Dutch Web Alliance: Capifony, Continuous Deployment and Symfony's parameter.yml

On the Dutch Web Alliance site today they've posted a tutorial about their use of Capifony for Symfony application deployment and how it relates to updating the "parameter.yml" file. They describe their current deployment process, how it works with the different environments and how they solved the one manually problem they had.

The actual deployment is thus dealt with by capifony. This is a plugin for capistrano written for deploying Symfony applications. [...] Capifony automatically deals with cloning the correct branch on the servers, installing dependencies through composer, migrating database versions etc etc. Basically we don't have to care about anything else. However, there is one single thing that still keeps on bugging us: when we want to upgrade to a new parameters.yml, we must do this manually. This means that our builds will break when we deploy a version that requires an updated parameters.yml until we manually solve the issue.

To get around this manual issue, they decided on creating a new Capifony task that does an upload/download of the parameters file, depending on the environment.The continuous deployment can then push or pull the file as needed in a more automatic way.

SitePoint PHP Blog: Writing API Documentation with Slate

The SitePoint PHP blog has a new tutorial for the API developers out there showing you how you can use Slate for creating documentation. They point out a few other tools or formats you could use, but focus in on Slate, a Markdown-based tool that converts the result to HTML.

So you've built yourself an API. Perhaps it's RESTful, RESTlike or something else entirely. [...] There's one more thing, however. Thing is, an API is only as good as its documentation. That applies if it's for internal use only - perhaps it's for a JavaScript-based one-page app, or a mobile application - but even more so if it's for public consumption.

He includes an example of what the output looks like first so you know what the end result will be (and if it meets your needs). They then walk you through the installation of Slate and a few Ruby tools you'll need to generate the HTML output. He includes a simple example of the configuration and a simple document with four sections. He also shows how to use includes, alerts, tables and a sidebar. Finally he gives the "rake" command to build the documentation and how to you can push the result up to your own GitHub Pages.

Rob Allen: Overriding the built-in Twig date filter

In his latest post Rob Allen shows a way you can override the default Twig date filter with your own custom Date extension handling.

In one project that I'm working on, I'm using Twig and needed to format a date received from an API. The date string received is of the style "YYYYMMDD", however date produced an unexpected output. [...] This surprised me. Then I thought about it some more and realised that the date filter is treating my date string as a unix timestamp. I investigated and discovered the problem in twig_date_converter.

He includes some example code you'll need to create the custom renderer. As part of the internals of how Twig formats the date currently is internal and can't be changed, he opted to override the extension itself. As a result, the call to the filter is exactly the same as before, the output results are just formatted more correctly.

Erika Heidi: The Art of Programming

Erika Heidi has posted an interesting article on Mdeium.com today with a look at the art of programming, relating the work we as developers do back to the same kinds of skills artists use in their work.

One of the most consolidated misconceptions about programming, since the early days, is the idea that such activity is purely technical, completely exact in nature, like Math and Physics. Computation is exact, but programming is not. The first is a result of a machine operation, and the latter is still a human activity.

Programming requires a lot of creativity, on top of the abstract concepts, tools and techniques that we might learn in a classroom; all that theory represents only a tiny portion of what is necessary to build a great developer.

She talks about some of her own past experiences with programming and how, from even simple beginnings, she had a "mind blowing experience" making something from just a few lines of code. She talks about how she sees similarities between programming and art such as the two kinds of artists: the ones that copy other work, recreating things already made and the genuine artists making new and inventive things.

Respect the work of others, even if you think there is something with a similar purpose already out there. It's their expression. They are not trying to reinvent the wheel. They are trying to create a better wheel, or a wheel that works better for their purposes.

SitePoint PHP Blog: AngularJS in Drupal Apps

On the SitePoint PHP blog there's a new tutorial posted (by Daniel Sipos) about combining Drupal and AngularJS to make for more front-end focused, responsive applications.

Angular.js is the hot new thing right now for designing applications in the client. Well, it's not so new anymore but is sure as hell still hot, especially now that it's being used and backed by Google. It takes the idea of a JavaScript framework to a whole new level and provides a great basis for developing rich and dynamic apps that can run in the browser or as hybrid mobile apps. In this article I am going to show you a neat little way of using some of its magic within a Drupal 7 site. A simple piece of functionality but one that is enough to demonstrate how powerful Angular.js is and the potential use cases even within heavy server-side PHP frameworks such as Drupal.

He walks you through the creation of a simple addition of a block that lists out the titles of some other nodes. You'll need an existing Drupal installation to follow along (no setup instructions here) as well as an Angular structure for a small application. He starts with the module configuration and creates custom handling to return the JSON result back to the waiting JS connection. Then he creates the custom template and block that the AngularJS will output the results too. Finally, with that rendering, he glues them both together in an Angular controller that loads the results when an "Open" button is clicked.

Sameer Borate: Integrating Googles new reCAPTCHA in PHP

Recently Google announced their reCAPTCHA without a CAPTCHA technology to help make preventing automated systems (usually spammers) from causing issues in your applications. In this new post from Sameer Borate, he shows you how to implement this new kind of CAPTCHA in your PHP-based application.

