It is not very nice to use native php resources like $_GET as Laravel gives us easy ways to get the variables. As a matter of standard, whenever possible use the resources of the laravel itself instead of pure PHP.

There is at least two modes to get variables by GET in Laravel ( Laravel 5.x or greater):

Mode 1

Route:

Route::get('computers={id}', 'ComputersController@index');

Request (POSTMAN or client...):

http://localhost/api/computers=500

Controler - You can access the {id} paramter in the Controlller by:

public function index(Request $request, $id){
   return $id;
}

Mode 2

Route:

Route::get('computers', 'ComputersController@index');

Request (POSTMAN or client...):

http://localhost/api/computers?id=500

Controler - You can access the ?id paramter in the Controlller by:

public function index(Request $request){
   return $request->input('id');
}

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      See also  http   laravel com docs input input

This is the best practice  This way you will get the variables from  GET method as well as POST method      public function index Request  request                 data  request- gt all                dd  data           OR if you want few of them then     public function index Request  request                 data  request- gt only  id   name   etc                dd  data           OR if you want all except few then     public function index Request  request                 data  request- gt except    token                dd  data

We have similar situation right now and as of this answer  I am using laravel 5 6 release   I will not use your example in the question but mine  because it s related though   I have route like this   Route  name  your name here  - gt get   your uri    YourController someMethod      Then in your controller method  make sure you include   use Illuminate Http Request    and this should be above your controller  most likely a default  if generated using php artisan  now to get variable from the url it should look like this     public function someMethod Request  request           foo    request- gt input  start         bar    request- gt input  limit            some codes here       Regardless of the HTTP verb  the input   method may be used to retrieve user input   https   laravel com docs 5 6 requests retrieving-input  Hope this help

I haven t tested on other Laravel versions but on 5 3-5 8 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- gt page           or in your controller public function foo Request  request    dd  request- gt 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- gt 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- gt 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- gt query  page       with a default  page    request- gt 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
