PHP Final Class

In PHP 5 a new mechanism added in OOPS which is Final Keyword.

If a class declares by final keyword then the class never extended. Child class can’t be created of any Final class.

It is restrict the overriding a method.

Only class and function may be declared as Final but no variable or properties cannot declare as Final.

Example

sayHello();
?>

Output:

Fatal error: Class Sons may not inherit from final class (Brahmachari)
