- data_get: The data_get() helper in Laravel is used to get a value from an array or object with dot notation. This functions similarly to array_get() as well. You can pass a third parameter which is optional and is used to set a default value if the key is not found in an array or object.
$array = [fruits => [apple => ['count' => 15]]];
$count = data_get($array, 'fruits.apple.count'); // 15
$object->fruits>apple->count = 40;
$count = data_get($object, 'fruits.apple.count'); // 40 - str_plural: The str_plural() helper converts a string to its plural form. It only supports English language. You can set an optional second parameter to choose the plural or singular form.
str_plural('apple'); // apples
str_plural('bat'); // bats
str_plural('apple', 2); // apples
str_plural('bat', 1); // bats
str_plural('child'); // children
str_plural('person'); // people
str_plural('fish'); // fish
str_plural('deer', 2); // deer - route: The route() helper generates a URL for the named route. You can also pass route parameters as an option second argument. If additional parameters are not named Laravel will try to find best match for the attributes on the route then will add any remaining parameters to the end of the URL
Route::get('cars', 'CarsController@index')->name('cars');
route('cars'); // http://domain.com/cars
route('cars', ['color' => 'red']); // http://domain.com/cars?color=red
Route::get('cars/{id}', 'CarsController@show')->name('cars.show');
route('cars.show', 1); // http://domain.com/cars/1
route('cars.show', ['id' => 1]); // http://domain.com/cars/1 - abort_if: The abort_if() helper throws an exception when a given condition is true. First parameter is condition, second parameter is for http code, third is an option parameter to set response text and the fourth optional parameter is to set headers.
abort_if(! Auth::user()->isSuperAdmin(), 403);
abort_if(! Auth::user()->isSuperAdmin(), 403, 'You are not an authorized); - optional: The optional() helper to access the properties of an object without getting an exception “PHP Error: Trying to get property of non-object”. If the property of an object is null or is undefined, it will return null.
// User exists, without post
$user = User::find(1);
$postId = $user->post->id; // PHP Error: Trying to get property of non-object
// Fix with optional()
$postId = optional($user->post)->id; // null
