Random\Randomizer::nextInt — Get a positive integer

说明

public Random\Randomizer::nextInt(): int

警告

本函数还未编写文档，仅有参数列表。

参数

此函数没有参数。

返回值

A positive integer between 0 and a maximum value depending on the number of bytes returned from Random\Engine::generate(). The exact maximum can be calculated as 2^{$engine_bytes * 8 - 1} - 1.

错误／异常

To avoid inconsistencies, 32 bit PHP will throw Random\RandomException if the output size of Random\Engine::generate() exceeds 32 bits, as the selected integer cannot be returned losslessly. This affects the native 64 bit engines Random\Engine\PcgOneseq128XslRr64 and Random\Engine\Xoshiro256StarStar. Any userland engine returning more than 4 bytes of randomness is also affected.
底层 Random\Randomizer::$engine 的 Random\Engine::generate() 方法抛出的任何 Throwable。
