RE: [PHP] Question regarding :: syntax
So am i to understand that i will have to do it in this manner?
class A {
var $b;
A() {
}
function getB() {
return $this-B;
}
function setB($b) {
$this-B = $b;
}
}
class B extends A {
B($b) {
parent::setB($b);
}
}
$B = new B();
echo $B-getB();
This means writing a get and set function for every property that belongs to
the parent. I understand this is how it is done in other languages but the
manual is misleading in this case. It explicity says Sometimes it is
useful to refer to functions and variables... This lead me to believe that
you could directly access VARIABLES as well as functions. I guess i was
wrong. Oh well, it just means more typing for me, which means more hours,
which means more $.

No no no... B extends A, and you have an instance of B. Just do this:
class A
{
var $b;
*snip*
}
class B
{
function B($b)
{
$this-b = $b;
}
}
That will work fine.

RE: [PHP] Question regarding :: syntax
This may be a dumb question but, how can you be sure that the $this- is
referring to the parent classes' property and not the current class. On
that note, does it really matter of which one it refers?

RE: [PHP] Question regarding :: syntax
That is exactly what I thought, I was just looking for some reassurance. I have been working with C# lately and the syntax for classes is a lot more explicit. I wanted to make sure I wasn't making a mistake on what PHP implcitly does.
