In Laravel 5   to set a variable just once and access it  globally   I find it easiest to just add it as an attribute to the Request    request- gt attributes- gt add   myVar    gt   myVar      Then you can access it from any of your controllers using    myVar    request- gt get  myVar      and from any of your blades using      Request  get  myVar

Okay  I m going to completely ignore the ridiculous amount of over engineering and assumptions that the other answers are rife with  and go with the simple option   If you re okay for there to be a single database call during each request  then the method is simple  alarmingly so   class BaseController extends  Controller        protected  site settings       public function   construct                     Fetch the Site Settings object          this- gt site settings   Setting  all            View  share  site settings    this- gt site settings              Now providing that all of your controllers extend this BaseController  they can just do  this- gt site settings   If you wish to limit the amount of queries across multiple requests  you could use a caching solution as previously provided  but based on your question  the simple answer is a class property

In Laravel  5  you can create a file in the config folder and create variables in that and use that across the app  For instance  I want to store some information based on the site  I create a file called site vars php  which looks like this  lt  php return        supportEmail    gt   email gmail com        adminEmail    gt   admin sitename com      Now in the routes  controller  views you can access it using Config  get  site vars supportEmail    In the views if I this    Config  get  site vars supportEmail       It will give email gmail com Hope this helps  EDiT- You can also define vars in  env file and use them here  That is the best way in my opinion as it gives you the flexibility to use values that you want on your local machine  So  you can do something this in the array  supportEmail    gt  env  SUPPORT EMAIL    defaultmail gmail com    Important - After you do this  don t forget to do php artisan config cache  In case  there s still some problem  then you can do this  usually it would never happen but still if it ever happens  php artisan cache clear php artisan config cache

You can also use Laravel helper which I m using  Just create Helpers folder under App folder then add the following code   namespace App Helpers  Use SettingModel  class SiteHelper       public static function settings                 if null     session  settings                settings   session  settings             else             settings   SettingModel  all              session   settings    gt   settings                      return  settings            then add it on you config   app php under alliases   aliases    gt          Site    gt  App Helpers SiteHelper  class      1  To Use in Controller  use Site  class SettingsController extends Controller       public function index                  settings   Site  settings            return  settings            2  To Use in View    Site  settings

There are two options    Create a php class file inside app libraries YourClassFile php  a  Any function you create in it would be easily accessible in all the views and controllers    b  If it is a static function you can easily access it by the class name   c  Make sure you inclued  app libraries  in autoload classmap in composer file  In app config app php create a variable and you can reference the same using  Config  get  variable name      Hope this helps   Edit 1   Example for my 1st point      app libraries DefaultFunctions php  class DefaultFunctions       public static function getSomeValue            Fetch the Site Settings object       site settings   Setting  all         return  site settings              composer json   autoload              classmap                         app libraries     add the libraries to access globaly                      YourController php      default functions    new DefaultFunctions         default functions- gt getSomeValue

If you are worried about repeated database access  make sure that you have some kind of caching built into your method so that database calls are only made once per page request   Something like  simplified example    class Settings        static protected  all       static public function cachedAll             if  empty self   all                self   all   self  all                      return self   all            Then you would access Settings  cachedAll   instead of all   and this would only make one database call per page request  Subsequent calls will use the already-retrieved contents cached in the class variable   The above example is super simple  and uses an in-memory cache so it only lasts for the single request   If you wanted to  you could use Laravel s caching  using Redis or Memcached  to persist your settings across multiple requests   You can read more about the very simple caching options here   http   laravel com docs cache  For example you could add a method to your Settings model that looks like   static public function getSettings          settings   Cache  remember  settings   60  function             return Settings  all                return  settings      This would only make a database call every 60 minutes otherwise it would return the cached value whenever you call Settings  getSettings

I see  that this is still needed for 5 4  and I just had the same problem  but none of the answers were clean enough  so I tried to accomplish the availability with ServiceProviders  Here is what i did    Created the Provider SettingsServiceProvider        php artisan make provider SettingsServiceProvider    Created the Model i needed  GlobalSettings         php artisan make model GlobalSettings    Edited the generated register method in  App Providers SettingsServiceProvider  As you can see  I retrieve my settings using the eloquent model for it with Setting  all             public function register                  this- app- singleton  App GlobalSettings   function   app                return new GlobalSettings Setting  all                            Defined some useful parameters and methods  including the constructor with the needed Collection parameter  in GlobalSettings          class GlobalSettings extends Model               protected  settings          protected  keyValuePair           public function   construct Collection  settings                         this- settings    settings              foreach   settings as  setting                    this- keyValuePair  setting- key     setting- value                                   public function has string  key      check key exists              public function contains string  key      check value exists              public function get string  key      get by key                 At last I registered the provider in config app php           providers                                 App Providers SettingsServiceProvider  class            After clearing the config cache with php artisan config cache you can use your singleton as follows            foo   app App GlobalSettings  class       echo  foo- has  company      foo- get  company      Stack Exchange Inc        You can read more about service containers and service providers in Laravel Docs   Service Container and Laravel Docs   Service Providers   This is my first answer and I had not much time to write it down  so the formatting ist a bit spacey  but I hope you get everything     I forgot to include the boot method of SettingsServiceProvider  to make the settings variable global available in views  so here you go          public function boot GlobalSettings  settinsInstance                View  share  globalsettings    settinsInstance             Before the boot methods are called all providers have been registered  so we can just use our GlobalSettings instance as parameter  so it can be injected by Laravel   In blade template              globalsettings- get  company

At first  a config file is appropriate for this kind of things but you may also use another approach  which is as given below  Laravel - 4       You can keep this in your filters php file App  before function  request        App  singleton  site settings   function            return Setting  all                    If you use this line of code then it ll be available in any view        as  site settings but you may also use app  site settings   as well     View  share  site settings   app  site settings           To get the same data in any controller you may use    site settings   app  site settings      There are many ways  just use one or another  which one you prefer but I m using the Container

I have found a better way which works on Laravel 5 5 and makes variables accessible by views  And you can retrieve data from the database  do your logic by importing your Model just as you would in your controller   The     means you are referencing all views  if you research more you can choose views to affect   add in your app Providers AppServiceProvider php   lt  php      namespace App Providers       use Illuminate Contracts View View       use Illuminate Support ServiceProvider      use App Setting   class AppServiceProvider extends ServiceProvider                  Bootstrap any application services                 return void            public function boot                    Fetch the Site Settings object         view  - gt composer      function View  view                 site settings   Setting  all                 view- gt with  site settings    site settings                                     Register any application services                 return void             public function register
