need help understanding this

[dan_t]

I got this error:

Fatal error: Using $this when not in object context

 

What makes the $this work?

 

where exactly should the $this be used, for that matter why is it used.

I thought it was just a short cut for the current page your on, but now I'm not sure.

What makes the $this work?

 

Being in an object context?

 

Example:

class test {
     public $item;
     public function echoItem() {
          echo $this->item;
     }
}

$cl = new test();
$cl->item = "blah";
$cl->echoItem();
