $wsdl,
        ServiceSelectionCriteria::defaults()
            ->withPreferredSoapVersion(SoapVersion::SOAP_12),
        EncoderRegistry::default(),
    ),
    Psr18Transport::createForClient($httpClient)
);

// Perform requests:
$decodedResult = $engine->request('Add', [
    [
        'a' => 1,
        'b' => 2
    ]
]);

/*
RESULT :

class stdClass#2135 (1) {
  public $AddResult =>
  int(3)
}
 */

EncoderRegistry

The EncoderRegistry is a collection of encoders that can be used to encode and decode data. By default, we provide a broad set of encoders to perform the basic soap encoding logic. However, you can configure how the encoding should be done by adding your own encoders to the registry.

Some examples:

use Soap\Encoding\ClassMap\ClassMap;
use Soap\Encoding\ClassMap\ClassMapCollection;
use Soap\Encoding\Encoder\SimpleType\DateTimeTypeEncoder;
use Soap\Encoding\EncoderRegistry;
use Soap\Xml\Xmlns;

EncoderRegistry::default()
    ->addClassMap('urn:namespace', 'TypeA', TypeA::class)
    ->addClassMap('urn:namespace', 'TypeB', TypeB::class)
    ->addClassMapCollection(new ClassMapCollection(
        new ClassMap('urn:namespace', 'TypeC', TypeC::class),
    ))
    ->addBackedEnum('urn:namespace', 'EnumA', EnumA::class)
    ->addSimpleTypeConverter(Xmlns::xsd()->value(), 'dateTime', new DateTimeTypeEncoder('Y-m-d\TH:i:s'))
    ->addComplexTypeConverter('urn:namespace', 'TypeC', MySpecificTypeCEncoder::class);

Encoder

Encoding and decoding is based on small XmlEncoder classes that are responsible for encoding and decoding a specific type of data. You can either use one of the provided encoders or create your own.

Building a custom encoder can look like this:

use Soap\Encoding\Encoder\Context;
use Soap\Encoding\Encoder\XmlEncoder;
use VeeWee\Reflecta\Iso\Iso;

/**
 * @implements XmlEncoder<MyClass, string> 
 */
class MySpecificTypeCEncoder implements XmlEncoder
{
    /**
     * @return Iso<MyClass, string>
     */
    public function iso(Context $context) : Iso
    {
        return new Iso(
            to: static fn (MyClass $value): string => $myClass->toXmlString(),
            from: static fn (string $value) => MyClass::fromXmlString($value),
        );
    }
}

Note: An encoder is considered to be isomorphic : When calling from and to on the Iso object, the data should be the same. More information about the concept can be found here.

For a full list of available encoders, you can check the Soap\Encoding\Encoder namespace. There are also some examples of common problems you can solve with these encoders in the examples/encoders directory.
