Inspecting PHP Code Quality with Scrutinizer
April 29, 2015 @ 11:24:24

The SitePoint PHP blog has a recent tutorial showing you how to use the Scrutinizer service to evaluate the quality and "pain points" in your PHP code, be it a library or full application.

We've gone through a decent number of tutorials about code quality, inspections, auto-build systems and so on here at SitePoint. [...] In this article, we'll take a look at Scrutinizer CI - a continuous integration tool that's quite expensive and closed to private projects, but very handy for public ones.

He starts with a quick comparison of Scrutinizer versus (and really plus) the popular CI service Travis CI. He then walks you through the setup of Scrutinizer to evaluate your application automatically when code is pushed to GitHub. He then gets into the configuration options the service provides including filters, specific checks to evaluate and other tools to execute in the evaluation build. The article then gets into examples of the reports that are provided and a bit of detail about what each view provides. There's also options to hide certain errors that you know aren't actually problems and the "follow up" links it provides for the issues you may not understand.

Piotr Pasich:
Ant, composer and code quality tools
March 18, 2015 @ 11:33:47

In his latest post Piotr Pasich shares some handy tips (and tools) to help you use Composer to do some of the common tasks you might use Ant or Phing for.

I decided to start with something uncomplicated - a simple solution that could help me solve a prosaic, but annoying issue. For instance, XML format. No, I won't fight with it. I see it as great and practical, however mostly I don't need so sophisticated code to cover my needs - the yaml usually fits the purpose. [...] Yet, do I really need this flexibility [of XML configuration] when I use vagrant or docker to maintain the same environment as on the production? For 90% of PHP projects probably I won't use all of the features of the virtualization tools. I only want to install necessary libraries, check the code quality before committing or introduce fixtures. Most of those points are easily feasible in composer.

He then shows how to execute these checks through the functionality included with Composer to run custom scripts. His example measures the quality of the code based on the results first from a single run of the PHP Mess Detector (phpmd) command. He then extends this with the open source contribution he mentions earlier with his CodeQualityThreshold library allowing not only for more checks (phpmd, phpcs, phpcpd, etc) but also allows you to configure the thresholds for each class if desired. He includes an example of it in action and screenshots of the results.

Dave Marshall:
Probing Test Suite Quality with Mutation Testing
January 08, 2015 @ 12:09:42

In this recent post to his site Dave Marshall looks at a method for evaluating the overall quality of your suite of unit tests with help from mutation testing.

100% code coverage should never really be a goal. [...] I feel pursuing 100% coverage in a PHP project is a particularly poor idea as our tooling generally only provides Line Coverage. [...] There are more reasonable coverage metrics to use to measure the quality of a test suite. Sebastian Bergmann and Derick Rethans are working hard on bringing some of these options to us, but for now we're limited to line coverage.

He talks about the difference between line, branch and condition coverage types (with code examples) and which allows for more effective and quality tests to be written. He then talks about the results of an experiment to achieve 100% coverage on the Router component in the Aura project. He found the problem using mutation testing - changing values in the production code to make sure the tests break. He also links over to a new mutation testing tool that's been released to help with this kind of thing, humbug, and some of the results it can report.

Mutation testing is a great thing to have a grasp of in theory, but it's not particularly easy to practice. The tools are very hard to write and then their output is often hard to understand or interpret effectively. I wouldn't recommend practicing with mutation testing on a regular basis, but it's certainly worth considering on the odd occasion.

SitePoint PHP Blog:
Visualize Your Code's Quality with PhpMetrics
December 26, 2014 @ 12:48:31

The SitePoint PHP blog has a recent tutorial showing how to use PhpMetrics to visualize your application and the quality of its code.

We had been looking into code quality checking tools for a while here on SitePoint - most recently in a series on Jenkins, but none of those could do what a project I've only recently found out about can. PhpMetrics uses D3 and some sophisticated analysis algorithms to scan your application's code and output intricate reports about it.

He walks you through the install (via Composer) and how to clone two example projects, Laravel and Symfony, to evaluate. He includes the command line to run the evaluation and plenty of screenshots showing the results for things like:

  • Cyclomatic complexity
  • Abstractness
  • Maintainability
  • Code density

He uses the results from these two projects in his examples and, at the end of the post, summarizes and compares the results it produced.

SitePoint PHP Blog:
Check Your Code's Quality with SensioLabs Insight
August 07, 2014 @ 12:25:20

On the SitePoint PHP blog today there's a new post by Peter Nijssen introducing you to the SensioLabs Insight service and how it can improve your code quality (including locating security concerns).

The quality of your code is as important as testing your application. Recently, we have seen multiple articles which hopefully helped you on your way to providing a more stable application. Today, we are going to have a closer look at SensioLabs Insight. If you used Symfony or Silex in the past, you are probably familiar with SensioLabs, since they are the main sponsor of the Symfony framework.

He quickly introduces the service, mentioning what it has to offer and how to get your account all set up (free for open source libraries but it requires the results to be public). He includes some screenshots showing what the setup and scan results of your project might look like. He shows how to get more detail on the findings and how they can easily be exported to your bug tracker for fixing. He also covers some of the configuration you can do (through a YAML file) to tell Insight things like: php.ini settings, directories to exclude and specific rules to run during the scans.

