How to use -> and =>

I have seen these 2 codes a lot in php files. What's the difference?

'href'      => $this->url->link('common/home'),

if (isset($this->request->get['path'])) 


$data = array(
                'filter_category_id' => $category_id,
                'filter_filter'      => $filter, 
                'sort'               => $sort,
                'order'              => $order,
                'start'              => ($page - 1) * $limit,
                'limit'              => $limit
            );

The -> is used to access properties and methods that are part of an Object in PHP.

In your example the $this variable is an object which contains the objects url and request.

The url object contains a function (considered a method when within an object) of link. The request object contains a variable (considered a property when within an object) of get which just so happens to be associative array which contains the variable 'path'.

The => is as far as I know only used to identify a key to a value in an associative array as shown in your example.

Hope that helps?
