Arrays & Objects

Arr::accessible()

The Arr::accessible method determines if the given value is array accessible:

1use Illuminate\Support\Arr;
2use Illuminate\Support\Collection;
3 
4$isAccessible = Arr::accessible(['a' => 1, 'b' => 2]);
5 
6// true
7 
8$isAccessible = Arr::accessible(new Collection);
9 
10// true
11 
12$isAccessible = Arr::accessible('abc');
13 
14// false
15 
16$isAccessible = Arr::accessible(new stdClass);
17 
18// false
1use Illuminate\Support\Arr;

9 
10// ['Taylor', 'Abigail']
1use Illuminate\Support\Arr;
2 
3$array = [
4 ['developer' => ['id' => 1, 'name' => 'Taylor']],

7 'direction' => 'desc'
8 ]
9];
10 
11Arr::query($array);
12 
13// name=Taylor&order[column]=created_at&order[direction]=desc

3$array = [
4 ['name' => 'Desk'],
5 ['name' => 'Table'],
6 ['name' => 'Chair'],
7];
8 
9$sorted = array_values(Arr::sort($array, function ($value) {

11}));
12 
13/*
14 [
15 ['name' => 'Chair'],
16 ['name' => 'Desk'],
17 ['name' => 'Table'],
18 ]
19*/
1use Illuminate\Support\Arr;
2 
3$array = [
4 ['name' => 'Desk'],
5 ['name' => 'Table'],
6 ['name' => 'Chair'],
7];
8 
9$sorted = array_values(Arr::sort($array, function ($value) {

11}));
12 
13/*
14 [
15 ['name' => 'Chair'],
16 ['name' => 'Desk'],
17 ['name' => 'Table'],
18 ]
19*/

1use Illuminate\Support\Arr;
2 
3$array = [
4 ['Roman', 'Taylor', 'Li'],
5 ['PHP', 'Ruby', 'JavaScript'],
6 ['one' => 1, 'two' => 2, 'three' => 3],
7];
8 
9$sorted = Arr::sortRecursive($array);
10 
11/*
12 [
13 ['JavaScript', 'PHP', 'Ruby'],
14 ['one' => 1, 'three' => 3, 'two' => 2],
15 ['Li', 'Roman', 'Taylor'],
16 ]
17*/
1use Illuminate\Support\Arr;
2 
3$array = [
4 ['Roman', 'Taylor', 'Li'],
5 ['PHP', 'Ruby', 'JavaScript'],
6 ['one' => 1, 'two' => 2, 'three' => 3],
7];
8 
9$sorted = Arr::sortRecursive($array);

12 [
13 ['JavaScript', 'PHP', 'Ruby'],
14 ['one' => 1, 'three' => 3, 'two' => 2],
15 ['Li', 'Roman', 'Taylor'],
16 ]
17*/

Arr::toCssClasses()

The Arr::toCssClasses conditionally compiles a CSS class string. The method accepts an array of classes where the array key contains the class or classes you wish to add, while the value is a boolean expression. If the array element has a numeric key, it will always be included in the rendered class list:

1use Illuminate\Support\Arr;
2 
3$isActive = false;
4$hasError = true;
5 
6$array = ['p-4', 'font-bold' => $isActive, 'bg-red' => $hasError];
7 
8$classes = Arr::toCssClasses($array);
9 
10/*
11 'p-4 bg-red'
12*/
1use Illuminate\Support\Arr;
2 
3$isActive = false;
4$hasError = true;
5 
6$array = ['p-4', 'font-bold' => $isActive, 'bg-red' => $hasError];
7 
8$classes = Arr::toCssClasses($array);
9 
10/*
11 'p-4 bg-red'
12*/

This method powers Laravel's functionality allowing merging classes with a Blade component's attribute bag as well as the @class Blade directive.

Arr::undot()

1use Illuminate\Support\Arr;
2 
3$array = [
4 'user.name' => 'Kevin Malone',
5 'user.occupation' => 'Accountant',
6];
7 
8$array = Arr::undot($array);
9 
10// ['user' => ['name' => 'Kevin Malone', 'occupation' => 'Accountant']]

URLs

action()

The action function generates a URL for the given controller action:

1use App\Http\Controllers\HomeController;
2 
3$url = action([HomeController::class, 'index']);
1use App\Http\Controllers\HomeController;
2 
3$url = action([HomeController::class, 'index']);

If the method accepts route parameters, you may pass them as the second argument to the method:

1$url = action([UserController::class, 'profile'], ['id' => 1]);
1$url = action([UserController::class, 'profile'], ['id' => 1]);

asset()

The asset function generates a URL for an asset using the current scheme of the request (HTTP or HTTPS):

