Never have figured this out...

When you deal with classes, or even a foreach loop, what does this do? ->

I've seen this several times and have no clue what it does, for example:

<?php
    $var->depth++;
    $var->state[$var->depth] = "channel";
    $var->tmptitle[$var->depth] = "";
?>

Sorry for such a newbie question.

$var->variable_name

means that the variable "variable_name" belongs to the object "$var"

$var->function_name()

means that the function "function_name" is a member function of the object "$var"

It appears that state and tmptitle are arrays, so does that mean depth is a function?

depth is just a variable inside the class.

functions have () after them.
Here is a simple class.

HalfaBee

<?
class test
{
var $depth;
var $state[];

function test() // values for new class
{
   $state[0]=1;
   $state[1]=20;
   $depth=0;
}

function  show()
{
    echo $this->state[$this->depth];
}
} //end class


$a = new test();
$a->show();

?>

<?php
$var->depth++;
$var->state[$var->depth] = "channel";
$var->tmptitle[$var->depth] = "";
?>

$var is the instance of the class
$depth is a class member, which is an integer in this case
$state and $tmptitle are members of the class which are arrays.

in this case $depth is being used to specify the key value of the array $state and $tmptile.

$depth is accessed as $var->depth ( no $sign before depth)

take a look at the documentation http://ca3.php.net/oop
hope this helps
