How and where to create your own function and how to access it?

Question

Laravel

Hello!
Can you please tell me if it is possible to create your own separate functions (without using a controller. For example, laravel-function dd() ) in Laravel? If so, how and where should they be created and how should they be accessed after that? An example of what I want to do: I want to create a function that will show whether the user is online or not. And call it where the output of users or a specific user occurs. If there is a better solution to this problem, please advise.

Answer 2

Create helpers.php file in app folder
In composer.json file add lines to autoload

"files": [
            "app/helpers.php"
        ]

To make it look like this:

"autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\\": "app/"
        },
        "files": [
            "app/helpers.php"
        ]
    },

You can create any functions in this file.
Also don't forget to run composer dump-autoload
