functions in classes ??

[Anon]

When I have a class with a subclass , and calls a method within the subclass from the class, everything is working out ok. But if a call the same method twice in the same script a get a function redeclaration error, is there anyone who knows a workaround for this problem or should I do this another way? (new to oop )

class One {
var class2;
//constructor
function One() {
$this -> class2 = new Two;
}

function getTestVar() {
$retVal = $this -> class2 -> getVar();
}
}

class Two {
var tmpVar;

function getVar() {
function getData() {
$tmpVar = "test";
}
$data = getData();
return $data;
}

I´m not 100 % sure of the code above as I dont have it at this location I´m writing from , but you get the idea!

So if I call class One:s getTestVar method more then once in a script I get a redeclaration fault on function getData in the method getVar of Class Two..

Greatful for help

Your problem is in the definition of class Two, specifically:

class Two {
var tmpVar;

function getVar() {
function getData() {
$tmpVar = "test";
}
$data = getData();
return $data;
}
}

You are declaring a function within a function, never a good idea be it a method or regular function.

So calling $this->class2->getVar() defines the function which you can only do once.

class Two should look like this:

class Two {
var tmpVar;

function getVar() {
$data = getData();
return $data;
}

function getData() {
return "test";
}
}
