Summary
The PHP-FIG group addresses a wide range of things through its PSRs. Some of them focus on the structure and readability of the code, others strive for increased interoperability by defining numerous interfaces. These PSRs, directly or indirectly, contribute to improved quality of our project and the third-party libraries we might use. The RFC 2119 standard was a common base for each of the PSR. It removes any ambiguity around may, must, should, and similar words that describe the standard. This ensures that the documentation gets read just as PHP-FIG intended it. While we might not be in touch with each of the standards on a day-to-day basis, it is worth paying attention to them when choosing the libraries for our project. Standard compliant libraries, such as Monolog, usually mean more flexibility, as we can easily switch between different libraries in later stages of the project.
Moving forward, we will look into configuration options, mechanisms, and libraries behind error handling...
