sfPot à Lille sur Docker et le web sémantique avec Symfony

Alexandre Salomé (SensioLabs) et moi (Les-Tilleuls.coop) animeront un nouvel apéro Symfony à Lille le 15 janvier.

Au programmes deux talks :

  • L’un sur le web de données avec Symfony ou seront évoqués les APIs REST, l’hypermedia, Schema.org, PHP Schema et HydraBundle.
  • L’autre sur Docker ou l’on parlera… de Docker !

Tout cela arrosé de bières belges.

Rendez-vous le 15 janvier à 19h au Bar Braz rue Doudain à Lille.

Generate a Symfony password hash from the command line

There is an easy way to generate a Symfony compliant password hash from the command line. Assuming you’re using the bcrypt algorithm (the preferred choice according to Symfony’s security best practices), the default cost (13) and you have PHP >= 5.5 installed, just run the following command:

 It will output something like:  $2y$13$7mBTrD0lgdgBxt1.YbdvOOeSOrPUYOBfeC1Ra2osPs9lpCHdplw1m

You can directly use this value in your app/config/security.yml  file:

Thanks to Sarah Khalil, a built-in Symfony command will be available in a next release (and that command will support all installed algorithms).

CoopTilleulsOVHBundle: OVH SDK integration in Symfony

I’ve just released a new tiny open source bundle under the Les-Tilleuls.coop umbrella: CoopTilleulsOvhBundle.

That bundle integrates the official PHP SDK provided by OVH and exposes it as a Symfony service. It also provides a convenient way to store API credentials in parameters.yml.

The OVH API provides a lot of features including dynamic server management (elasticity) and monitoring, SMS sending, telephony configuration, billing… Almost all services provided by the first european internet hosting company (from Roubaix, France – our neighbors!) are exposed through their API, and can now be used from any Symfony application.

As usual, the source code and tests are freely available on our GitHub account. The bundle can be installed using Composer.

“Persistence in PHP with Doctrine ORM” eBook for $5 until January 6th 2015

Persistence in PHP with the Doctrine ORM

 

Thanks to Packt’s eBook Bonanza, my book “Persistence in PHP with Doctrine ORM” is available for only $5 until January 6th. Enjoy it!

What you will learn from this book

  • Install Doctrine through the Composer dependency manager
  • Configure Doctrine Command Line Tools
  • Learn to manage relations between entities with different association types
  • Create data fixtures, a custom entity repository, and native SQL queries
  • Master the query builder to generate DQL queries
  • Get started with inheritance and lifecycle events

In Detail

Doctrine 2 has become the most popular modern persistence system for PHP. It can either be used as a standalone system or can be distributed with Symfony 2, and it also integrates very well with popular frameworks. It allows you to easily retrieve PHP object graphs, provides a powerful object-oriented query language called DQL, a database schema generator tool, and supports database migration. It is efficient, abstracts popular DBMS, and supports PHP 5.3 features.

Doctrine is a must-have for modern PHP applications.

Persistence in PHP with the Doctrine ORM is a practical, hands-on guide that describes the full creation process of a web application powered by Doctrine. Core features of the ORM are explained in depth and illustrated by useful, explicit, and reusable code samples.

Persistence in PHP with the Doctrine ORM explains everything you need to know to get started with Doctrine in a clear and detailed manner.

From installing the ORM through Composer to mastering advanced features such as native queries, this book is a full overview of the power of Doctrine. You will also learn a bunch of mapping annotations, create associations, and generate database schemas from PHP classes. You will also see how to write data fixtures, create custom entity repositories, and issue advanced DQL queries. Finally it will teach you to play with inheritance, write native queries, and use built-in lifecycle events. If you want to use a powerful persistence system for your PHP application, Persistence in PHP with the Doctrine ORM is the book you.

Approach

Persistence in PHP with the Doctrine ORM is a concise, fast, and focused guide to build a blog engine with advanced features such as native queries and lifecycle callbacks.

Who this book is for

This book is primarily intended for PHP developers and architects who want to increase their skills in the field of Persistence and ORM to map the data they are working on to objects they are using in programming. Basic knowledge of databases and PDO and working knowledge of PHP namespaces is a prerequisite.

 

Two free chapters are available on the Pack website.

PHP Schema: generate a fully functional PHP / Doctrine / Symfony data model from Schema.org vocabulary in minutes

PHP Schema is a code generator that instantly generates a PHP data model from the Schema.org vocabulary : browse Schema.org, choose the types and properties you need, run our code generator and you’re done! You get a fully featured PHP data model including:

  • A set of PHP entities with properties, constants (enum values), getters, setters, adders and removers. The class hierarchy provided by Schema.org will be translated to a PHP class hierarchy with parents as abstract classes. The generated code complies with PSR coding standards.
  • Full high-quality PHPDoc for classes, properties, constants and methods extracted from Schema.org.
  • Doctrine ORM annotation mapping including database columns with type guessing, relations with cardinality guessing, class inheritance (through the @AbstractSuperclass annotation).
  • Data validation through Symfony Validator annotations including data type validation, enum support (choices) and check for required properties.
  • Interfaces and Doctrine ResolveTargetEntityListener support.
    Custom PHP namespace support.
  • List of values provided by Schema.org with PHP Enum classes.

Bonus:

  • The code generator is fully configurable and extensible: all features can be deactivated (e.g.: the Doctrine mapping generator) and custom generator can be added (e.g.: a Doctrine ODM mapping generator).
  • The generated code can be used as is in a Symfony app (but it will work too in a raw PHP project or any other framework including Laravel and Zend Framework).

Why use Schema.org data to generate a PHP model?

Don’t Reinvent The Wheel

Data models provided by Schema.org are popular and have been proved efficient. They cover a broad spectrum of topics including creative work, e-commerce, event, medicine, social networking, people, postal address, organization, place or review. Schema.org has its root in a ton of preexisting well designed vocabularies and is successfully used by more and more website and applications.

Pick up schemas applicable to your application, generate your PHP model, then customize and specialize it to fit your needs.

Improve SEO and user experience

Adding Schema.org markup to websites and apps increase their ranking in search engines results and enable awesome features such as Google Rich Snippets and Gmail markup.

Mapping your app data model to Schema.org structures can be a tedious task. Using the generator, your data model will be a derived from Schema.org. Adding microdata markup to your templates or serializing your data as JSON-LD will not require specific mapping nor adaptation. It’s a matter of minutes.

Be ready for the future

Schema.org improves the interoperability of your applications. Used with hypermedia technologies such as Hydra it’s a big step towards the semantic and machine readable web. It opens the way to generic web API clients able to extract and process data from any website or app using such technologies.
