Set Up Routing in PHP Applications Using the Symfony Routing Component
Jul 16, 2018 @ 13:14:04

On the TutsPlus.com site today there's a new tutorial where they spotlight one of the components in the Symfony framework: the routing component. The tutorial outlines some of the basics about the component, installing it and putting it to use.

The Symfony Routing Component is a very popular routing component which is adapted by several frameworks and provides a lot of flexibility should you wish to set up routes in your PHP application.

If you've built a custom PHP application and are looking for a feature-rich routing library, the Symfony Routing Component is more than a worth a look. It also allows you to define routes for your application in the YAML format. Starting with installation and configuration, we'll go through real-world examples to demonstrate a variety of options the component has for route configuration.

The tutorial starts with the commands to get the component installed (via Composer) and other related components for YAML parsing, HTTP handling and configuration parsing. It then provides examples of:

  • setting up the instance and defining some basic routes
  • how route matching works
  • loading routes from a YAML file

The tutorial finishes with an example of an "all in one" router that pulls in the route configuration and creates a new Router instance with them ready and waiting to handle requests.

Laravel News:
Introducing View Components in Laravel, an alternative to View Composers
May 16, 2018 @ 10:55:56

On the Laravel News site there's a new post covering a refactoring of view handling that's possible with recent versions of the framework: using view components instead of view composers..

In software development, one of the “best practices” is to create reusable code that can be implemented in different parts of your application if needed. [...] View composers allow you to move the logic outside your controller and pass the data to the specified set of views. [Using view components instead of composers lets you] reuse complex components using dynamic data on any view within your application.

To help illustrate the difference they set up a scenario of a blog with a "highlights" sidebar based on data from an API response. With view composers you could extract this logic out of the controllers and add it more automatically to the view itself. They point out that this can work for a majority of the situations there's another method that is even more flexible: a reusable component implemented directly on the view. He provides the complete code showing an examples of this components, including a custom Blade directive.

Agustín Houlgrave:
A guide to a proper PHP Console Application
Feb 08, 2018 @ 11:14:28

On his Medium.com site Agustín Houlgrave has posted a tutorial with some suggestions about building PHP console applications correctly.

Googling this topic, I could only find official documentation on Symfony’s Console Component and some tutorials on quick building, but i’d like to write about making a real scalable console application that you could use in an actual production project. I’ll explain the reasons we do each of the things.

I like to write decoupled, reusable and as raw as possible code, so we’ll try to aim on that direction. Also, we’ll take advantage of all of the new features of PHP 7.

He decided on the combination of the Symfony Console Component and the Zend Service Manager to handle the use of the decoupled components. He then gets into the installation of the required packages and the initial code to create the Symfony command. He then sets up the Composer autoloading and the "factory" configuration for the command. From there he includes the code to build out the command runner and gives an example of executing the command and the output.

Zend Framework Blog:
A new release of zend-db
Dec 07, 2017 @ 10:46:48

On the Zend Framework blog today Enrico Zimuel has posted an announcement about the zend-db component including a look at the new release and the future of the component.

Today, we released zend-db 2.9.0! This is our first new feature release in over 18 months, and contains 7 bug fixes, 6 new features, numerous unit test additions, and many documentation improvements.

zend-db is an important component of many PHP projects, and we know that its support is crucial for many people. As such, we allocated a number of weeks to triaging the various open issues and patches (more than 50) to ensure we would provide a stable release.

The post lists out the issues fixed and the features added, linking to the bugs that were files related to each. It then talks about the future of the component, noting that a v3.0 release is expected to come in 2018 and will include a lot of new features. This will help to make working with more modern features of the various databases easier directly from the code (without as much manual query creation or hackery). The post finishes with some thanks to those that contributed to this v2.9.0 release.

Interview with Pawel Jedrzejewski, founder of Sylius project
Oct 24, 2017 @ 13:45:01

The Symfony blog has a new post featuring an interview with Pawe? J?drzejewski, the founder of the Sylius project - an ecommerce platform based on the Symfony components.

Sylius, an e-commerce project based on Symfony components, recently released its 1.0.0 stable version. After several years of work and thousands of commits from hundred of contributors, Sylius is now ready to take the e-commerce world by storm. We chatted with Pawe? J?drzejewski, founder and leader of the project, to celebrate this milestone.

In the interview Pawe? answers questions about the project itself, why it stands out from some of the other ecommerce projects, the state of ecommerce and why they chose Symfony components as the base for the project.

