What is a final class?A final class is a class that can't be extended. Also methods could be declared as final to indicate that cannot be overridden by subclasses. Preventing the class from being subclassed could be particularly useful if you write APIs or libraries and want to avoid being extended to alter base behaviour.
How do you call a final class method in PHP?The final keyword prevents child classes from overriding a method or constant by prefixing the definition with final . If the class itself is being defined final then it cannot be extended. Note: Properties cannot be declared final: only classes, methods, and constants (as of PHP 8.1. 0) may be declared as final.
What is the use of final class?The main purpose of using a class being declared as final is to prevent the class from being subclassed.
