Are there any potential pitfalls or drawbacks to using the "final" keyword in PHP classes?
Using the "final" keyword in PHP classes can restrict the ability to extend or override certain methods or properties in child classes. This can limit the flexibility and modifiability of the codebase. To solve this, carefully consider when and where to use the "final" keyword to ensure it aligns with the design and requirements of the project.
class ParentClass {
final public function finalMethod() {
// This method cannot be overridden in child classes
}
}
class ChildClass extends ParentClass {
// This will cause a fatal error
public function finalMethod() {
// Attempting to override a final method will result in a fatal error
}
}
