Laravel Helper Functions Cheat Sheet

Helper is a Laravel utility class that offers a collection of powerful functions to accelerate backend development, reducing repetitive code and improving productivity.

Array & Object

Arr::add(['name' => 'Desk'], 'price', 100); // => ['name' => 'Desk', 'price' => 100]
Arr::collapse([[1, 2, 3], [4, 5, 6]]); // => [1, 2, 3, 4, 5, 6]
Arr::divide(['key1' => 'val1', 'key2' => 'val2']); // => [['key1','key2'],['val1','val2']]
Arr::dot($array);
Arr::except($array, ['key']);
Arr::first($array, function ($key, $value) {}, $default);
Arr::flatten(['name' => 'Joe', 'languages' => ['PHP', 'Ruby']]);
Arr::forget($array, 'foo');
Arr::forget($array, 'foo.bar');
Arr::get($array, 'foo', 'default');
Arr::has($array, 'products.desk');
Arr::only($array, ['key']);
Arr::pluck($array, 'key');
Arr::pull($array, 'key');
Arr::set($array, 'key', 'value');
Arr::set($array, 'key.subkey', 'value');
Arr::sort($array, function () {});
Arr::sortRecursive();
Arr::where();
Arr::shuffle($array, 'I-AM-GROOT');
Arr::wrap($array);
head($array);
last($array);

Path Helpers

app_path(); // full path to the app directory
base_path(); // full path to the project root
config_path(); // full path to the config directory
database_path(); // full path to the database directory
elixir(); // path to versioned Elixir file
public_path(); // full path to the public directory
storage_path(); // full path to the storage directory

String Helpers

Str::camel($value); // convert to camelCase
class_basename($class); // class name without namespace
e('
'); // htmlentities
Str::startsWith('Foo bar.', 'Foo');
Str::endsWith('Foo bar.', 'bar');
Str::snake('fooBar'); // => foo_bar
Str::studly('foo_bar'); // => FooBar
trans('foo.bar'); // translate using localization files
trans_choice('foo.bar', $count); // pluralization

URLs and Links

action('FooController@method', $parameters);
asset('img/photo.jpg', $title, $attributes); // HTTP/HTTPS aware
secure_asset('img/photo.jpg', $title, $attributes);
route($route, $parameters, $absolute = true);
url('path', $parameters = [], $secure = null);

Other Helpers

auth()->user(); // get authenticated user
back(); // redirect to previous location
bcrypt('my-secret-password'); // hash a password
collect(['taylor', 'abigail']); // create a collection
config('app.timezone', $default); // get config value
{!! csrf_field() !!} // CSRF hidden input
@csrf // Blade directive for CSRF
$token = csrf_token(); // get CSRF token
dd($value); // dump and die
dump($value); // dump variable
$env = env('APP_ENV'); // get environment variable
event(new UserRegistered($user)); // fire event
$user = factory(App\User::class)->make(); // model factory
{!! method_field('delete') !!} // spoof HTTP verb
@method('delete')
$value = old('value'); // retrieve old input
return redirect('/home'); // redirect response
$value = request('key', $default = null); // get request input
return response('Hello World', 200, $headers); // create response
$value = session('key'); // get session value
session()->put('key', $value); // store in session
value(function () { return 'bar'; }); // resolve value
return view('auth.login'); // render view
$value = with(new Foo)->work();

By using these helpers, developers can write cleaner, more expressive code and focus on business logic rather than low‑level implementation details.
