I am working on my first ever Laravel 4 REST project. My basic question is how can I create a global variable that will hold the value to be used in my controller methods? Here are the requirements for it... There needs to be 2 variables ($token - string and $expirationdate - date). I need for all calls to the controller methods for all clients to reference a singleton value (just meaning one value for everyone not that it has to be stored as a singleton). The token is going to be a randomly generated string. However for each call to the method I will need to check the variable for the expiration date. If it has expired then I need to be able to update the $token variable with a newly generated random string and then modify the expiration date to be something like todays date + 30 days.

So what I am thinking is there a way for the variable to be stored in memory on the server that can be accessed in a thread safe manner. Or will this require that I store the value in some sort of settings file which I can read and write to also in a thread safe manner.

I tried adding the following line in the app.php... 'securitytoken' => 'defaultvalue',

Then I could use the following line of code to access the value in my controller $token = Config::get('app.securitytoken');

However if the token expires I tried adding this line to "update" the value of the setting. Config::set('app.securitytoken', Str::random(32));

Then no matter what every call to the controller always gets the 'defaultvalue' returned.

Also I am expecting around 1 million hits per day so that is why I prefer to just save value in memory if needed.

Any help would be greatly appreciated. Thanks Wayne
