You can do the following:
class derived extends base {
function __construct() {
parent::__construct();
echo "derived::__construct()\n";
}
I know know.
What I want to know is why the base::__construct() is called (in
automatic) only when derived::__constuct() is missing.
I think that or the base::__construct() is always in automatic called or
it is never called (always in automatic).
In ZE2 each class has a constructor. That constructor can be overwritten
by writing a method named "__construct". So far so good. Unlike other
languages, C++ for one, PHP does not call any inherited constructors
automatically, C++ calls the default constructor if not set explicitly. But
PHP inherits the constructor if it is not redeclared/overwritten. Therfor
if the base has a constructor and the derived has not the inherited (the
one from base) is called.
