laravel helper function custom

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

laravel artisan helper function

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