Convert XSD into PHP classes.

With goetas-webservices/xsd2php you can convert any XSD/WSDL definition into PHP classes.

XSD2PHP can also generate JMS Serializer compatible metadata that can be used to serialize/unserialize the object instances.


There is one recommended way to install xsd2php via Composer:

  • adding the dependency to your composer.json file:
  "require": {
  "require-dev": {


With this example we will convert OTA XSD definitions into PHP classes.

Suppose that you have all XSD files in /home/my/ota, first of all we need a configuration file (as example config.yml) that will keep all the namespace and directory mappings information.

# config.yml
# Linux Users: PHP Namespaces use back slash \ rather than a forward slash /
# So for destinations_php, the namespace would be TestNs\MyApp

    '': 'TestNs\MyApp'
    'TestNs\MyApp': soap/src
#    'TestNs\MyApp': soap\src  #  on Windows

    'TestNs\MyApp': soap/metadata
#    'TestNs\MyApp': soap\metadata  #  on Windows
#  Uncomment this section if you want to have also symfony/validator metadata to be generated from XSD    
#  destinations_validation:
#    'TestNs\MyApp': soap/validation
#    'TestNs\MyApp': soap\validation  #  on Windows
  aliases: # optional
      MyCustomXSDType:  'MyCustomMappedPHPType'
  naming_strategy: short # optional and default
  path_generator: psr4 # optional and default
#  known_locations: # optional
#    "": somefile.xsd
#  known_namespace_locations: # optional
#    "urn:veloconnect:catalog-1.1": xsd/catalog-1.1.xsd
# configs_jms:  #optional
#   xml_cdata: false # Disables CDATA

Here is an explanation on the meaning of each parameter:

  • xsd2php.namespaces (required) defines the mapping between XML namespaces and PHP namespaces. (in the example we have the XML namespace mapped to TestNs\MyApp)

  • xsd2php.destinations_php (required) specifies the directory where to save the PHP classes that belongs to TestNs\MyApp PHP namespace. (in this example TestNs\MyApp classes will be saved into soap/src directory.

  • xsd2php.destinations_jms (required) specifies the directory where to save JMS Serializer metadata files that belongs to TestNs\MyApp PHP namespace. (in this example TestNs\MyApp metadata will be saved into soap/metadata directory.

  • xsd2php.aliases (optional) specifies some mappings that are handled by custom JMS serializer handlers. Allows to specify to do not generate metadata for some XML types, and assign them directly a PHP class. For that PHP class is necessary to create a custom JMS serialize/deserialize handler.

  • xsd2php.naming_strategy (optional) specifies the naming strategy to use when converting XML names PHP classes.

  • xsd2php.path_generator (optional) specifies the strategy to use for path generation and file saving

  • xsd2php.known_locations (optional) override remote location with a local file.

  • xsd2php.known_namespace_locations (optional) Specify schema location by namespace. This can be used to read schemas which import namespaces but do not specify schemaLocation attributes.

  • xsd2php.configs_jms.xml_cdata (optional) Specify if CDATA should be used or not in serialization.

Generate PHP classes and JMS metadata info

vendor/bin/xsd2php convert config.yml /home/my/ota/OTA_Air*.xsd

This command will generate PHP classes and JMS metadata files for all the XSD files matching /home/my/ota/OTA_Air*.xsd and using the configuration available in config.yml

Serialize / Unserialize

XSD2PHP can also generate for you JMS Serializer metadata that you can use to serialize/unserialize the generated PHP class instances.

The parameter aliases in the configuration file, will instruct XSD2PHP to not generate any metadata information or PHP class for the {}MyCustomXSDType type. All reference to this type are replaced with the MyCustomMappedPHPType name.

You have to provide a custom serializer for this type/alis.

Here is an example on how to configure JMS serializer to handle custom types


use JMS\Serializer\SerializerBuilder;
use JMS\Serializer\Handler\HandlerRegistryInterface;

use GoetasWebservices\Xsd\XsdToPhpRuntime\Jms\Handler\BaseTypesHandler;
use GoetasWebservices\Xsd\XsdToPhpRuntime\Jms\Handler\XmlSchemaDateHandler;

$serializerBuilder = SerializerBuilder::create();
$serializerBuilder->addMetadataDir('metadata dir', 'TestNs');
$serializerBuilder->configureHandlers(function (HandlerRegistryInterface $handler) use ($serializerBuilder) {
    $handler->registerSubscribingHandler(new BaseTypesHandler()); // XMLSchema List handling
    $handler->registerSubscribingHandler(new XmlSchemaDateHandler()); // XMLSchema date handling

    // $handler->registerSubscribingHandler(new YourhandlerHere());

$serializer = $serializerBuilder->build();

// deserialize the XML into Demo\MyObject object
$object = $serializer->deserialize('<some xml/>', 'TestNs\MyObject', 'xml');

// some code ....

// serialize the Demo\MyObject back into XML
$newXml = $serializer->serialize($object, 'xml');

To disable the CDATA, configure JMS as so:

    xml_cdata: false



use Symfony\Component\Validator\Validation;

// get the validator
$builder = Validation::createValidatorBuilder();
foreach (glob('soap/validation/*.yml') as $file) {
$validator =  $builder->getValidator();

// validate $object
$violations = $validator->validate($object, null, ['xsd_rules']);

Dealing with xsd:anyType or xsd:anySimpleType

If your XSD contains xsd:anyType or xsd:anySimpleType types you have to specify a handler for this.

When you generate the JMS metadata you have to specify a custom handler:

# config.yml

      anyType: 'MyCustomAnyTypeHandler'
      anySimpleType: 'MyCustomAnySimpleTypeHandler'

Now you have to create a custom serialization handler:

use JMS\Serializer\XmlSerializationVisitor;
use JMS\Serializer\XmlDeserializationVisitor;

use JMS\Serializer\Handler\SubscribingHandlerInterface;
use JMS\Serializer\GraphNavigator;
use JMS\Serializer\VisitorInterface;
use JMS\Serializer\Context;

class MyHandler implements SubscribingHandlerInterface
    public static function getSubscribingMethods()
        return array(
                'direction' => GraphNavigator::DIRECTION_DESERIALIZATION,
                'format' => 'xml',
                'type' => 'MyCustomAnyTypeHandler',
                'method' => 'deserializeAnyType'
                'direction' => GraphNavigator::DIRECTION_SERIALIZATION,
                'format' => 'xml',
                'type' => 'MyCustomAnyTypeHandler',
                'method' => 'serializeAnyType'

    public function serializeAnyType(XmlSerializationVisitor $visitor, $data, array $type, Context $context)
        // serialize your object here

    public function deserializeAnyType(XmlDeserializationVisitor $visitor, $data, array $type)
        // deserialize your object here

Naming Strategy

There are two types of naming strategies: short and long. The default is short, this naming strategy can however generate naming conflicts.

The long naming strategy will suffix elements with Element and types with Type.

  • MyNamespace\User will become MyNamespace\UserElement
  • MyNamespace\UserType will become MyNamespace\UserTypeType

An XSD for instance with a type named User, a type named UserType, a root element named User and UserElement, will only work when using the long naming strategy.

  • If you don't have naming conflicts and you want to have short and descriptive class names, use the short option.
  • If you have naming conflicts use the long option.
  • If you want to be safe, use the long option.