For the past several years Google's reCAPTCHA has helped verify that a user is not a bot by forcing you to decipher warped text. reCAPTCHA's method of protecting websites from spam has always been a kind of burden on the end user who has to solve the captcha to prove that he is human and not a bot. [...] Google recently released a new captcha API called "No CAPTCHA" reCAPTCHA, which utilizes an Advanced Risk Analysis engine that is capable of discerning between users and bots. So instead of solving a jumbled box of text all a user has to do is check a box.

He walks you through the full process of the integration:

  • Signing up for an account/API keys
  • Rendering the HTML for the actual widget (using Google Javascript)
  • Validating the user's response via an API call
  • The PHP you'll need to perform the validation

He also briefly mentions some of the customization available and provides the code as a download so you can see it all working together.

NetTuts.com: Integrate Bitcoin Payment Gateway Into OpenCart: Part 1

On the NetTuts.com site today they've posted the first part of a series showing the integration of the BitPay bitcoin payment service into an OpenCart instance. In this first part they focus on getting some of the initial setup and administration handling set up.

In this series, we are going to look at building a Bitcoin payment system into our installation of OpenCart. Before we get started, I recommend that you practice the basic OpenCart module development if you are not familiar with how to build your own modules. Once done, you should have enough knowledge to continue with developing more advanced modules. In this series, that's exactly what we aim to do.

They start by having you download the BitPay API library and dropping it into the root directory of your OpenCart installation. Next they show you how to create an "Admin" controller with the data you'll need to pass into the view including data pulled from a model. They also create the admin view showing the current orders using bitcoin as payment, their status and options to change the speed of the API requests, status and toggling test mode on and off. Finally they include the code to save the results of the admin form submission and a bit of validation around user permissions and API key validity.

Symfony Blog: Testing minimal versions of Symfony requirements

On the Symfony blog today there's a quick tip from Nicolas Grekas about using Composer to install a Symfony2 project and the definition of minimum version requirements.

Setting up Composer package versions for complex projects is not an easy task. For starters, there are a lot of different ways to define package versions. Then, you must check that declared package versions really work when installing or updating the project, specially for the minimal versions configured. In order to improve testing the minimal versions of Symfony Components requirements, Composer now includes two new options: prefer-lowest and prefer-stable. [...] Thanks to these two new options, it's really easy to check whether your project really works for the minimal package versions declared by it.

He includes definitions of what impact each of the options has on the packages Composer installs and the work that's been done recently to define the correct package versions for the 2.3, 2.5 and 2.6 branches of Symfony. He also offers some steps to follow in your own projects to ensure that the "prefer-lowest" packages installed work correctly.

SitePoint PHP Blog: Getting Started with Medoo - Examples of Use

On the SitePoint PHP blog, there's a new tutorial that introduces you to the Meedoo library, a tool to make working with databases even easier. In this tutorial Wern Ancheta walks you through some of the basics of the tool and shows you how to use it with a Pokemon-based example.

In this article I'm going to walk you through Medoo, a lightweight database abstraction library for PHP. Its main features include: support for multiple databases, being secure and easy to use. [...] While Medoo is nothing revolutionary, and the fact that it sports a very small filesize matters little to few, it's still an interesting project that went from being outright dismissed to vaguely accepted, as evident in these threads. It's on its way up, and that's our reason for taking a look at it.

Once installed (he recommends using Composer) you can follow along with his examples showing how to connect to the database, make a simple select and define something a bit more complex (like multiple other requirements in the SQL statement's "where"). He shows how to execute manual queries and handling more complex operations like joins. He then gets into the other parts of the usual CRUD handling - inserting new data, updating data and deleting data.He finishes the post by mentioning aggregate functions and some of the debugging options the tool includes.

Recently the "prefer-lowest" option of Composer was mentioned in relation to testing for Symfony-based applications. In this new post to his site Matthieu Napoli shows how you can do it on any project that uses the Travis-CI continuous integration service.

Composer just got a new awesome addition thanks to Nicolas Grekas: prefer the lowest versions of your dependencies. [...] This amazing option will install the lowest versions possible for all your dependencies. What for? Tests of course!

He includes all the instructions you'll need to get your Travis build using this command line option, starting with testing it on your own system first. He shows a basic ".travis.yml" file with the configuration you'll need to provide it use the "prefer-lowest" (check out line 17). He does point out that you'll need to run a "composer self-update" first though, as Travis hasn't quite caught up with the latest Composer that includes this option.

Lee Blue: How PHP Frameworks Affect Profitability

Lee Blue has posted his next article in a series covering some of the real costs and considerations around using PHP for your applications. In this latest post he talks about frameworks and what kind of effect they could have on the overall profitability of your business.

Last week we talked about application shelf life an aspect of PHP development that often goes overlooked. This week let's talk about how the web development framework you use contributes to the shelf life of your app and the profitability of your web application. [...] The main goal of all web frameworks is to improve the developer's ability to get ordinary things done so we can focus on the primary goals of what we're building.

He talks about how PHP was "made for the web" and why there are so many different kinds of frameworks out there (though most are generally MVC-ish). He talks about one of the standard arguments, learning curve vs efficiency, and how it compares to the "no framework framework" ideals. He then gets into some of the dark side of using frameworks, specifically how they can shorten the shelf life of an application and how difficult migration can sometimes be. He points out the irony of large frameworks: the bigger the app/framework, the harder it can be to migrate (and cost more). He encourages sticking with smaller, lighter frameworks instead and suggests coding standards, common packages and using custom libraries only where needed to create your application.
