OO properties scope in extend class?

screative

I am defining a property in a base class and extending it with a parent class. When I instantiate the parent class I can not read the property set in the base class. Am I missing something with scope of the property set in the base class?

<?php

class base {

static $header;

function __construct() {
	$this->header = true;
}

}

class parent extends base {

function __construct() {
	//do something
}

}

$template = new parent;

if($template->header) {
//this does not print
  print 'header is defined';
}

?>

Static variables are associated with the class, not with the object, so you would need to do something like:

<?php

class Base {

static $header;

function __construct() {
	self::$header = true; // static vars referenced by class::$varname
}

}

class Child extends Base {

function __construct() {
	self::$header = true; // need to set it to true if Base not instantiated
}

}

$template = new Child;

if(Child::$header) {  // could as easily use Base::$header, instead
//this does not print
  print 'header is defined';
}
?>

Couple of things...

The 'base' constructor isn't called when you create a new 'parent' class (which, by the way, is an invalid name for a class :p). If you want to have it called, then you'd have to add something like "base::__construct();" to the constructor inside the 'parent' class.
You're accessing a static variable as if it were a property. The two are not interchangeable.

EDIT: NogDog beat me to it. :p
