1.2.15. Abstract Or Implements¶
A class must implements all abstract methods of it parents, or be abstract too.
PHP detect such error when all classes are loaded: in a code source where classes are split by files, such error it won’t be detected until execution, where PHP stops with a Fatal Error : Class BA contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (A\:\:aFoo).
<?php
abstract class Foo {
abstract function FooBar();
}
// This is in another file : php -l would detect it right away
class FooFoo extends Foo {
// The method is not defined.
// The class must be abstract, just like Foo
}
?>
See also Class Abstraction.
