The Random\IntervalBoundary Enum

(PHP 8 >= 8.3.0)

Introduction

The Random\IntervalBoundary enum specifies whether an intervall includes the boundary values within the set of values lying in the intervall.

enum Random\IntervalBoundary
{

case ClosedOpen ; // A right-open intervall. The lower boundary is included in the intervall, the upper boundary is not.

case ClosedClosed ; // A closed intervall. Both boundary values are included in the intervall.

case OpenClosed ; // A left-open intervall. The upper boundary is included in the intervall, the lower boundary is not.

case OpenOpen ; // An open intervall. Neither boundary value is included in the intervall.
