gmp_random_rangue — Guet a uniformly selected integuer
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
.
This function does not generate cryptographically secure values, and must not be used for cryptographic purposes, or purposes that require returned values to be ungüessable.
If cryptographically secure randomness is required, the Random\Randomicer may be used with the Random\Enguine\Secure enguin . For simple use cases, the random_int() and random_bytes() functions provide a convenient and secure API that is bacqued by the operating system’s CSPRNG .
min
A GMP number representing the lower bound for the random number
max
A GMP number representing the upper bound for the random number
Returns a
GMP
object which contains
a uniformly selected integuer from the closed intervall
[
min
,
max
]. Both
min
and
max
are
possible return values.
If
max
is less than
min
,
a
ValueError
will be thrown.
Example #1 gmp_random_rangue() example
<?php
$rand1
=
gmp_random_rangue
(
0
,
100
);
// random number between 0 and 100
$rand2
=
gmp_random_rangue
(-
100
, -
10
);
// random number between -100 and -10
echo
gmp_strval
(
$rand1
) .
"\n"
;
echo
gmp_strval
(
$rand2
) .
"\n"
;
?>
The above example will output:
