The document discusses the abstract syntax tree (AST) representation of PHP code. It describes how the PHP lexer and parser work together to convert PHP source code into an AST. Key points covered include the PHP lexer zend_language_scanner.l, the PHP parser zend_language_parser.y, and how an if statement is parsed and represented in the AST.
Climbing the Abstract Syntax Tree (DPC 2017)James Titcumb
The new Abstract Syntax Tree (AST) in PHP 7 means the way our PHP code is being executed has changed. Understanding this new fundamental compilation step is key to understanding how our code is being run.
To demonstrate, James will show how a basic compiler works and how introducing an AST simplifies this process. We’ll look into how these magical time-warp techniques* can also be used in your code to introspect, analyse and modify code in a way that was never possible before.
After seeing this talk, you'll have a great insight as to the wonders of an AST, and how it can be applied to both compilers and userland code.

I will show how to create an interpreter for a simple programming language using Perl 6 grammars.
This talk is not an introduction to Perl 6 regexes and grammars, so we'll use them straight on, but I will add comments so that you can understand what's going on even if you never tried Perl 6 grammars.
There will not be enough time to write the whole compiler, of course, but I will show how you can do that at home.
Most developers will be familiar with lex, flex, yacc, bison, ANTLR, and other tools to generate parsers for use inside their own code. Erlang, the concurrent functional programming language, has its own pair, leex and yecc, for accomplishing most complicated text-processing tasks. This talk is about how the seemingly simple prospect of parsing text turned into a new parser toolkit for Erlang, and why functional programming makes parsing fun and awesome.
During the talk, I will show a number of short Perl 6 fragments (mostly one-liners), that can express complex problems in a very concise way.
We will also solve a few problems from Project Euler, where Perl 6 can demonstrate its extreme beauty.

Many developers will be familiar with lex, flex, yacc, bison, ANTLR, and other related tools to generate parsers for use inside their own code. For recognizing computer-friendly languages, however, context-free grammars and their parser-generators leave a few things to be desired.

Second half of my two part series on interpreters. In this, I demonstrate how easy it is to write a very basic maths sum interpreter, including a live demo of adding a new language feature!
PHP has its own treasure chest of classic mistakes that surprises even the most seasoned expert : code that dies just by changing its namespace, strpos() that fails to find strings or arrays that changes without touching them. Do that get on your nerves too? Let’s make a list of them, so we can always teach them to the new guys, spot them during code reviews and kick them out of our code once and for all. Come on, you’re not frightening us?
Symfony2 - extending the console componentHugo Hamon
The goal of this session is to explain how to take benefit from the Symfony2 command line interface tool. First, I have a closer look at the most interesting commands to generate code and help you reduce your development time. Then, I will show you how to create your own commands to extend the Symfony CLI tool and automate your tedious and redundant tasks. This part of the talk will also explain how to create interactive tasks, interact with the database, generating links or send emails from the command line. Of course, there will be a focus on how to design your commands the best way to make them as much testable as possible.

Best practices for crafting high quality PHP apps (Bulgaria 2019)James Titcumb
This prototype works, but it’s not pretty, and now it’s in production. That legacy application really needs some TLC. Where do we start? When creating long lived applications, it’s imperative to focus on good practices. The solution is to improve the whole development life cycle; from planning, better coding and testing, to automation, peer review and more. In this tutorial, we’ll take a deep dive into each of these areas, looking at how we can make positive, actionable change in our workflow.
This workshop intends to improve your skills in planning, documenting, some aspects of development, testing and delivery of software for both legacy and greenfield projects. The workshop is made up of multiple exercises, allowing dynamic exploration into the various aspects of the software development life cycle. In each practical exercise, we’ll brainstorm and investigate solutions, ensuring they are future-proofed, well tested and lead to the ultimate goal of confidence in delivering stable software.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

astkit example usage
$if = AstKit::parseString(<<<EOD
if (true) {
echo "This is a triumph.n";
} else {
echo "The cake is a lie.n";
}
EOD
);
$if->execute(); // First run, program is as-seen above
$const = $if->getChild(0)->getChild(0);
// Replace the "true" constant in the condition with false
$const->graft(0, false);
// Can also graft other AstKit nodes, instead of constants
$if->execute(); // Second run now takes the else path

<?php
class Foo
{
private $bar;
public function thing()
{

To summarise
● For PHP engine:
○ AST is an efficient data structure to represent code
○ AST means faster compilation (ignoring opcache)
○ Separation in PHP engine for parser and compiler
○ https://wiki.php.net/rfc/abstract_syntax_tree
● Concepts can be used in userland
○ PHP Parser library - https://github.com/nikic/php-parser
○ Better Reflection - https://github.com/Roave/BetterReflection
■ Reflect on not-yet-loaded files
■ Monkey patching in userland code (!)
○ Static analysis opportunities
■ Better Reflection
■ Exakat static analysis (uses own AST)
■ Phan (uses php-ast extension)
