The Random\IntervalBoundary Enum

(PHP 8 >= 8.3.0)

简介

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

enum Random\IntervalBoundary
{

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

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

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

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

}
