laravel sets global array

Laravel is a popular development framework that provides many powerful features, one of which is setting a global array. Global arrays can be used throughout your application, allowing you to store and access data that needs to be used in multiple places.

This article will introduce how to set up a global array and use it in a Laravel application.

1. Using config files

The config folder in Laravel contains all the configuration files needed in the application. You can use the files in the config folder to set the global array.

First, you need to create a new configuration file, name it "globals.php" and place it in the config folder. Next, you can add the array to the file using the following code:

return [
    'global_array' => [
        'item_1' => 'value_1',
        'item_2' => 'value_2',
    ],
];

Now you can use the array throughout your application. To access it, use the following code:

$config = config('globals.global_array');

$item1 = $config['item_1'];
$item2 = $config['item_2'];

2. Using a service provider

You can also use a service provider to set a global array. Service providers are responsible for instantiating and registering various services, classes, and components in the application.

First, you need to create a new service provider. It can be easily created using the Artisan command line tool:

php artisan make:provider GlobalArrayServiceProvider

Then you need to set the array in the boot method of that service provider:

public function boot() {
    $GLOBALS['global_array'] = [
        'item_1' => 'value_1',
        'item_2' => 'value_2',
    ];
}

This will create a global across the entire application variable, you can use it anywhere. To access it, use the following code:

$globalArray = $GLOBALS['global_array'];

$item1 = $globalArray['item_1'];
$item2 = $globalArray['item_2'];

NOTE: While it is possible to set global variables using a service provider, it is best avoided as it may have unpredictable consequences.

Summary

Setting a global array in a Laravel application is a very simple and practical feature. You can set it using a config file or a service provider and use it anywhere in your application. No matter which method you use, consider the impact of ongoing maintenance.
