Is there is `String.Format` method in Laravel 5?

in C# .NET we have a function like below

String.format("abc{0}", " some text");

It will output final string like below.

abc some text

Is there is String.Format method in Laravel 5?

Reason I asked this because I have below keys in .env file

UserFolder = public\User

and i want to add one more key below. SO in order to hardcode the images in code files, I want to do it in .env

UserFolder = public\User\{0}\images

Here {0} will be replaced with UserID
