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.
