Summary: Mastering PHP 8 Best Practices

Key takeaways

• PHP 8, as we learned, is much stricter in terms of how it defines magic methods.

• In this chapter, we learned about method signature changes and how to reduce potential bugs by using magic methods properly.

• We also learned about the method signature changes in both the Reflection and PDO extensions. With the knowledge we’ve gained in this chapter, we can avoid potential problems when migrating to PHP 8.

• In addition, we learned about changes in how static methods can be called, as well as a new static return type.

• Then, we learned how to make the best use of private methods, as well as how to exert greater control over anonymous classes.