1$url = asset('img/photo.jpg');
1$url = asset('img/photo.jpg');

You can configure the asset URL host by setting the ASSET_URL variable in your .env file. This can be useful if you host your assets on an external service like Amazon S3 or another CDN:

1// ASSET_URL=http://example.com/assets
2 
3$url = asset('img/photo.jpg'); // http://example.com/assets/img/photo.jpg
1// ASSET_URL=http://example.com/assets
2 
3$url = asset('img/photo.jpg'); // http://example.com/assets/img/photo.jpg

route()

The route function generates a URL for a given named route:

1$url = route('route.name');
1$url = route('route.name');

If the route accepts parameters, you may pass them as the second argument to the function:

1$url = route('route.name', ['id' => 1]);
1$url = route('route.name', ['id' => 1]);

By default, the route function generates an absolute URL. If you wish to generate a relative URL, you may pass false as the third argument to the function:

1$url = route('route.name', ['id' => 1], false);
1$url = route('route.name', ['id' => 1], false);

secure_asset()

The secure_asset function generates a URL for an asset using HTTPS:

1$url = secure_asset('img/photo.jpg');
1$url = secure_asset('img/photo.jpg');

secure_url()

The secure_url function generates a fully qualified HTTPS URL to the given path. Additional URL segments may be passed in the function's second argument:

1$url = secure_url('user/profile');
2 
3$url = secure_url('user/profile', [1]);
1$url = secure_url('user/profile');
2 
3$url = secure_url('user/profile', [1]);

url()

The url function generates a fully qualified URL to the given path:

1$url = url('user/profile');
2 
3$url = url('user/profile', [1]);
1$url = url('user/profile');
2 
3$url = url('user/profile', [1]);

If no path is provided, an Illuminate\Routing\UrlGenerator instance is returned:

1$current = url()->current();
2 
3$full = url()->full();
4 
5$previous = url()->previous();
1$current = url()->current();
2 
3$full = url()->full();
4 
5$previous = url()->previous();

Miscellaneous

abort()

The abort function throws an HTTP exception which will be rendered by the exception handler:

1abort(403);
1abort(403);

You may also provide the exception's message and custom HTTP response headers that should be sent to the browser:

1abort(403, 'Unauthorized.', $headers);
1abort(403, 'Unauthorized.', $headers);

abort_if()

The abort_if function throws an HTTP exception if a given boolean expression evaluates to true:

1abort_if(! Auth::user()->isAdmin(), 403);
1abort_if(! Auth::user()->isAdmin(), 403);

Like the abort method, you may also provide the exception's response text as the third argument and an array of custom response headers as the fourth argument to the function.

abort_unless()

The abort_unless function throws an HTTP exception if a given boolean expression evaluates to false:

1abort_unless(Auth::user()->isAdmin(), 403);
1abort_unless(Auth::user()->isAdmin(), 403);

Like the abort method, you may also provide the exception's response text as the third argument and an array of custom response headers as the fourth argument to the function.

app()

The app function returns the service container instance:

1$container = app();
1$container = app();

You may pass a class or interface name to resolve it from the container:

1$api = app('HelpSpot\API');
1$api = app('HelpSpot\API');

auth()

The auth function returns an authenticator instance. You may use it as an alternative to the Auth facade:

1$user = auth()->user();
1$user = auth()->user();

If needed, you may specify which guard instance you would like to access:

1$user = auth('admin')->user();
1$user = auth('admin')->user();

back()

The back function generates a redirect HTTP response to the user's previous location:

1return back($status = 302, $headers = [], $fallback = '/');

3return back();
1return back($status = 302, $headers = [], $fallback = '/');
2 
3return back();

The blank function determines whether the given value is "blank":

1blank('');
2blank(' ');
3blank(null);
4blank(collect());
5 
6// true
7 
8blank(0);
9blank(true);
10blank(false);

4blank(collect());
5 
6// true
7 
8blank(0);
9blank(true);
10blank(false);
11

3broadcast(new UserRegistered($user))->toOthers();
1broadcast(new UserRegistered($user));
2 
3broadcast(new UserRegistered($user))->toOthers();

cache()

The cache function may be used to get values from the cache. If the given key does not exist in the cache, an optional default value will be returned:

1$value = cache('key');
2 
3$value = cache('key', 'default');
1$value = cache('key');
2 
3$value = cache('key', 'default');

You may add items to the cache by passing an array of key / value pairs to the function. You should also pass the number of seconds or duration the cached value should be considered valid:

1cache(['key' => 'value'], 300);
2 
3cache(['key' => 'value'], now()->addSeconds(10));
1cache(['key' => 'value'], 300);
2 
3cache(['key' => 'value'], now()->addSeconds(10));