Expert Developer:
Install PHP CodeSniffer on Windows Machine
July 29, 2014 @ 10:33:45

On the Expert Developer site there's a new tutorial showing you how to get the PHP CodeSniffer tool up and working on a Windows installation. PHP CodeSniffer provides functionality to enforce standards and best practices in your application's development (providing code quality).

In this article we will focus on improving Code Quality. Very first step towards improving code quality is to maintain coding standards across developers. [...] Here we will talk about PHP CodeSniffer, which help us to maintain coding standard across multiple developer. Dealing with CodeSniffer is much easier: create rule set, validate your file against your rule set and get the result immediately. It will immediately show how many mistakes you have made in terms of following coding standards and eventually all developer will start coding as per coding standards you have defined.

There's two main parts to the article: first is getting PEAR installed (a package manager for PHP) and then using it to install CodeSniffer. Complete instructions and commands are included as well as a few screenshots along the way.

Codeacy Blog:
Your Greatest Code Quality Threats and How to Solve Them
June 23, 2014 @ 09:22:42

On the Codacy blog there's a recent post that looks at some of the biggest threats to code quality (six of them) and some brief advice on how you can prevent them. Code quality goes beyond just style guides and common coding practices too.

In the process of building Codacy, I've learned that software companies in different life stages have different needs in terms of code quality. Early startups have, for example, very different needs in comparison to digital agencies and freelancers. There is however a common ground that links them all together: code quality is not being taken seriously enough, regardless of the stage. If this resonates with you, take action today. Continuous improvement is the central piece of software engineering craft.

Among the six things in their list are suggestions like:

  • Using continuous integration
  • Living with broken windows
  • Heterogeneity (code styles)
  • Not using static code analysis

They also link to some tools that can help fix some of these suggestions including JSHint, some PHP static analysis tools and CSSLint for CSS.

Review of PHP Static Analysis Tools
May 09, 2014 @ 11:35:15

The Codacy.com blog has posted a review of various static analysis tools for PHP-based applications. These tools can help provided quality and consistency in your code in a more automated way.

Maintaining code quality over time is a hard challenge. It becomes even harder in large projects developed by many programmers. Each person has different code styles and different ways to approach problems. Over time, this may result in confusing and unmaintainable code. Static analysis tools can help developers solve this problem, they enforce coding standards, detect common errors and cleanup code blocks.

Tools mentioned in the post include: PHP_CodeSniffer, the PHP Mess Detector and the PHP Copy & Paste Detector. Each comes with an example of the command to execute it and some sample results. They also talk briefly about where and how these tools could fit into your current workflow, either during development or as a part of a full deployment process.

Reddit.com:
Can anyone suggest a php ecommerce solution that isn't terrible?
March 28, 2014 @ 12:56:42

Over on Reddit.com there's a good discussion (with plenty of feedback) to a user looking for "a PHP ecommerce solution that isn't terrible" to replace their aging implementation.

I've been using Lemonstand V1 for a couple of years now, it's been really decent, though they're zoning it out to make way for V2. They're moving to a cloud hosted monthly cost, without a lot of core features from V1, which means my agency needs to find an alternative. Obviously the one that stands out is Magento, but I've logged in and clicked around and looks so bad. [...] I have recently found "builtwith.com" which seems to show usage stats for different ecommerce systems, though I cannot seem to find anything very good on that list which looks reliable. The most promising thing I could find was called "Sylius" (http://sylius.org/) which looks fantastic, BUT, it's newish, and there are no docs, it's not being supported by a company, it's only being held up by the community. Can anyone suggest any other alternatives to look into?

The comments to the post range from suggestions of other solutions to attempts to reinforce ones already mentioned:

  • "I'd go with the biggest names in eCommerce for PHP. That will give you the most leverage. We run our own ecommerce software and when your missing a community, features, and market share, it will be a ruff battle selling customers on your solution who are aware of software like Magento."
  • "No, sorry. No joke. Every ecommerce solution I touched is terrible. And Magento is hell."
  • "Drupal with the Ubercart module is pretty nice."
  • "You have checked out OpenCart, haven't you?"
  • "WooCommerce has been pretty good if you're on WordPress. Actually similar to Magento."
  • "In my experience none stand above the rest and all have their drawbacks, especially when you just need to getting something slightly custom up and running. We most recently used CS Cart and it was not terrible."

Check out the post for more feedback and suggestions.

IT World:
Does relying on an IDE for development make you a bad programmer?
February 27, 2014 @ 10:04:45

On the IT World site there's an interesting post that poses the question - does relying too heavily on your IDE make you a bad programmer?

The truth is that a good IDE makes you vastly more productive than a bad one or none at all. Projects are off the ground faster thanks to helpful scaffolding. Coding moves faster thanks to intelligent autocompletes and IDE refactoring tools. Integrated unit testing helps your application be more maintainable. Built in deployment tools, web servers, code analysis, and compile time bundling streamlines the workflow. It also standardizes the developer experience which benefits both the programmer and the business.

He mentions the original post that got him thinking about the topic. It talks about the reliance one developer feels like they now have on their IDE. They feel that it's "made them lazy" in their development practices. The article isn't specifically focused around PHP as there are IDEs for other languages that do a lot more for work for you. There are some in the PHP world, like PHPStorm that do rank up there as far as automated features, though.
