[SOLVED] Parent variables

[coldkill]

Hello all.

 

I'm building a new website for myself (well it's a CMS so I can basically re-use it for other projects as well). It uses classes and extended classes but I have one problem. I can't access variables from the parent class. It seems that the parent:: scope resolution operator with variables only works with PHP5 and later. My server currently runs PHP4 so it doesn't work.

 

Anyone know how to access variables from a parent class in PHP4? I tried using functions as well and that didn't work. IE:

<?php 
class b extends a
{
     function b()
     {
          echo parent::aFunction();
     }
}
?>

 

Thanks in advance.

<?php 
class b extends a
{
     function b()
     {
          echo a::aFunction();
     }
}
?>

hmmm as far as i'm aware (or can remember from using php 4), parent works fine in php 4.

 

parent::method() = used to call a function that exists in parent class but has been overwritten by descendent

$this->method() = call a method that has been defined in either descendent class or parent

$this->variable = used to access a variable that has either been set in parent class or overwritten by descendent

you mention variables, but your example would imply a method call - which one is it you're trying to do, and what result are you getting?

to piggyback off of thorpe's answer.

 

<?php

class b extends a

{

    function b()

    {

          echo $this->aFunction();

    }

}

?>

The function works fine. I'm trying to get a variable from a parent function (one defined with the var constructor).

 

The only way I can think of how to do this is use a function and return the value of the variable, but that didn't work when I tested it...

 

Thanks,

parent class* not parent function.

[corbin]

class Class1 {
	var $a = 'foo';

	function Class1() {
		return $this->a;
	}

}

class Class2 extends Class1 {

	function Class2() {
		echo $this->a;
		echo $this->Class1();
	}

}

$c = new Class2();
//returns 'foofoo';

 

Does that not work?  I know it works in PHP 5...

 

Or is there a reason you're specifically trying to use the parent:: syntax?

I think it's because I'm running PHP4. I will try that though. Thanks.
