The Random\Randomizer class

Introduction

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

final Random\Randomizer

/* Properties */

public readonly Random\Engine $engine;

/* Methods */

public __construct(Random\Enginenull $engine = null)

public string getBytes(int $length)

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

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

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

public float nextFloat()

public int nextInt()

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

public array __serialize()

public array shuffleArray(array $array)

public string shuffleBytes(string $bytes)

public void __unserialize(array $data)

engine: The low-level source of randomness for the Random\Randomizer’s methods.
