access parent method php4

[RR]

I have two classes:

class Base
{
function Insert()
{
// does stuff
}
}

class Derived extends Base
{
function Insert()
{
// does some different stuff
parent::Insert( ); // then calls base class
}
}

Now, in main line code I want to do this:

$der = new Derived();

$der->parent::Insert (); // I want to call the base class's Insert
method - doesn't work

$der->Base::Insert() ; // this doesn't work either

Is it possible to access a hidden parent class method with a child class
object in PHP4?

thanks,
RR

When you extend a class you override any methods from the parent
class that have the same name. But if you just call $der->insert()
then it should work as long as Derived::insert () includes the call
to it's parent method.

RR,

I guess you need to write an aditional method:

class Derived extends Base
{
function Insert()
{
// does some different stuff
parent::Insert( ); // then calls method from base class
}

functon baseInsert()
{
parent::Insert( );
}
}
then call $der->basInsert();

Alternativily you could rename the Direved::Insert () method:
class Derived extends Base
{
function extendedInsert( )
{
// does some different stuff
$this->Insert(); // then calls inherited method
}
}

These two solutions will give different polymorphisms for Insert(). I
mean, if you can have arrays like:

$polymorhicArra y = array( new Base(), new Derived(), new Base() );

and you would want to do:

forEach ($polymorhicArr ay as $baseOrDerived)
$baseOrDerived->Insert();

Then i guess only one of the above solutions will do what you want.

Thanks. That's what I did....just hoping for a better (more direct)
solution.
