Zend Framework Blog:
Manage your application with zend-config-aggregator
Apr 20, 2017 @ 16:09:14

The Zend Framework blog has a new post sharing a method for managing your application's configurations with the help of the zend-config-aggregator package, a product of work on the Zend Expressive framework.

With the rise of PHP middleware, many developers are creating custom application architectures, and running into an issue many frameworks already solve: how to allow runtime configuration of the application.

configuration is often necessary, even in custom applications. [...] Faced with this reality, you then have a new problem: how can you configure your application, as well as aggregate configuration from other sources?

As part of the Expressive initiative, we now offer a standalone solution for you: zend-config-aggregator

The post walks you through the installation of the package and introduces some of the included configuration providers. The tutorial then shows how to put the component to use, aggregating several different kinds of configuration files. It also shows how to use caching on the results and auto-enabling third party and custom providers.

Zend Framework Blog:
Create RSS and Atom Feeds
Apr 13, 2017 @ 12:47:01

In a previous post to the Zend Framework blog Matthew Weier O'Phinney talked about parsing feeds with Zend Framework components. In this latest post they cover the other half of the equation - creating RSS and Atom feeds using some of the same components.

In our previous article on zend-feed, we detailed RSS and Atom feed discovery and parsing. Today, we're going to cover its complement: feed creation!

zend-feed provides the ability to create both Atom 1.0 and RSS 2.0 feeds, and even supports custom extensions during feed generation. [...] You can also provide your own custom extensions if desired; these are just what we ship out of the box! In many cases, you don't even need to know about the extensions, as zend-feed will take care of adding in those that are required, based on the data you provide in the feed and entries.

He then shows how to pull in the zendframework/zend-feed component and how to use it to create a simple RSS feed with a title, link, description and "feed link". He then shows how to add new items to the feed (with details for each item) and how to render the resulting feed.

Zend Framework Blog:
zend-config For All Your Configuration Needs
Feb 23, 2017 @ 10:25:13

The Zend Framework blog has a new post from Matthew Weier O'Phinney focusing on another useful component of the framework, the zend-config component. This component, already in wide use across the framework, allows for flexible configurations to be defined and easily consumed for your use.

Different applications and frameworks have different opinions about how configuration should be created. Some prefer XML, others YAML, some like JSON, others like INI, and some even stick to the JavaProperties format; in Zend Framework, we tend to prefer PHP arrays, as each of the other formats essentially get compiled to PHP arrays eventually anyways.

At heart, though, we like to support developer needs, whatever they may be, and, as such, our zend-config component provides ways of working with a variety of configuration formats.

He walks you through the installation of the component (via Composer) and the dependencies it requires. The post then moves on to the use of the component to get configuration values from a single or multiple files (.php, .ini, .json, etc). It also covers the optional return of the values as objects, making them read-only, including your own configurations and using alternative parsers (like Symfony's YAML component). It ends with a look at some of the configuration options you can give the component including the addition of processors to manipulate values once they're read.

Rob Allen:
Stand-alone usage of Zend-InputFilter
Feb 15, 2017 @ 09:58:51

Rob Allen has written up a brief tutorial showing you how to use the Zend/Filter component independently from a Zend Framework application. In his example he integrates it into a simple API endpoint.

Any data that you receive needs to be checked and validated. There are number of ways to do this including PHP's filter_var, but I prefer Zend-InputFilter. This is how to use it as a stand-alone component.

He shows you how to get the component installed (along with the Zend ServiceManager) and the creation of a basic validation/filtering on "author" data. He explains the different parts that make up the instance: required, filters and validators. He then shows how to use it in your request and the resulting output if something fails.

Matthias Noback:
Introducing the SymfonyConsoleForm package
Jan 20, 2017 @ 11:12:51

In a new post to his site Matthias Noback introduces you to a package that can help you in your Symfony-based console application, combining the Form and Console components, to make it easier to create "forms" on the CLI.

About 2 years ago I created a package that combines the power of two famous Symfony components: the Form component and the Console component. In short: this package allows you to interactively fill in a form by typing in the answers at the CLI. When I started working on it, this seemed like a pretty far-fetched idea. However, it made a lot of sense to me in terms of a the package in use, building a "form" that just asks the user to input a name. An image of the result is included as well. He ends the post with some of his other general findings during the process of creating the package and suggests a few common use cases including installation wizards that can be used in both the CLI and web interfaces.

