+# Encoder
+
+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
+
+```bash
+composer require php-soap/encoding
+```
+
+## Example usage
+
+```php
+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:
+
+```php
+use Soap\Encoding\EncoderRegistry;
+use Soap\Xml\Xmlns;
+
+EncoderRegistry::default()
+    ->addClassMap('urn:namespace', 'TypeA', TypeA::class)
+    ->addClassMap('urn:namespace', 'TypeB', TypeB::class)
+    ->addBackedEnum('urn:namespace', 'EnumA', EnumA::class)
+    ->addSimpleTypeConverter(Xmlns::xsd()->value(), 'dateTime', MyDateTimeEncoder::class)
+    ->addComplexTypeConverter('urn:namespace', 'TypeC', MySpecificTypeCEncoder::class);
+```
