How PHP Works ?

PHP works through a multi-step lifecycle process when handling web requests. It includes: 1. Parsing, compilation, and scanning of PHP code when the web server starts. 2. When a request is made, PHP initializes extensions and populates variables through each extension's MINIT and RINIT methods. 3. PHP executes the requested page's code. 4. After page execution, PHP performs cleanup by calling each extension's RSHUTDOWN method and unseting variables. 5. PHP finally shuts down by calling each extension's MSHUTDOWN method to unregister handlers and free memory.

With PHP 5.6 there are some great new features. We'll go over some of these features and how to use them. This includes variadic functions, constant scalar expressions, exponentiation, splat operator, use const/function, php input, phpdbg, and more. We will also cover deprecated features in PHP 5.6. Want to get involved with upcoming release? I'll show you how you can 'make_test' to start helping out.

PHP, Under The Hood - DPC

Anthony Ferrara

PHP is one of the most popular open source programming languages in the world. It powers some of the highest traffic sites in the world, and at the same time it powers some of the lowest traffic sites in the world. But have you ever wondered how it works under the hood? Have you been overwelmed by the thought of looking at the C code that runs PHP? Well, this talk is for you! We're going to explore how PHP works under the hood, by looking at a PHP implementation of it: PHPPHP! Have you ever wondered what an OPCODE Cache is really doing? Have you ever wondered what a T_PAAMAYIM_NEKUDOTAYIM is? Have you ever wondered why an interpreted languages has a compiler? We'll explore all of these topics, and more! And the best part of it all? You don't need to know C to understand the details! Using PHPPHP, we can explore the language details in a high level language, where things like memory management don't get in the way of the real content. If you've ever wanted to know how PHP works, this is the talk for you!

Being functional in PHP (PHPDay Italy 2016)

David de Boer

Functional programming, though far from new, has gained much traction recently. Functional programming characteristics have started to appear in the PHP world, too. Microframeworks such as Silex and Slim, middleware architectures such as Stack and even standards such as PSR-7 rely on concepts such as lambdas, referential transparency and immutability, all of which come from functional programming. I’ll give you a crash course in Erlang, a pragmatic functional language to make you feel familiar with the functional paradigm. By comparing code samples between Erlang and PHP, you’ll find out how you can employ functional programming in your PHP applications where appropriate. You’ll see that functional programming is nothing to be scared of. On the contrary, understanding its concepts broadens your programming horizon and provides you with valuable solutions to your problems.

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Securing your Kubernetes cluster_ a step-by-step guide to success !

KatiaHIMEUR1

Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster. However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks. In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