Zend Framework Blog:
Implement an XML-RPC server with zend-xmlrpc
Jan 18, 2017 @ 14:22:33

As a sort of follow up to their previous article showing the use of the zend-json-server component to create an XML-RPC service, the Zend blog is back with a different take on the same functionality, this time using zend-xmlrpc.

zend-xmlrpc provides a full-featured XML-RPC client and server implementation. XML-RPC is a Remote Procedure Call protocol using HTTP as the transport and XML for encoding the requests and responses.

[...] Each XML-RPC request consists of a method call, which names the procedure (methodName) to call, along with its parameters. The server then returns a response, the value returned by the procedure.

The post walks you through an example request/response flow and some of the value types allowed in the XML-RPC structure. From there it's on to the code, creating the simple server and an "add" method on the "calculator" service. The post then covers how to integrate this setup with the zend-mvc component and an application based on it. It finishes up with an example of the same kind of functionality only applied in a PSR-7 middleware instead.

Laravel News:
Laravel Blade Components and Slots are coming to 5.4
Nov 16, 2016 @ 10:46:54

On the Laravel News site there's a post about an upcoming feature in the Laravel framework's Blade templating functionality: components and slots.

A new feature coming to Laravel 5.4 is the ability for you to add Components and Slots to Blade templates. This feature was inspired by Vue.js and allows you to simplify building HTML elements into reusable areas.

In most applications you have a master layout and then sub views that extend it. [...] Using the new Laravel Blade Components you can create [a template] with a special variable [for easy replacement].

The post then shows how to "reimagine" views using this slots and components functionality in a simple template/view example, replacing data based on names rather than it having to be passed to the view as data.

Stomt Blog:
Shared Components Across Multiple Laravel/Lumen Micro-Services
Oct 21, 2016 @ 12:19:30

On the Stomt blog today there's a post showing how you can share components across Laravel/Lumen applications using a simple structure and making things like microservices easier.

In this blog post, we show a way to split up large Laravel applications into smaller micro-services, in our case Laravel & Lumen applications, and the advantages and pitfalls it brings with it. As a result, we sped up our applications by more than 30% and achieved greater maintainability, too. These principles can, of course, be easily applied to other frameworks.

A lot of functions are needed in our REST API as well as in our administration panel. [...] While we still have a “monolithic” codebase, we have multiple completely independent backend applications. You might want to call them “micro-services” (because it’s so trendy).

These microservices required similar functionality and splitting those out into shared components made sense. They walk you through some of the basic requirements they had when splitting the application and how the components are structured. They then shift over to the Laravel/Lumen side and show how multiple applications can be hosted via the same installation and where the shared components fit in. They show how to define namespaces to load the components and set up the providers so Laravel/Lumen knows how to use them.

Eleven Labs:
Use the Symfony Workflow Component
Sep 29, 2016 @ 11:21:42

The Eleven Labs site has a new tutorial posted showing you how to use the Symfony workflow component, a component designed to help make performing a sequence of operations simpler.

Since Symfony 3.2, a new useful component was born: the Workflow component.

It is indeed really convenient and can simplify greatly your developments when you have to manage status workflows in your application, that occurs a lot.

The tutorial starts by helping you get the Workflow component installed (via Composer) and an example configuration defining a flow for a pull request. They then show the command to generate the flow graph so you can ensure the workflow is correct. From there example code is provided to use the workflow and do things like:

  • checking if you can transition to a certain state
  • get the list of enabled transitions
  • event handling

Code examples and configuration options are also included for these points, helping you to make your workflow even more flexible.

Yappa Blog:
Symfony Components in a Legacy PHP application
Jun 21, 2016 @ 12:50:13

On the Yappa Tech blog Joeri Verdeyen has written up a post covering the integration of modern Symfony components into a legacy application with a relatively simple container setup and configuration.

Symfony Components are a set of decoupled and reusable PHP libraries. They are becoming the standard foundation on which the best PHP applications are built. You can use any of these components in any of your applications independently from the Symfony Framework.

[...] The purpose of this post is to roughly describe how to implement some of the Symfony Components. I've created a set of gists to get started. You should already know how Symfony Components work in the Symfony Framework.

He starts with an example Composer configuration pulling in some of the more popular Symfony packages (like VarDumper and FormBuilder). He then includes the code to bootstrap the container instance and the services.yml he's come up with to bootstrap and integrate all of the components. The tutorial ends with examples of putting some of these components to use in resolving controllers, using the FormBuilder, using the command line and outputting errors with the VarDumper.
