No, I'm wanting to EXTEND the orginal class.
meaning, my THECHILD class efines new methods/properties, and I want it used
as if it was part of the orginal THEPARENT Class.
Me just being picky.

It doesn't work that way, exactly. The child class can define new
methods and properties, but you must make an instance of the child
class, which will include the methods/properties from the parent, and
the new ones you have written.
If I'm understanding you correctly, you could rename you parent class to
child, name the child class the same as your parent and have the old
class extend the new class you've written. You code should then work
the same, but have the new methods/properties available.

walter you want to do a declaration in the class that you want to use the
base class in ie
when you declare your child class
class Web_child extends WEB_parent
{
-- your new and extended code here
}

Re: [PHP] Q on Class and EXTEND
What I am trying to do is EXTEND the PEAR::Auth Class with new properties and methods. Ok. But I still want to use the original instantiation call... $myAuth = Auth(); Which is instantiating the parent class. From what I understand of your question, you are wanting to instantiate the parent which, in turn, somehow calls upon (or instantiats) the child simply because the child EXTENDS the parent? Is that correct? If so, I don't believe this type of functionality/feature exists in any language, much less PHP. Am I wrong?

class Web_child extends WEB_parent

and then ... to access the class methods and variables of the
parent, you do it through the child.
class THEPARENT
var $originalthis;
function THEPARENT(){
}
}
class THECHILD extends THEPARENT
var $this;
function THECHILD($that) {
$this-this = $that;
}
}
// outside the class
$clss = new THECHILD($thatvar);
$clss-originalthis = 'how about that';

(I was told I could not do that) You rename the PEAR::Auth class to something like Auth2. Then, you create your new class and call it Auth. The new Auth class will extend the old one. Then you include your new methods in the new class. Your old code will still continue to work. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
