which languages is this normal too..
if you refer to java, that uses the 'super' function, you need only
explicitly call super if your constructor has arguments, otherwise an
implicit call is made to the parents defualt constructor ( one with
arguments).
c++ also will call the parent defualt constructor automatically as well
i beleive.
that aside, i do release my mistake in the workaround, ive noted the
use of parent::__construct().
im not really concerned with coding, i was more simply interested in why
it was done this way, in such a way, that a child class can be
inherited with parent class construction.

Hi, is there a reason that when a child class is instantiated the parent

The obvious workaournd for this is to simply call
$this->parentConstructor(); in the child class constructor, however,
this seems strange..parent::__construct(), to be exact :)
Am i way off base here...?
Thanks
JasonMost languages i know do that ("forcing" you to call super or alike).
The only small "annoyance" i see is that parent::__construct() doesn't
automatically use the parameters that were passed to the constructor,
but i think one can live with that.Stefan
Hello Jason,
maybe this time we neither had c++ nor java in mind, this time it was
delphi.
