gmp_random
(PHP 4 >= 4.0.4, PHP 5) gmp_random -- Random number
Descriptionresource gmp_random ( int limiter ) Generate a random number. The number will be between
zero and the number of bits per limb multiplied by
limiter. If limiter
is negative, negative numbers are generated.
A limb is an internal GMP mechanism. The number of bits in a limb is
not static, and can vary from system to system. Generally, the number
of bits in a limb is either 16 or 32, but this is not guaranteed.
Пример 1. gmp_random() example
<?php
$rand1
=
gmp_random
(
1
);
// random number from 0 to 1 * bits per limb
$rand2
=
gmp_random
(
2
);
// random number from 0 to 2 * bits per limb
echo
gmp_strval
(
$rand1
) .
"\n"
;
echo
gmp_strval
(
$rand2
) .
"\n"
;
?>
