if anyone can, would you please explain why the below code does what it
does? I would expect $this->test in TestInstance to refer to the
inherited $test from Test. Using php5RC3. Thanks.
<?php
abstract class Test {
private $test;
abstract public function addToTest($i);
}
class TestInstance extends Test {
public function __construct() {
$this->test = 0;
}
...
The variable is private for Test, so TestInstance does not have access
to it. By assigning 0 to $this->test in the constructor of TestInstance,
you create a new property of TestInstance that is public (the default).
var_dump() shows it clearly:
object(TestInstance)#1 (2) {
["test:private"]=> NULL <---- belongs to Test
["test"]=> int(3) <---- belongs to TestInstance
}
I think one could argue that that test:private shouldn't even be
there. To me that test:private would imply that is TestIntance's
private variable.
Right, ["Test::test:private"] would be better
