In Laravel, you can use global variables by defining them in the config/app.php file or by using the env() helper function.

  1. Defining global variables in config/app.php: You can define global variables in the config/app.php file under the "global_variables" array. These variables will be accessible throughout your application. Here's an example of how you can define a global variable in the config/app.php file:
1
2
3
4
5
6
return [
    'global_variables' => [
        'app_name' => 'My Laravel App',
        'version' => '1.0',
    ],
];


You can then access these variables in your application by using the config() helper function:

1
$configValue = config('app.global_variables.app_name');


  1. Using the env() helper function: You can also define global variables in the .env file in the root directory of your Laravel application. These variables can be accessed using the env() helper function. Here's an example of how you can define a global variable in the .env file:
1
2
APP_NAME=My Laravel App
APP_VERSION=1.0


You can then access these variables in your application by using the env() helper function:

1
2
$appName = env('APP_NAME');
$version = env('APP_VERSION');


By using global variables in Laravel, you can easily access and use common data throughout your application without having to redefine the variables in multiple locations.
