I've found an inconsistency with: Example #2 Abstract class example
If you remove the default value of $separator
<?php
public function prefixName($name, $separator) {
}
?>
Then php will show this fatal message:
Fatal error: Declaration of ConcreteClass::prefixName() must be compatible with AbstractClass::prefixName($name) in /index.php on line 23
Stange enough it gives an incorrect declaration of "ConcreteClass::prefixName()"... It is missing both arguments. Because of that I'm assuming that this is just a bug that maybe already has been taking care of in newer versions. (Or is just specific to my version) I'm mainly noting this because it was driving me absolutely insane in some test code that I was writing derived from Example #2 (without a default value for an extra argument). Perhaps this saves some frustrations to other people.
