The rand() function generates a random integer.
int rand ( void )
int rand ( int $min , int $max )
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).
The above example will output something similar to:
7771 22264 11
Parameter | Description |
---|---|
min | The lowest value to return (default: 0) |
max | The highest value to return (default: getrandmax()) |
A pseudo random value between min (or 0) and max (or getrandmax(), inclusive).
