PHP: Undefined variable

Question

I have the code below. For some reason when I run this code it say the variable rsLinks is undefined. Yet clearly you can see that it is defined in the constructor. Can you tell me what I am doing wrong?

 require_once "..\Models\Links.php";

class Navigator
{
    public $rsLinks;

    public function __construct() 
    { 
        $rsLinks = new rsLinks();
    }

    public function getLinks()
    {
        $links = $rsLinks;
    }
}

$navigator = new Navigator();
$navigator->getLinks();

I expect this has something to do with scoping.

Use $this->rsLinks; instead.

Oh thank you. Now I feel dumb. Thanks Odinn so quickly as well!

I personally hate the fact that you have to use $this in PHP... :) you welcome.

public function getLinks()
{
    //$links = $rsLinks;
    $links = $this->rsLinks;
}

$rsLinks is a regular local variable with function scope.
To access object properties, use $this->rsLinks.

Php is not Java. You need to use $this.

$this->rsLink

On both cases.
