PHP Internals Deep Dive
English session - Advanced
In this talk we are going to dive deep into PHP's inner workings.
We will start by looking at how the language parser and scanner work, which convert scripts into an Abstract Syntax Tree. When then look at how PHP internal byte code is generated from this AST, and how the engine runs byte code.
Time Zones and Calendars are a PITA
English session - Advanced
In this presentation we will look at how to deal with time zones. This will particularly be relevant due to the changes in Canada with Daylight Saving Time.
We will see how it is hard to make assumptions on how they work, and explain how they came into existence. We'll focus mostly on how to handle them from within PHP, as well as how we (should) store them in databases. We'll also have a quick look at date manipulation when querying data.
