Introduction to PHP 8 Best Practices

Mastering PHP 8 best practices

In this chapter, we will be introduced to the best practices that are currently enforced in PHP 8. We will cover several significant method signature changes and how their new usage continues the general PHP trend of helping us produce better code. We will also have a look at how private methods, interfaces, traits, and anonymous class usage have changed. Finally, we will discuss important changes in how namespaces are parsed.

Mastering the best practices that will be covered in this chapter will not only move us toward writing better code but also teach us how to avoid the potential code breaks that might arise if we fail to grasp these new practices. In addition, the techniques discussed in this chapter will help us write code that’s more efficient than was possible in the past.
