Classes

[Sniper05]

Could somebody explain this to me, i kind of understand this but i dont really get it:

I keep seeing $this around, but i havent a clue where that is set

eg: $this->edible = $edible;

What does the -> mean ? I think its actually setting $this to edible, am i wrong ?

Why are classes used? Because if this:

$this->block_name = $block[block_name];

isnt it rather pointless? (in this case)

Im kind of going in circles here, trying to work it out.

What is like the main difference between functions and classes?

If you have read the PHP Manual, you would find that:
Instead, in order to be able to access it's own functions and variables from within a class, one can use the pseudo-variable $this which can be read as 'my own' or 'current object'. Thus, '$this->items[$artnr] += $num' can be read as 'add $num to the $artnr counter of my own items array' or 'add $num to the $artnr counter of the items array within the current object'.

You'll probably need to learn some object oriented programming - try Practical PHP Programming: Objects.

Thanks for your help

Just one more thing though, whats the advantage of using classes over lots of functions?
