srand() problem question

[Anon]

Hi!

I red in the php book that i have to use the srand() function before the random(). I have 2 random() functions in the same .php file. Have i to use also two times the srand() function or one time is enough?

Thanks for your answer!

Just once. All the calls to random() get their values from the same random number generator; srand() acts to "warm up" that generator.
