Regular expressions, or sometimes simply called regex, represent a powerful set of tools which allow developers to split strings, perform character substitutions, and extract text based on matched patterns. The patterns, used in regular expressions, are an actual language that describe combinations of type castings and values that match the text you want to split, substitute, or extract. Regular expressions are an enormously powerful tool for the developer who understands them.

In this issue: Xdebug, Freelancing, Parsing text, MySQL Generated Columns, Gitflow, PhpStorm, and more.

This month we practice working “close to the hardware.” We’ll see why this is becoming more important to today’s software developers. We’ll use the PHP bitwise operators to manipulate single-bit binary numbers. We’ll then take a more general look at ways to learn what we need to learn.

In this issue: State machines, workflows, parsing text, MySQL without SQL, Continuous Integration, self-hosted git, CakePHP, Password Authentication, Issue Tracking, Algorithms, and more.

If you have trouble making change for a dollar without a calculator, and don’t care, this article may not be for you. Otherwise, come along with me! We’ll be converting between numbering systems. We’ll create an algorithm for converting between decimal (integer) and hexadecimal numbers.

Using events and command buses, self-hosted git, design workflows, parsing text, a look at CakePHP, Composer security, and more

Writing clean code, managing technical debt, testing with Mockery, Toxic Tech, API specifications, and more.

One of the fantastic things about the PHP language is that we, the community, are constantly evolving it. If you take a look at PHP code from just a few years ago, it can appear alien compared to anything written in modern PHP today. In fact, I’ve often stated that PHP was, in fact, unique […]

By Ondrej Mirtes. 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.

In this Episode Our hosts, Eric van Johnson and John Congdon dive into Testing in Practice and the April 2018 issue of php magazine and interview Robert Basic, one of the contributors to Mockery. Oscar talks about the importance of training for employees and rants against image slideshows.
