Description
int
rand ( [int min, int max])
If called without the optional min,
max arguments rand()
returns a pseudo-random value between 0 and
RAND_MAX. If you want a random number
between 5 and 15 (inclusive), for example, use rand (5,
15).
In older versions of PHP, you had to seed the random number generator
before use with srand(). Since 4.2.0 this is no
longer necessary.
Note:
In versions before 3.0.7 the meaning of
max was range. To
get the same results in these versions the short example should
be rand (5, 11) to get a random number
between 5 and 15.
See also srand(),
getrandmax(), and
mt_rand().
