The SerializerServiceProvider provides a service for serializing objects. This service provider uses the JMS\SerializerBundle for serializing.

Parameters

• serializer.src_directory: The directory where the JMS\SerializerBundle source is located.

• serializer.cache.directory: The directory to use for storing the metadata cache.

• serializer.naming_strategy.seperator (optional): The separator string used when normalizing properties.

• serializer.naming_strategy.lower_case (optional): Boolean flag indicating if the properties should be normalized as lower case strings.

• serializer.date_time_handler.format (optional): The format used to serialize and deserialize DateTime objects. Refer to the PHP documentation for supported Date/Time formats.

• serializer.date_time_handler.default_timezone (optional): The timezone to use when serializing and deserializing DateTime objects. Refer to the PHP documentation for a list of supported timezones.

• serializer.disable_external_entities (optional): Boolean flag indicating if the serializer should disable external entities for the XML serialization format.

Services

• serializer: An instance of JMS\SerializerBundle\Serializer\Serializer.

Registering

<?php

$app = new Silex\Application();

$app->register(new JMS\SerializerServiceProvider\SerializerServiceProvider(), array(
    'serializer.src_directory' => 'path/to/vendor/jms/serializer-bundle/src',
    'serializer.cache.directory' => 'path/to/cache'
));

Usage

Annotate the class you wish to serialize, refer to the annotation documentation

<?php

use JMS\SerializerBundle\Annotation;

// The serializer bundle doesn't need getters or setters
class Page
{
    /**
     * @Type("integer")
     */
    private $id;

    /**
     * @Type("string")
     */
    private $title;

    /**
     * @Type("string")
     */
    private $body;

    /**
     * @Type("DateTime")
     */
    private $created;

    /**
     * @Type("Author")
     */
    private $author;

    /**
     * @Type("boolean")
     */
    private $featured;
}

<?php
use JMS\SerializerBundle\Annotation;

// The serializer bundle doesn't need getters or setters
class Author
{
    /**
     * @Type("string")
     */
    private $name;
}

The SerializerServiceProvider provider provides a serializer service. Use it in your application to serialize and deserialize your objects:

<?php

use Silex\Application;
use JMS\SerializerServiceProvider\SerializerServiceProvider;
use Symfony\Component\HttpFoundation\Response;

$app = new Application();

// Make sure that the PHP script can write in the cache directory and that
// the directory exists.
$app->register(new SerializerServiceProvider(), array(
    'serializer.src_directory' => __DIR__."/../vendor/jms/serializer-bundle/src",
    'serializer.cache.directory' => __DIR__."/../cache/serializer"
));

// only accept content types supported by the serializer via the assert method.
$app->get("/pages/{id}.{_format}", function ($id) use ($app) {
    // assume a page_repository service exists that returns Page objects.
    $page = $app['page_repository']->find($id);
    $format = $app['request']->getFormat();

    if (!$page instanceof Page) {
        $this->abort("No page found for id: $id");
    }

    return new Response($app['serializer']->serialize($page, $format), 200, array(
        "Content-Type" => $app['request']->getMimeType($format)
    ));
})->assert("_format", "xml|json")
    ->assert("id", "\d+");
