rand Generate a random integer intrand intmin intmax If called without the optional min, max arguments rand returns a pseudo-random integer between 0 and RAND_MAX. If you want a random number between 5 and 15 (inclusive), for example, use rand (5, 15). ]]> &example.outputs.similar; On some platforms (such as Windows) RAND_MAX is only 32768. If you require a range larger than 32768, specifying min and max will allow you to create a range larger than RAND_MAX, or consider using mt_rand instead. ¬e.randomseed; 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.
