$rand Generates a random number |
Usage |
$rand(<max>) |
Description |
| Returns a random integer number from 0 to max inclusive. You can repeat sequences of random numbers by calling srand with the same seed value. If srand has not been called $rand is automatically seeded with value of 1. If no <max> is specified, this function returns an integer between 0 and RAND_MAX that is system dependent. |
