It's used to access things in a class
example:
[code]
class class_name
{
$number=5;
$foo=6;
$bar="hello";

function bar()
{
echo $this->number;
echo $this->foo;
echo $this->bar;
}
}

$thingy=new class_name;

echo $thingy->number; // will output 5
echo $thingy->foo; //will output 6
echo $thingy->bar; //will output 'hello'

$thingy->bar(); will output the same thing as above
[/code]

i think a mod or something should make a sticky thread because this question has been asked a lot lately.
