THE PHP 7 STORY by Zeev Suraski
Amphitéâtre Moebius 23/11/2015 11:00-11:45

PHP 7 is literally right around the corner, and in fact should already be out by the time this session takes place! With the previous major release of PHP having happened more than a decade ago, this is a very exciting milestone in PHP’s history that promises to bring both far-reaching performance boosts for real world workloads and a host of new features. In this session, Zeev will share the evolution of PHP’s major versions, the behind-the-scenes story of how PHP 7 came to be and its key benefits and features.

ONE EXTENSION, THREE ENGINES by Derick Rethans
Auditorium Lucienne et André Blin 23/11/2015 11:45-12:15

In this talk, I am explaining how we went from supporting a legacy driver for one language engine (PHP) to an architecture where multiple language engines are supported. This is the tale of the new MongoDB driver for PHP and HHVM. We started off with one massively complex (and legacy) driver. The goal was an easy to maintain extension. In our case that became a joint venture between core drivers (in C/C++), and a user-land supporting library in PHP. Because there are now other engines that run PHP, such as HHVM and PHP 7, the only real work that needs to be done for porting to a new engine is the basic core driver. This talk explains the choices, considerations and issues that we ran into while developing the driver to work with multiple engines; and our first steps supporting Facebook’s HHVM.

COLLABORATION UPSTREAM / DOWNSTREAM by Remi Collet
Salle de commission 23/11/2015 14:30-15:00

Comment fonctionne la collaboration entre les projects (upstream) et les distributions (downstream). – attente des distributions – bénéfice pour les projets – distribution des binaires (PHP, et les extensions PECL) – distribuer les bibliothèques PHP dans un monde dominé par composer a-t-il encore du sens – distribution en .phar, quand upstream fait le boulot de downstream – Koschei ou l’intégration continue de la pile PHP dans Fedora

INTEROPERABLE PHP by Anatol Belski
Salle de commission 23/11/2015 15:00-15:30

This topic applies actually to any project retaining to be available cross platform. The talk occupies itself with how the interoperability question is handled in PHP. The primary focus lays on the low level differences between Linux/Windows. The expected audience are people interested to keep their PHP projects cross platform aware. As well – people interested on several internals details going under the carpet. As well – low level minded people like PHP extension or SAPI developers. Besides the general internal details, the recent changes to PHP7 in areas 64-bit support and thread safety are going to be addressed.

ZOOM SUR LES OBJETS PHP by Julien PAULI
Amphitéâtre Moebius 23/11/2015 15:30-16:15

Ce sujet traite des détails techniques internes concernant les objets PHP. Que fait PHP lorsque je crée un objet ? Combien d’objets maximum puis-je créer ? Quelle mémoire PHP y alloue-t-il ? Quand est-ce que PHP libère la mémoire de mes objets ? Comment fonctionnent les classes et les traits ? Que dire des destructeurs d’objets ? Toutes ces questions trouveront réponse dans cette présentation ayant pour but de vous montrer ce qu’il se passe sous le capot lorsque vous manipulez vos frameworks préférés au jour le jour.

PHP 7 – WHAT CHANGED INTERNALLY? by Nikita Popov
Amphitéâtre Moebius 23/11/2015 16:45-17:30

One of the main selling points of PHP 7 is greatly improved performance, with many real-world applications now running twice as fast… But where do these improvements come from? At the core of PHP 7 lies an engine rewrite with focus on improving memory usage and performance. This talk provides an overview of the most significant changes, briefly covering everything from data structure changes, over enhancements in the executor, to the new compiler implementation.
