PHP生成随机数

I need to generate about 5,000 random numbers in my script, but the CPU is so fast that I see tendencies in my random numbers.

For example, in the 100 first iterations, I get 80 values between 70 and 99 with rand(0,100);, which can be a REAL inconvenient.

Is there a way to solve such issue, or is randomness not achievable anymore in 2012?

I believe there could be a possibility of generating random numbers from a function executing a random number of times... but I can't figure out one.

    Are you using rand()? Consider "generating a better random value".

    Addendum; it's always good to see two sides of a coin.
