Create a helpers.php file in your app folder and load it up with composer:

​

"autoload": {

    "classmap": [

        ...

    ],

    "psr-4": {

        "App\\": "app/"

    },

    "files": [

        "app/helpers.php" // <---- ADD THIS

    ]

},

​

After adding that to your composer.json file, run the following command:

​

composer dump-autoload

​

"autoload": {

    "files": [

        "app/helpers.php"

    ],

    "classmap": [

        "database/seeds",

        "database/factories"

    ],

    "psr-4": {

        "App\\": "app/"

    }

},

​

First create the required function inside the app directory within a .php file as

​

helpers.php

​

if (!function_exists('getServices')) {

    public function getServices() {

        return DB::table('services')->get();

    }

}

and include this file in composer.json inside autoload/files array as

​

composer.json

​

"autoload": {

    "classmap": [

        "database"

    ],

    "psr-4": {

        "App\\": "app/"

    },

    "files": [

        "app/helpers.php"

    ]

},

Then update the composer, now you can able to directly use the created function inside your whole project as the file is automatically loaded when application get bootstraped

​

$result = getServices();

use Illuminate\Support\Arr;

$array = Arr::add(['name' => 'Desk'], 'price', 100);

// ['name' => 'Desk', 'price' => 100]

$array = Arr::add(['name' => 'Desk', 'price' => null], 'price', 100);

// ['name' => 'Desk', 'price' => 100]

$callback = function ($value) {

    return (is_numeric($value)) ? $value * 2 : 0;

};

​

$result = with(5, $callback);

​

// 10

​

$result = with(null, $callback);

​

// 0

​

$result = with(5, null);

​

// 5
