                                     rand

   (PHP 3, PHP 4 )
   rand -- Generate a random value

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).

   Example 1. rand() example
   <?php
   echo rand() . "\n";
   echo rand() . "\n";
   echo rand(5, 15);
   ?>

   The above example will output something similar to:
7771
22264
11

     Note: On some platforms (such as Windows) RAND_MAX is only 32768.
     If you require a range larger than 32768, consider using mt_rand()
     instead.

     Note: As of PHP 4.2.0, there is no need to seed the random number
     generator with srand() or mt_srand() as this is now done
     automatically.

     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().
