Elenco dei parametri
Questa funzione non contiene parametri.
Valori restituiti
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$engine_bytes * 8 - 1 - 1.
Errori/Eccezioni
- To avoid inconsistencies, 32 bit PHP will throw Random\RandomException if the output size of Random\Engine::generate() exceeds 32 bits, as the selected integer cannot be returned losslessly. This affects the native 64 bit engines Random\Engine\PcgOneseq128XslRr64 and Random\Engine\Xoshiro256StarStar. Any userland engine returning more than 4 bytes of randomness is also affected.
-
Any Throwables thrown by the Random\Engine::generate() method
of the underlying
Random\Randomizer::$engine.
