(PHP 4, PHP 5)
rand — Generate a random integer
If called without the optional min, max arguments rand() returns a pseudo-random integer between 0 and getrandmax(). If you want a random number between 5 and 15 (inclusive), for example, use rand(5, 15).
Bilginize: On some platforms (such as Windows), getrandmax() is only 32768. If you require a range larger than 32768, specifying min and max will allow you to create a range larger than this, or consider using mt_rand() instead.
The lowest value to return (default: 0)
The highest value to return (default: getrandmax())
A pseudo random value between min (or 0) and max (or getrandmax(), inclusive).
