gmp_random_range — Get a uniformly selected integer
Generate a random number. The number will be between
min and max.
min and max can both be negative,
but min must always be less than max.
Esta función no genera valores criptográficos fiables por lo que no debería empelarse para propósitos criptográficos. Si fuera necesario un valor criptográfico seguro, considérese utilizar random_int(), random_bytes(), o openssl_random_pseudo_bytes() en su lugar.
minA GMP number representing the lower bound for the random number
maxA GMP number representing the upper bound for the random number
Returns a GMP object which contains
a uniformly selected integer from the closed interval
[min, max]. Both
min and max are
possible return values.
If max is less than min,
a ValueError will be thrown.
Ejemplo #1 gmp_random_range() example
<?php
$rand1 = gmp_random_range(0, 100); // random number between 0 and 100
$rand2 = gmp_random_range(-100, -10); // random number between -100 and -10
echo gmp_strval($rand1) . "\n";
echo gmp_strval($rand2) . "\n";
?>El resultado del ejemplo sería:
42 -67
