We know the .env method in which we define constants in the .env file but other than that is there any method like storing all constants in a constant file?. Lets see. If you are using a lot of constants and most of them are used globally in the application storing the constants in a constant.php file is a simple and good option. For this method just create a file say constants.php in the config directory. In the file you have to return array of config values.

return [
    'options' => [
       
'option_attachment' => '13',
        'option_email'
=> '14',
       
'option_monetery' => '15',
       
'option_ratings' => '16',
       
'option_textarea' => '17',
    ]
];

Access  these constants as shown below.

Config::get('constants.options');
// or if you want a specific one
Config::get('constants.options.option_attachment');
