We use functions in our projects by importing and name spacing it in a class, which is only accessible in that class. In this blog we will see how to use a global function which can be used anywhere in the entire project. You can use a global function in any of the class, Controller or View as it requires. First you need to create a Helpers folder in your projects app directory. In that Helpers folder create a php file, lets call it your_helper_function.php. Now write your function inside the your_helper_function.php file.

function your_function($parameters){



    //function logic

} 

function your_another_function($parameters){



    //function logic

} 

Now, in-order to make this function accessible throughout the project add this file to Files key in the composer.json file.

"autoload":{
    ...
    "files":[
       "app/Helpers/your_helper_function.php"
    ]
    ...
}

Lastly run composer dump autoload command in you project directory.

composer dump-autoload
