The Random\Randomizer class

Introduction

(PHP 8 >= 8.2.0)

Provides a high-level API to the randomness provided by an Random\Engine.

Class synopsis

public getBytes(int $length): string

public getBytesFromString(string $string, int $length): string

public getFloat(float $min, float $max, Random\IntervalBoundary $boundary = Random\IntervalBoundary::ClosedOpen): float

public getInt(int $min, int $max): int

public nextFloat(): float

public nextInt(): int

public pickArrayKeys(array $array, int $num): array

public __serialize(): array

public shuffleArray(array $array): array

public shuffleBytes(string $bytes): string

public __unserialize(array $data): void

Properties
