GENERAL DB IMPROVEMENTS
- Added an optional parameter that allows to disable escaping (useful for custom
ﬁelds) for methods join(), order_by(), where_in(), or_where_in(), where_not_in(),
or_where_not_in().

- Added support for join() with multiple conditions.

- Added support for USING in join().

- Changed limit() to ignore NULL values instead of always casting to integer.

- Changed offset() to ignore empty values instead of always casting to integer.

- Added 'dsn' conﬁguration setting for drivers that support DSN strings (PDO,
PostgreSQL, Oracle, ODBC, CUBRID).

MYSQLI DB IMPROVEMENTS
- OOP style of the PHP extension is now used, instead of the
procedural aliases.

- Server version checking is now done via MySQLi::$server_info
instead of running an SQL query.

- Added persistent connections support for PHP >= 5.3.

Puppet is an open source tool used to automate server configuration management. It ensures servers are configured and packages installed as defined. Puppet manages configuration through resources like packages, files, users and more. It can install packages, configure files and folders, manage services, create users/groups, and run commands. Puppet applies configurations idempotently so they can be run multiple times without changing the server unless the configuration changes.

Advanced symfony TechniquesKris Wallsmith

Go beyond the documentation and explore some of what's possible if you stretch symfony to its limits. We will look at a number of aspects of symfony 1.4 and Doctrine 1.2 and tease out some powerful functionality you may not have expected to find, but will doubtless be able to use. Topics covered will include routing, forms, the config cache and record listeners. If you're comfortable in symfony and wondering what's next, this session is for you.

PHP MVCReggie Niccolo Santos

The document discusses the Model-View-Controller (MVC) pattern, which separates an application into three main components: the model, the view, and the controller. The model manages the application's data logic and rules. The view displays the data to the user. The controller handles input and converts it to commands for the model and view. An example PHP MVC application is provided to illustrate how the components work together. Benefits of MVC include flexibility, testability, and separation of concerns between the three components.

Speed up your developments with Symfony2Hugo Hamon

Symfony2 is a PHP full-stack framework that provides tools and components to speed up web development. It emphasizes separation of concerns, standards compliance, and best practices. Symfony2 allows developers to create Request-Response applications using its routing, templating, validation, forms, database abstraction, and other features in a decoupled and reusable way. It also provides debugging tools, code generators, and other utilities to improve developer productivity.

Powerful and flexible templates with Twig Michael Peacock

Twig is a template engine for PHP that allows developers to create powerful and flexible templates. It provides features like template inheritance, blocks, variables, filters, tags, and loops to integrate dynamic content. Templates can extend a base template, override blocks, and include other templates. Variables passed to templates can be accessed and filtered. Developers can also extend Twig with custom filters and functions.

“Use the right tool for the right job” is one of the first thing they teach you when you start out in these waters. I would make “Get to really know your tools” a second. In this talk we’re going to work on the architecture of an app that showcases some common features/scenarios we all probably already have in the apps we’re working on: counters, leaderboards, queuing, timelines, caching. But this time we’ll implement them with Redis, making the apps much faster, your hardware (and you) much cooler, your boss (and the clients) much happier and hopefully your salary a bit higher.

Codeigniter : Two Step View - Concept ImplementationAbdul Malik Ikhsan

This document describes implementing a two-step view concept in CodeIgniter by using output buffering. It involves three main components: 1) an initialization hook to start output buffering, 2) a helper to generate the two-step view content and load it into a layout view, and 3) a layout view to echo the content. The helper gets the buffered content, loads a view to generate the content string, loads the layout view and passes the content, and the layout view echoes the content within the HTML structure. This allows separating view generation and rendering for a cleaner separation of logic and presentation.

Head First Zend Framework - Part 1 Project & ApplicationJace Ju

Zend Framework provides tools for creating PHP web applications. The zf script is used to generate a project skeleton and configure resources. The Zend_Application loads configuration from application.ini, initializes the bootstrap class, and runs the application. The bootstrap class initializes custom resources. Common resources like the front controller, database, and view are initialized through Zend_Application_Resource classes, which get configuration options from application.ini. This allows flexible configuration and initialization of an MVC application in Zend Framework.

ACL in CodeIgnitermirahman

This document discusses using CodeIgniter hooks to implement access control lists (ACL) for authorization instead of hardcoding checks in controllers. It describes how to define a pre_controller hook that checks user permissions against defined roles and redirects unauthorized users. An Accesscheck class and permissions array centralize the ACL logic, allowing role-based access control without modifying core files. This provides a simpler, more flexible alternative to ACL implementations in other frameworks.