Sergey Zhuk:
Promise-Based Cache With ReactPHP
Sep 20, 2017 @ 10:11:55

Sergey Zhuk has written up a tutorial showing you how to implement promise-based caching with ReactPHP, a continuation of a previous post.

In the previous article, we have already touched caching (when caching DNS records). It is an asynchronous promise-based Cache Component. The idea behind this component is to provide a promise-based CacheInterface and instead of waiting for a result to be retrieved from a cache the client code gets a promise. If there is a value in a cache the fulfilled with this value promise is returned. If there is no value by a specified key the rejected promise returns.

He starts by defining the caching interface and how it would look in use to set/get a cache value. He shows how to update this with a "done" handler to output the value when the get is complete. He continues on showing how to use a fallback handler: either "otherwise" or "then". He also shows how these can be chained together to make more complex operations. The post ends with an example of this caching component in action and links to other library that use the same ideas.

Zend Framework Blog:
Logging PHP applications
Sep 13, 2017 @ 10:56:38

On the Zend Framework blog there's a new post in their series highlighting components of the main framework. In this new tutorial they look a the Zend-log component and how it can be used for logging in your application.

Every PHP application generates errors, warnings, and notices and throws exceptions. If we do not log this information, we lose a way to identify and solve problems at runtime. Moreover, we may need to log specific actions such as a user login and logout attempts. All such information should be filtered and stored in an efficient way.

[...] Zend Framework offers a logging component, zend-log; the library can be used as a general purpose logging system. It supports multiple log backends, formatting messages sent to the log, and filtering messages from being logged.

The tutorial then walks you through the installation of the component and some basic usage of it to write directory to the 'php://output' stream. It then shows you how to set up custom formatting on the message and a few other examples of it in use:

  • logging PHP events (errors/exceptions)
  • using the built-in data (level) filtering functionality
  • custom processors
  • working with multiple backends for storage

The post ends with a look at using the Zend-log package in either a traditional MVC application or one based more on middleware (like an Expressive application).

Symfony Blog:
The Symfony Unicorn: 1 Billion Downloads
Sep 12, 2017 @ 12:55:32

On the Symfony blog they talk about a major milestone the framework has reached: one billion downloads of the components that make up the Symfony framework.

A Symfony unicorn!!? It's real! On September 5th, the Symfony Components crossed a huge landmark: the 1 billionth download! This happened less than one year after the last milestone: 500 million downloads. That's right: the PHP community downloaded the Symfony components more than 500 million times in just one year. That's well over 1 million downloads every day!

There are so many people that have made this possible, and we would like to thank all of you who have supported Symfony: developers, contributors, companies, evangelists and - of course - users! There are now over 80 Symfony packages and 1,500 people have contributed code to these. None of this is possible without your help. Congrats!

The post then talks about the current state of the components (including their download numbers), their backwards compatibility promise and how it relates to the upcoming Symfony 4 release.

Introduction to Latte | Best PHP templating engine
Aug 17, 2017 @ 11:30:15

On the Omniceps site there's a new post introducing you to Latte, the templating component of the Nette framework that can be used independently.

A PHP templating engine is the one which gives you ability to write html for your clients efficiently using PHP variables.

However, PHP was originally built to be a templating engine, but yet it was never used primarily as a templating engine. There has been so many PHP templating engine so far in the market since PHP evolved, but none of them has made as great impression on us as Latte. Introducing you to Latte, one of the best PHP templating engine you have come across so far. Also Latte protects your web app from vulnerabilities like XSS (cross site scripting).

The tutorial starts with an example comparing "plain old PHP" templating with the Latte version for a foreach loop. Next they show how to install the Latte component and the two different kinds of macros the tool includes. They also talk about filters, performance concerns, context aware escaping and "pretty output" options.

Zend Framework Blog:
REST Representations for Expressive
Aug 09, 2017 @ 10:12:18

On the Zend Framework blog there's a new post from project lead Matthew Weier O'Phinney covering REST representations in Expressive and the release of two new components to help with their implementation.

We've been working towards our various Apigility on Expressive goals, and have recently published two new components: zend-problem-details and zend-expressive-hal.

These components provide response representations for APIs built with PSR-7 middleware. Specifically, they provide: Problem Details for HTTP APIs (RFC 7807) and Hypertext Application Language (HAL).

These two formats provide both JSON and XML representation options (the latter through a secondary proposal).

The post then goes on to talk about the idea of "representations" and how it relates back to the structure of the data returned and how the user knows what operations they can take on it. He also talks about the differences between normal responses and errors and gives example output helping to illustrate his points. The remainder of the post gets into the details of the two new components, their use and how to implement them in Expressive.
