Range

The Range component provides a way to create a range of integer values.

Ranges represent sets of integer values with optional lower and upper bounds. They support containment checks, iteration, and bound manipulation.

Usage

Creating Ranges

There are four types of ranges, created with constructor functions:

@example('collections/range-creating.php')

Containment Checks

All range types support contains():

@example('collections/range-containment.php')

Iterating Over Ranges

Ranges with a lower bound (FromRange and BetweenRange) are iterable:

@example('collections/range-iterating.php')

Manipulating Bounds

Ranges can be combined with new bounds to create different range types:

@example('collections/range-manipulating.php')

See src/Psl/Range/ for the full API.
