PHP Classes / Objects Question using $this

[socalnate]

I've been attempting to understand classes and objects.  There is one bit of information I'm confused on and that is when you can use $this. 

 

From what I've read I'm assuming you can ONLY use $this to reference variables within the CLASS (brackets) only.  You cannot create an object and then try to call (or echo) a variable within that class using $this.  EX:

 

<?php

$myobject = new foo_object();

echo $this->foo ;

?>

 

Correct way is this:

 

<?php

$myobject = new foo_object();

echo $myobject->foo

?>

 

I am right?

Correct! $this-> can only be used within the class definition.

 

This should be in the OOP section btw.
