Getting GET "?" variable in laravel

On 5.3-8.0 you reference the query parameter as if it were a member of the Request class.

1. Url

http://example.com/path?page=2

2. In a route callback or controller action using magic method Request::__get()

Route::get('/path', function(Request $request){
 dd($request->page);
}); 

//or in your controller
public function foo(Request $request){
 dd($request->page);
}

//NOTE: If you are wondering where the request instance is coming from, Laravel automatically injects the request instance from the IOC container
//output
"2"

###3. Default values We can also pass in a default value which is returned if a parameter doesn't exist. It's much cleaner than a ternary expression that you'd normally use with the request globals

   //wrong way to do it in Laravel
   $page = isset($_POST['page']) ? $_POST['page'] : 1; 
   
   //do this instead
   $request->get('page', 1);
  
   //returns page 1 if there is no page
   //NOTE: This behaves like $_REQUEST array. It looks in both the
   //request body and the query string
   $request->input('page', 1);

###4. Using request function

$page = request('page', 1);
//returns page 1 if there is no page parameter in the query  string
//it is the equivalent of
$page = 1; 
if(!empty($_GET['page'])
   $page = $_GET['page'];

The default parameter is optional therefore one can omit it

###5. Using Request::query()

While the input method retrieves values from entire request payload (including the query string), the query method will only retrieve values from the query string

//this is the equivalent of retrieving the parameter
//from the $_GET global array
$page = $request->query('page');

//with a default
$page = $request->query('page', 1);
 

###6. Using the Request facade

$page = Request::get('page');

//with a default value
$page = Request::get('page', 1);

You can read more in the official documentation https://laravel.com/docs/5.8/requests

Take a look at the $_GET and $_REQUEST superglobals. Something like the following would work for your example:

$start = $_GET['start'];
$limit = $_GET['limit'];

EDIT

According to this post in the laravel forums, you need to use Input::get(), e.g.,

$start = Input::get('start');
$limit = Input::get('limit');
