SOAP Engine
===========

[](#soap-engine)

This package contains the contracts and models that allow you to create a customizable SOAP engine. The design looks like this:

[![Engine](docs/engine.png)](docs/engine.png)

- **Driver:** A driver is a combination of an encoder + decoder + metadata that can work together in order to process SOAP requests.
    - **Encoder:** Can encode mixed data into a valid SOAP Request.
    - **Decoder:** Can decode a SOAP Response into a mixed data result.
    - **Metadata:** Processes the WSDL and returns a collection of available types and methods.
- **Transport:** Sends the HTTP SOAP Request and receives the HTTP SOAP Response.

Every component above can be used seperately in order to create your own customized SOAP Engine.

Installation
============

[](#installation)

```
composer install php-soap/engine
```

Engines
-------

[](#engines)

This package provides engines that can be used in a generic way:

### SimpleEngine

[](#simpleengine)

The SimpleEngine is a wrapper around a previous defined `Driver` and a `Transport` implementation.

```
use Soap\Engine\SimpleEngine;

$engine = new SimpleEngine($driver,$transport);
```

### LazyEngine

[](#lazyengine)

You don't want to be loading WSDL files or SOAP services if you don't need to. By wrapping an engine in a lazy engine, you can prevent any WSDL loading from happening before actually requesting a resource.

```
use Soap\Engine\SimpleEngine;
use Soap\Engine\LazyEngine;

$engine = new LazyEngine(fn () => new SimpleEngine($driver, $transport));
```

Drivers
-------

[](#drivers)

This package provides drivers that can be used in a generic way:

### SimpleDriver

[](#simpledriver)

The SimpleEngine is a wrapper around a previous defined `Encoder`, `Decoder` and a `Metadata` implementation.

```
use Soap\Engine\SimpleDriver;

$engine = new SimpleDriver($encoder, $decoder, $metadata);
```

### PartialDriver

[](#partialdriver)

The PartialDriver is a wrapper around a previous defined `Encoder`, `Decoder` and a `Metadata` implementation. It is possible to only provide one of the required items. When some of the implementations are missing, it will throw a `DriverException` when the driver's method is invoked.

```
use Soap\Engine\PartialDriver;

$engine = new PartialDriver(metadata: $metadata);
```

List of available components:
-----------------------------

[](#list-of-available-components)

- [ext-soap-engine](https://github.com/php-soap/ext-soap-engine): An engine based on PHP's ext-soap.

    - **ExtSoapEncoder:** Uses PHP's `SoapClient` in order to encode a mixed request body into a SOAP request.
    - **ExtSoapDecoder:** Uses PHP's `SoapClient` in order to decode a SOAP Response into mixed data.
    - **ExtSoapMetadata:** Parses the methods and types from PHP's `SoapClient` into something more usable.
    - **ExtSoapDriver:** Combines the ext-soap encoder, decoder and metadata tools into a usable `ext-soap` preset.
    - **ExtSoapClientTransport:** Uses PHP's `SoapClient` to handle SOAP requests.
    - **ExtSoapServerTransport:** Uses PHP's `SoapServer` to handle SOAP requests.
    - **TraceableTransport:** Can be used to decorate another transport and keeps track of the last request and response.
- [psr18-transport](https://github.com/php-soap/psr18-transport/): Leverages your PSR-18 HTTP client to deal with the HTTP Layer.

    - **Psr18Transport**: Uses a PSR-18 HTTP client to handle SOAP requests. You can also use fiber-based Async clients!
    - Provides middleware to deal with some common SOAP quirks.
- [wsdl-reader](https://github.com/php-soap/wsdl-reader/): Provides an XML based PHP implementation for collecting WSDL meta-data.

    - **Wsdl1MetadataProvider**: Provides the methods and types from any WSDL 1 document.

Creating your own engine
------------------------

[](#creating-your-own-engine)

Every component of the engine has its own interface. You can choose to build an entire engine or a specific component. The interfaces look like this:

- [Decoder](src/Decoder.php)
- [Driver](src/Driver.php)
- [Encoder](src/Encoder.php)
- [Engine](src/Engine.php)
- [Transport](src/Transport.php)

### Testing your engine

[](#testing-your-engine)

To make sure that all components have the same end-result, we provide [a set of integration tests](https://github.com/php-soap/engine-integration-tests) that can be used to test your custom components.

Usage:

```
composer require --dev php-soap/engine-integration-tests

```

This will make following test cases available:

- [AbstractDecoderTest](https://github.com/php-soap/engine-integration-tests/tree/main/src/AbstractDecoderTest.php): Can be used to test a custom `Decoder`.
- [AbstractEncoderTest](https://github.com/php-soap/engine-integration-tests/tree/main/src/AbstractEncoderTest.php): Can be used to test a custom `Encoder`.
- [AbstractEngineTest](https://github.com/php-soap/engine-integration-tests/tree/main/src/AbstractEngineTest.php): : Can be used to test a custom `Engine` or `Transport`.
- [AbstractMetadataProviderTest](https://github.com/php-soap/engine-integration-tests/tree/main/src/AbstractMetadataProviderTest.php): : Can be used to test a custom `Metadata` or `MetadataProvider`.
