Testing Strategy With the Help of Static Analysis
Apr 30, 2018 @ 12:49:41

php[architect] magazine has shared another article from their April 2018 issue on their site. In this article Ondrej Mirtes covers the use of static analysis to help testing and inform you of type safety issues.

When developing an application, our aim as software developers is to make sure it does what it ought to do and to keep the number of defects as low as possible. [...] In this article, I’d like to introduce you to the concept of type safety and how it can improve the reliability and stability of your code. Once your code is more type-safe, and that fact is verified by automated tools, you can cherry-pick which parts of your application need extensive unit tests and where you can rely just on well-defined types.

He starts off by talking about types (strict and dynamic) in PHP and the current state of the typing system for variable values. He covers the role of good type hinting in method and function definitions and how it can help IDEs like PhpStorm locate issues. He also talks about how type hints can provide you feedback on the design of the application and some of the tools that can help you find issues.

He wraps up the article with some tips for making your code more strongly typed and a look at what kind of tests are needed to help ensure these types remain enforced.

Exakat Blog:
Get ready for PHP 7.2
Nov 20, 2017 @ 09:56:21

With the final release of PHP 7.2 coming on the horizon the Exakat blog wants to be sure you and your code are prepared for some of the changes. In this new post they share things to change and improvements to expect in this latest version of the PHP language.

PHP 7.2 is around the corner, and shall be out soon, thanks to the hard work of @RemiCollet), Sara Golemon (@saramg) and countless others that run tests and submit bug reports. PHP 7.2 is already RC6, and the documentation has even been updated : it is high time to get ready for PHP 7.2.

We have been hard at work, at @Exakat, to prepare the migration analysis. This is our take on this upcoming task.

He's broken the changes coming down into a few categories based on the actions required and what you can do to prepare: Know, Lint, Static (Analysis), Unit testing and Logging. A chart is then included showing each of the changes, which category they fall into and links to more information about them and what has been updated (or added).

Exakat.io Blog:
Automatically Enforcing Coding Reference For PHP
Nov 10, 2016 @ 09:42:07

On the Exakat.io blog there's a post continuing on from a "dos and donts" article about programmer practices. In this new post cover some of the rules in a bit more detail from the original article.

Last week, I ran into ‘PHP Dos and Don’ts aka Programmers I Don’t Like‘ on reddit’s PHP group. It features a list of 11 points that the author hates finding in PHP code. [...] The most interesting point is that coding references are used to asses code. They may very well be automated, thanks to static analysis. I thought it was a good challenge for Exakat.

The list covers several of the rules in the list, providing a brief explanation (and a bit of how it relates back to PHP) including:

  • Unnecessary casting
  • Extra bracket and braces
  • Lack of coding standard
  • Too many nested if statements

He ends the post with a bit of detail about how the Exakat service is checking for these "failures" in it's newer "RadwellCode" report. He even gives the scores of some of the more well-known and used PHP projects including the Zend Framework (v1.12), WordPress, Composer and even Exakat itself.
