New undot() and reverse() methods in Laravel 8.x
Some may argue that Laravel is a framework that is bloated with methods and stuff to do everything under the sun. But in my opinion, that’s one of those things that make Laravel, “Laravel” because the more options you have out of the box, the better your life gets!
The recent release of Laravel comes with two such small “life-improvement” methods which aren’t fancy enough but you may have always wanted them.
The reverse() method
There’s now a helper method called reverse() in Illuminate\Support\Str and Illuminate\Support\Stringable using which it’s now convenient to reverse strings.
use Illuminate\Support\Str;
echo Str::reverse('raBooF');
// FooBar
echo Str::of('FooBar')->reverse();
// raBooF
The good thing about this method is it also works with multibyte strings flawlessly.
echo Str::reverse('őtüzsineT');
// Teniszütő
The undot() method
And next, the framework has got the counterpart of the Arr::dot() method called undot().
Where the Illuminate\Support\Arr::dot()method flattens a multi-dimensional array into a single level array that uses “dot” notation to indicate depth, the Arr::undot() method does exactly opposite og it.
So, for instance, if we have the following flatten array with the dot notation…
$productInfo = [
'products.desk.price' => 100
];
…we can unflatten or make it multi-dimensional using the undot() method like so.
use Illuminate\Support\Arr;
$unflattenedProductInfo = Arr::undot($productInfo);
/*
[
'products' => [
'desk' => [
'price' => 100
]
]
];
*/