Consuming RESTful services in PHPZoran Jeremic

Here are the key steps to load data from a RESTful service using AJAX and jQuery: 1. Make an AJAX GET request to the REST API endpoint using jQuery.ajax() or jQuery.getJSON(). 2. Specify the URL, set the data type to "json", and provide a success callback. 3. On success, the JSON response will be passed to the callback function where it can be used to update the UI. 4. Parse the JSON response into a JavaScript object for easy access to the data. 5. Update the HTML using the jQuery DOM manipulation methods like html(), text(), etc. So in summary - make an AJAX GET, parse the JSON response,

ASP.NET Web API and HTTP FundamentalsIdo Flatow

ASP.NET Web API is the de facto framework for building HTTP-based services in the .NET ecosystem. With its WCF and MVC lineage, Web API brings to the table better architecture, easier configuration, increased testability, and as always, it's customizable from top to bottom. But to properly use Web API it is not enough to get familiar with its architecture and API, you also need to really understand what HTTP is all about. HTTP is the most common application layer protocol in the world, and yet, not many web developers are familiar with HTTP concepts such as of chunking, caching, and persisted connections. In this full-day tutorial, we will focus on designing and implementing HTTP-based services with ASP.NET Web API, and you will learn how to better use it to implement the features provided by HTTP.

The Art Of Readable CodeBaidu, Inc.

The document discusses techniques for writing readable code, including: - Code should be easy for others to understand by using clear naming conventions, comments only where needed, and simple control flow. - Surface-level readability can be improved through specific and unambiguous naming, consistent formatting, and avoiding overly long or generic names. - Loops and logic should read like natural language to make the flow of execution easy to follow. This includes ordering conditional statements positively first and breaking down complex expressions. - Code can be made more scannable through proper indentation and grouping of related lines together into blocks. Overall the goal is to minimize the time it takes someone new to understand the code.

Burn down the silos! Helping dev and ops gel on high availability websitesLindsay Holmwood

HA websites are where the rubber meets the road - at 200km/h. Traditional separation of dev and ops just doesn't cut it. Everything is related to everything. Code relies on performant and resilient infrastructure, but highly performant infrastructure will only get a poorly written application so far. Worse still, root cause analysis in HA sites will more often than not identify problems that don't clearly belong to either devs or ops. The two options are collaborate or die. This talk will introduce 3 core principles for improving collaboration between operations and development teams: consistency, repeatability, and visibility. These principles will be investigated with real world case studies and associated technologies audience members can start using now. In particular, there will be a focus on: - fast provisioning of test environments with configuration management - reliable and repeatable automated deployments - application and infrastructure visibility with statistics collection, logging, and visualisation

API Pain Points (PHPNE)Phil Sturgeon

I've been building APIs for a long time now and it is becoming ever more common for server-side developer thanks to the rise of front-end JavaScript frameworks, iPhone applications and generally API-centric architectures. On one hand you're just grabbing stuff from a data source and shoving it out as JSON, but surviving changes in business logic, database schema updates, new or deprecated etc gets super difficult. This talk will outline the common pitfalls developers get trapped in when building APIs and outline methods to avoid them, including naming stuff badly then having to rename everything, when and how to use POST/PUT/PATCH, data structures, DDoSing yourself because pagination, picking your authentication system and all sorts of other stuff.

PHP-FIG: Past, Present and FuturePhil Sturgeon

In 2009 the PHP-FIG created PSR-0: an autoloading standard that helped to change the landscape of PHP forever, thanks in no small part to its integration with Composer. Well, PSR-0 was built in a land before PHP had namespaces, when Horde and PEAR were prevalent and Composer was but a twinkle in the eye of two developers. In December 2013 PSR-4 was released as a newer, shinier version of that standard. The FIG has more standards happening, some of which may be out just in time for this talk.

Become Master of Your Own Universe - DIBI 2013Phil Sturgeon

Being a developer for years its very easy to get type-cast. You become "The CodeIgniter Guy", the one dev in the office that knows how FooCMS works or just end up farming out CRUD day after day. Well I decided to say "nope" to that & accepted a job where I'd need to know how to do…everything. This talk aims to give you an overview of what you should be looking to learn next if you want to stop being "just a developer" & move into the devops/architecture arena.

Laravel and ComposerPhil Sturgeon

Composer is moving over to use Laravel, which requires command line stuff and a bunch of new thinking as to how code is managed. Also, my bundles have vanished, and now we're using camelCase instead of snake_case? Sit down for a history lesson about why packages have always been a mess, why frameworks have been the way they were and why they're changing in this "PHP Renaissance" to use awesome new tools like Composer.

Why I <3 Laravel 4Phil Sturgeon

Laravel 4 is a PHP framework that leverages Symfony components and follows PSR-2 standards. It requires PHP 5.3 and uses features like dependency injection and Composer. While CodeIgniter is easy to learn, Laravel 4 has a larger community and more addons available. The framework has evolved over time from CodeIgniter and Kohana to Symfony and now Laravel 4, which stays lightweight while providing flexibility.

Cms expoPhil Sturgeon

Phil Sturgeon created PyroCMS as an open-source CMS to address issues he encountered building websites for non-technical clients. PyroCMS is built using CodeIgniter and PHP for easy installation, uses tags for simple content management, and has an intuitive interface requiring no training.

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock

Building 10x Organizations with Modern Productivity Metrics 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?
